This week at the Desk of Ladyada, we're getting back into the swing of releasing one or two new products a week after dealing with some tariff-related chaos. Last week we launched the Sparkle Motion Stick and the SEN6x Adapter. Next week, look out for the OPT4048. For the OPT4048, we wanted to easily plot the CIE x & y to a color graph—which used to mean writing a lot of JavaScript (something I haven't done in 15 years). Thankfully, Claude helped generate code, and now it's up and running! Check it out. This week, we also designed breakouts for: ACS37800 30A Monitor, VEML6046, and a Stemma QT adapter for Raspberry Pi bq25798 Solar MPPT Charger. And for this week's The Great Search – 30 Amp Barrier Terminal Blocks

This week's EYE ON NPI is a follow up to one we did a few years ago on the similarly-named BQ25792 (https://blog.adafruit.com/2021/05/06/eye-on-npi-ti-bq25792-i2c-controlled-1-4-cell-5a-buck-boost-battery-charger-eyeonnpi-adafruit-digikey-adafruit-digikey-txinstruments/). The BQ25798 (https://www.digikey.com/short/vnr279pz) builds on the '92 by adding selectable dual inputs and true MPPT solar support. This chip is inexpensive, powerful and can handle almost any battery and power source matching you desire. Let's look at some specifications: High power density, high integration buck-boost charger for 1-4 cell batteries supporting USB PD 3.0 profile – Integrates four switching MOSFETs, BATFET – Integrates input and charging current sensing Highly efficient – 750-kHz or 1.5-MHz switching frequencies – 5-A charging current with 10-mA resolution 96.5% efficient: 16-V battery at 3A from 20V Supports a wide range of input sources Autonomously sampled open circuit voltage (VOC) maximum power point tracking (MPPT) for charging from a photovoltaic panel – 3.6-V to 24-V wide input operating voltage range with 30-V absolute maximum rating – Detects USB BC1.2, HVDCP and non-standard adapters Dual-input power mux controller (optional) Narrow voltage DC (NVDC) power path Backup Mode with Ultra-fast switchover to adjustable voltage Powers USB port from battery (USB OTG) – 2.8-V to 22-V OTG output voltage with 10-mV resolution to support USB-PD PPS – OTG output current regulation up to 3.32 A with 40-mA resolution Flexible autonomous and I2C mode for optimal system performance Integrated 16-bit ADC for voltage, current, and temperature monitoring Like the '92, the BQ25798 (https://www.digikey.com/short/vnr279pz) supports any size battery. We have lots of battery packs in the Adafruit shop, and in particular we use 1S batteries – if there are more batteries, they are wired in series. But there's lot of folks who are building robotics that require higher voltages, so they have 2S, 3S, or 4S batteries. This charger can handle any of 'em, and you can configure the battery pack size using a simple resistor on the PROG port. In this case it also allows the chip to run in 'standalone' mode without the use of I2C to configure. The biggest improvement you get with the BQ25798 (https://www.digikey.com/short/vnr279pz) is true solar MPPT support. The BQ25792 had VINDPM and IINDPM – the ability to track the input voltage to make sure it is not drooping from overdraw. While this lets you get pretty-close-to-MPPT it isn't true power-point-tracking which requires perturbation around the voltage to adjust as light and temperature affect the solar panel's efficiency. The '98 does this 'right' and even has a K Factor adjustment register - you can tweak this to get the best results based on different weather/temperature (https://www.ti.com/video/6287049638001)- or stick to the default value for good results. Another new feature is 'selectable dual-inputs' what this means if you can set up two power inputs - say DC plug and Solar - and then have the chip switch between them. This is particularly useful because you can't just use two OR'ing diodes to select the power source: the solar panel might have a higher initial open-voltage but can't supply as much current as a DC plug. I2C lets you select which one is priority! The BQ25798 (https://www.digikey.com/short/vnr279pz) also has many of the cool features we liked in the BQ25792: On-The-Go mode where you can turn the buck-boost around and have it generate a variable voltage output, say 5V for powering other USB devices. Another thing that works is powering over USB where you can have the BQ negotiate 'high voltage' support from USB 3 ports. Note that this isn't USB Type C power negotiation, for that you'll want to get a separate USB Type C PD negotiation chip like the TPS25750D (https://www.tij.co.jp/jp/lit/ml/slpp103/slpp103.pdf)...we're hoping there's a future version with PD built in! There's also a built in 16-bit ADC that you can use to monitor various voltages and current draw. While you can charge the battery in 'standalone' mode - you really do need I2C to get the best performance and capabilities. Thankfully there's not a huge number of registers, and SDA/SCL can be 3 or 5V logic signals so you should be able to get it working on anything from an ATmega328 to a Raspberry Pi. We like the high integration: you really only need a few passives and an inductor to get a fantastic all-in-one charger for any lithium ion battery pack. If you're intrigued and would like more information, you've come to the right place! DigiKey has the BQ25798 (https://www.digikey.com/short/vnr279pz) in stock right now for immediate shipment. Order today and you can start designing your solar-powered products of the future by tomorrow afternoon.

In this week's episode of the podcast, I'm going to run you through the basics of solar power and it's uses for overlanding. I see people asking lots of questions in overlanding and camping groups and forums, so while I'm no electrician, I've been using solar for the last 4 or 5 years and I've learned a lot. I was in the same place as a lot of us 5 years ago where solar seemed really intimidating and scary, but once I got into it, it's really pretty straightforward and there are so many valuable uses that it's a powerful tool for your overlanding build. As I mention in the video, here are a couple of helpful links to related articles that may help if you're getting started in solar. Mono vs. Poly: Solar Cells Comparison: https://sunvivalguide.com/amorphous-vs-monocrystalline-vs-polycrystalline-solar-panel/ Solar calculator: https://mowgli-adventures.com/rv-solar-calculator/ And here are some of the solar products I've used over the years that I liked: The first 100W Renogy Solar panel with controller that I ran on my Xterra ($130 and includes panel, controller, and cords): https://amzn.to/42YED7p Odyssey AGM Starter battery (ran this in both my Xterra and again in my Frontier-if you're not in a Nissan truck, verify the battery size for your application): https://amzn.to/3SYXnyP I built a portable power bank on the cheap using this battery (100AH LifePo4): https://amzn.to/3T0a9gC And I put that battery in a pre-made battery box for tons of capacity for around $300 total: https://amzn.to/3Ifwpyj If you have a solar panel, but want a decent budget controller to allow you to hook it up to a battery, this one is great and it's $18: https://amzn.to/3P0oQzh Or, if you want a better MPPT controller, this one is under $70 and has bluetooth connectivity and a phone app: https://amzn.to/3TdyZuK Here's that Allpowers power bank and it comes with a 200 watt flexible panel (I'm going to mount mine to the top of my RTT for about $500 total including the power bank and the solar panel): https://amzn.to/49Tkfqi

This is some of what Mr. Shell has to say. “Topping the list this year is Microsoft (MSFT). Applied Materials (AMAT) took second place. In third place is Woodward (WWD). Best ESG Companies Methodology To build the 2023 100 Best ESG Companies list, we started with each company's ESG sustainability score created by Dow Jones Newswires, an IBD affiliate. These scores capture a broad spectrum of information on the ESG profile of more than 6,000 global companies. On Aug. 24, IBD asked Dow Jones for an ESG-scored list of all the U.S.-traded companies it tracks, a total of 2,067. We then cut the list to 1,559 companies on Aug. 25 by removing nonpublic companies and companies with stock prices below $10 a share. We also removed any companies that lacked sufficient data to create an IBD Composite Rating. We further qualified the list by removing those companies that did not meet or beat the S&P 500 in the past five years.

Please go to this podcast's webpage for links to the actual articles for more company and stock information. Also, some companies might be covered more than once and there are also 4 article links below that time didn't allow me to review them here. ------------------------------------------------------------- 1. Best Hydrogen ETFs And Stocks. Plus… Today, I'm starting with the article 7 Hydrogen Stocks You Better Be Buying on Each and Every Dip, by Ian Cooper, on investorplace.com. Here's some of what Mr. Cooper says about his picks. “1) Global X Hydrogen ETF (NASDAQ:HYDR) It's up to $10 a share and could test $12 a share, all because of the growing demand for hydrogen… as I noted on July 17, with an expense ratio of 0.50%, this one invests in companies involved in all aspects of hydrogen production, distribution and use. 2) ALPS Clean Energy ETF (NYSEARCA:ACES). With an expense ratio of 0.55%, the ETF offers diversification and exposure to companies involved with renewables and clean technology… While it's finding resistance above $50, eventually I'd like to see it test $60 a share again soon. 3) Defiance Next Gen H2 ETF (NYSEARCA:HDRO). With an expense ratio of 0.30%, the ETF invests in companies that generate at least 50% of their revenue from involvement with hydrogen-based energy sources, fuel cell technologies and industrial gases. While it's been volatile, it has a strong history of bouncing back from excessively oversold conditions. 4) Air Products & Chemicals (NYSE:APD) Owns more than 100 hydrogen plants around the world and is involved in more than 250 projects. Air Products & Chemicals [has] a yield of 2.32%. The company is also working on a $7 billion hydrogen joint venture in Saudi Arabia. 5) Bloom Energy (NYSE:BE) Is another one of the hot ‘must own' hydrogen stocks… Analysts at RBC Capital are also bullish… the firm just initiated coverage with an outperform rating with a price target of $24 a share. 6) Plug Power (NASDAQ:PLUG) Has traded essentially flat this year, but it's still a solid long-term bet on hydrogen… Northland Securities analysts just upgraded the stock to ‘outperform' from ‘market perform' with a price target of $22 a share. 7) Fusion Fuel Green (NASDAQ:HTOO) Is still a pre-revenue company, but it has some impressive contracts. For one, it signed a 10-year offtake contract with European developer Hydrogen Ventures for 30 tons of green hydrogen per year.'' End quotes. ------------------------------------------------------------- 2. Best Hydrogen ETFs And Stocks. Plus… Now continuing with the alternative energy theme is this piece titled 3 Alternative Energy Stocks With Multibagger Potential. It's by Faisal Humayun and found on investorplace.com. Mr. Humayun includes these points about his picks. “1) Plug Power (NASDAQ:PLUG) PLUG stock has trended lower in the last 12 months and it's a golden opportunity for long-term investors to accumulate. With the company providing end-to-end solutions in the hydrogen economy, the growth visibility is robust… With significant expansion plans, revenue is likely to increase to $5 billion in 2026 and further to $20 billion by 2030… I believe that PLUG stock is poised for multi-bagger returns. 2) First Solar (NASDAQ:FSLR) stock has surged by 135% in the last 12 months. However, considering the growth momentum, First Solar stock remains undervalued at a forward price-earnings ratio of 27.1. 3) Enphase Energy (NASDAQ:ENPH) stock has been trending lower and I see this downside as a good accumulation opportunity. At a forward price-earnings ratio of 30.5, the growth stock looks attractive with an investment horizon of five years… Enphase identifies itself as the world's leading supplier of microinverter-based solar-plus-storage systems.” End quotes. ------------------------------------------------------------- Leading Sustainable Agricultural Related Stocks Many investors wonder what sustainable agricultural-related stocks there might be. Well, this article is for you. It's titled Benefits of Sustainable Investing: 3 Companies Leading The Way by Shoshana Weizenblut on finextra.com. Now a few comments by Ms. Weizenblut on her picks. “1) AGCO: Advancing Agricultural Sustainability AGCO integrates sustainability into its core business strategy, emphasizing innovation and technology to make agriculture more efficient, productive, and environmentally friendly. For instance, AGCO's Fendt Vario tractors leverage fuel-efficient designs and advanced technology to reduce environmental impact. The company's Precision Planting solutions help farmers optimize planting and yield, thereby minimizing waste and enhancing food security. 2) ICL Group: Promoting Sustainable Agriculture and Nutrition ICL Group, a leading global specialty minerals company, and one of the largest fertilizer manufacturers in the world, offers another attractive opportunity for sustainable investment. ICL's operations center around producing a sustainable food supply, focusing on soil health, plant nutrition, and food quality. ICL's innovative fertilizers are designed to increase crop yields while decreasing the environmental footprint.

This week's EYE ON NPI is enjoying the beautiful weather with you, whether sitting in the sun or lounging in the shade - all's good because we've got Nexperia's NEH2000BY Energy Harvesting Power Management IC with embedded solar MPPT capability! (https://www.digikey.com/en/product-highlight/n/nexperia/neh2000by-energy-harvesting-power-management-ic) This tiny, low-cost chip is a one-stop solution for extending the life of your product by making it powered by small solar cells. This chip is perfect for wearables or miniature sensor nodes, maybe with a LoRa radio, WiFi or Bluetooth Low Energy where space and pricing is important. For example, an asset tracker, traffic monitor, activity watch, or agricultural sensor network: stuff that is outside anyways so it'll be designed for outdoor use and have lots of sun exposure. We've covered other MPPT tracking solar harvesting chips (https://blog.adafruit.com/2021/04/23/eye-on-npi-max20361-tiny-single-multi-cell-solar-harvester-maximintegrated/), and the NEH2000BY has some advantages in size, cost and simplicity. Either use it to increase the time between charges, or use it to have your product be fully encased with no need for charging at all, thanks to the power of the SUN (https://solarsystem.nasa.gov/solar-system/sun/galleries/?page=0&per_page=25&order=created_at+desc&search=&href_query_params=category%3Dsolar-system_sun&button_class=big_more_button&tags=sun&condition_1=1%3Ais_in_resource_list&category=51) The Nexperia NEH2000BY energy harvester (https://www.digikey.com/short/hpnfttw3) is designed specifically for use with solar cells because cells collapse under high current draw - which is what batteries want when they are charging up so that they can be ready to go ASAP! When drawing current from a solar cell, at the very beginning the voltage is very high, then is slowly drops down as more is drawn until the input voltage collapses completely. So you have to be very careful when drawing current - too little and you lose out on efficiency, too much and your power goes away completely. There's a 'sweet spot' right in the middle, where you can get the most power output, which is called the Max Power Point. (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) And this point varies with how much sunlight you get - so it isn't something you can pre-program in with a comparator or anything. Instead, the energy harvester has to wiggle the power draw forward and back to find the maximum point. For large-scale solar installations, you'd have a microcontroller do the math for you, and adjust throughout the day - it isn't hard to do MPPT it just takes measurement and computation. But in small and low-current situations, you can't spend all your power budget on a microcontroller to manage your battery charger. First up, almost no extra components are needed: just a stabilization capacitor plus a capacitor for the switched-cap boosting doubler. Note that there's no inductor because it seems to use a switched-cap boosting method for approximately 2x voltage output - so you will need to spec a panel that, when the MPPT voltage is approximately doubled, you'll have about 0.3V above the battery voltage. There's some math in the datasheet to work this out but basically in the end, use a panel with an open-circuit voltage - Voc - that is about 0.7 times the battery voltage. So, e.g. if you're using a Lipoly (https://www.digikey.com/short/h02tmj1q), with a VBat of 4.2V, use a 3V solar panel - which is very common and inexpensive. For NiMH cells, add up the total series voltage before multiplying by 0.7 for the Voc desired. To keep your battery from over-charging, either use a separate battery charger chip that will do the constant-current to voltage-limited charging, or use a low cost over-voltage protection (OVP) chip as recommended in the datasheet. If you'd like to integrate the Nexperia NEH2000BY Energy Harvesting Power Management IC (https://www.digikey.com/short/hpnfttw3) into your next solar-powered product, thank your lucky stars because DigiKey has the NEH2000BY in stock right now at a great price for immediate shipment. With the long summer days ahead, you can order today and be max-power-point'ing before the sun sets tomorrow.

This podcast with Wes and David delves into the topic of wind turbines and the misconception that amperage is the only indicator of performance. They discuss the importance of the MPPT (Maximum Power Point Tracking) controller in regulating the performance of the turbine. The MPPT controller is responsible for analyzing the incoming voltage from the wind turbine and the state of the battery to determine what the amperage should be. This is important because simply increasing the amperage without considering the voltage and battery state can actually decrease the performance of the turbine. Wes and David also discuss the benefits of using MPPT controllers, including the ability to maximize the power output of the turbine and extend the life of the battery. They provide valuable insights on how to properly set up and maintain a wind turbine system for optimal performance. Overall, the podcast is an informative and insightful discussion on the importance of understanding the role of the MPPT controller in wind turbine systems and how it can affect performance.

This week's EYE ON NPI is so flexible, it's thinking of joining the Rockettes (https://www.rockettes.com/christmas/)! It's TDK's BCS Series Low Illumination Film Solar Cells that are designed for direct integration of products, particularly wearables or credit card size and thickness electronic components. This amorphous panel comes with 6 cells, each about 0.4V open-circuit, for a total of about 2.6V output and 30mA. The nifty part about this panel is just how incredibly thin it is - only 0.2mm which means it can be bonded onto almost any surface or device. And unlike most panels that are made of monocrystalline cells, it is ultra flexible and will not crack or break. TDK's BCS series are thin, lightweight, and flexible solar cells offering high power generation efficiency under fluorescent and LED light sources. The cells are made of amorphous silicon film substrate, and designs can be customized according to various shapes and applications. Because BCS series solar cells offer output stability in low and dim light, they are suitable for use in products used indoors. Additional benefits of solar cells include cost reduction in electrical wiring and battery replacement. When used in combination with a primary battery, solar cells can extend battery life and usage time of rechargeable devices. BCS series solar cells can be used in applications such as watches, wearables, beacons, wireless sensor nodes and other IoT power supply applications, smart cards and locks, and more. Compared to many other ultra-low power source harvesting techniques (https://en.wikipedia.org/wiki/Energy_harvesting) like vibration/piezoelectric or heat, solar is very efficient, very small and very easy to use. Amorphous cells are a great option for folks who want to have indoor-powered electronics without hassle. Simply connect the two terminals to you circuitry plus and minus: when there's ambient light, you'll get voltage output. These panels may look familiar if you've ever had a solar-powered calculator (https://en.wikipedia.org/wiki/Solar-powered_calculator) - often times you'd have to hold these up to a lamp to get them 'kick-started'. Those pocket calculators with LCDs are a great example of ultra-low current draw electronics that could run off of a tiny cell, we're talking under a milliamp here. That's something to keep in mind when integrating panels, they produce about 1/10th of the power folks think they do! The biggest challenge that folks have with implementing solar panels is that they don't really act like a true voltage source or current source: they're somewhere in the middle, like a negative diode. With solar panels, the voltage and current vary constantly depending on sunlight available. They are unstable! That instability confuses electronics battery chargers, which causes them to do one of two things: rapidly turn on and off as they try to draw more current from the panel than possible and/or draw much less current than they can, to keep the voltage from collapsing. So you've got a few choices for implementing this panel: 1) have electronics that is OK with a widely varying input voltage: about 2V to 5V max, and will brownout safely when light disappears all of a sudden. Then, make sure it uses less than a few mA of current so that it doesn't collapse the IV curve by drawing too much power 2) use a super capacitor or rechargeable battery of some sort, that is trickle charged by the panel. once the voltage on the cap gets to a certain amount, the circuitry can use that to perform whatever calculators or data transfer required. 3) use a smart energy-harvesting chip like the LTC3588 (https://www.digikey.com/en/products/detail/analog-devices-inc/LTC3588EMSE-1-TRPBF/2216345) to manage the load on the panel and either charge a battery or directly power electronics with a cleaner supply than directly powered from the solar cell. Sometimes these chips can even operate as a MPPT charger (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) to get the very max power possible. If you're interested in adding a super-flexible and ultra-thin green power supply to your next design, check out the BCS4430B6 (https://www.digikey.com/short/vwm3z35j) and friends. The TDK BCS Series Low Illumination Film Solar Cells (https://www.digikey.com/short/vwm3z35j) are in stock right now at Digi-Key for immediate shipping! Order now and you will be relaxing in the sun by tomorrow afternoon. See these at Digi-Key at https://www.digikey.com/short/vwm3z35j

In this podcast we talk about the new UL standard for PV, which replaces UL 1703 for PV with UL 61730, which took place in December of 2020. You can still use UL 1703, just if you come out with a new module design, it needs to comply with UL 61730, which makes things easier, since it is the same test around the world, instead of having a different test for the US and Europe for instance.   We also talk about the new UL 3741 PV Hazard Control Standard, aka the Rapid Shutdown standard, which is another way of complying with 690.12 in the 2020 NEC, so you can perhaps have up to 3 modules in series after shutdown now. Mid Circuit Interrupters (MCI) on every third module maybe all you need for rapid shutdown as long as it is a UL 3741 listed solution. This is big news and a new way to deal with rapid shutdown. An MCI is likely to be a switch that does not do maximum power point tracking (MPPT), or you can have a dc-to-dc converter (optimizer) that does MPPT on a group of 3 PV modules.   To learn more about energy storage, solar, the building codes, the NEC and everything else, go to www.solarsean.com

We're going to wrap up this series with Wes and David talking about the charge controllers. The review the key types, the MPPT, PWM, and the bulk controller and what they do.

Mixing Solar PanelsAre you killing the output of your solar array? In this week's podcast, Wes and David discuss the problems you might face when mixing different solar panels into one system. It's not uncommon for homeowners to add solar panels to their current solar panel array as budget allows. Be sure to listen to our podcast to find out how you can still get maximum production with mismatched solar panels.So, what's the big deal? Isn't it just a simple addition?Not exactly. Your solar array is only as strong as the weakest panel. That's right, connecting a panel with a lower output to the array drags the power output down.Here are some tips to make it easy to understandConnecting different solar panels in a single array is not recommended: You may reduce the voltage or current which leads to lower wattage output.If you can't pass up a bargain, try to buy solar panels with similar voltage and current.Charge Controllers:Connect each "sub-array" to its own charge controller, or find a charge controller with multiple input feeds. Then combine the arrays by connecting them to the same battery bank.Connecting mixed panels to an MPPT charge controller may confuse the controller and make it impossible to determine the ideal operating voltage and current. Instead, you'd do better to save by purchasing multiple PWM controllers.Grid Tie Systems:The best practice is to wire each array to its own grid tie inverter, wired into a breaker in your fuse panel.Wiring in Series:If your solar panels are the same current: Wire them in series.When wiring in series (increases voltage): all panels will produce the same current of the lowest panel.Two 8.5 Amp panels wired with an 8 amp panel will produce 8 Amps.Wiring in Parallel:If your solar panels are matching voltage: Connect them in parallel.When wiring in parallel (increases current): all panels will operate at the lowest voltage rating.Two 40 VOC panels wired with a 30 VOC panel will produce 30 VOC.Need help with solar panel wiring?

Despite Wes being under the weather, he and David talk about the charge controller and how important it is in both your wind and solar applications. They discuss what function it performs and many of the popular controllers on the market.There are so many options and features, like solid state versus mechanical relays, MPPT or PWM, divert or disconnect, and so on.  It can be confusing.  This week's podcast breaks it down to let you know what controller is right for your application.Listen to find out why your wind turbine NEEDS a dump load and what happens to your MidNite Classic if your wind turbine produces high voltage.Recommended Links:Video: Choosing the Right Solar Charge ControllerCharge Controllers We Carry:Hybrid Charge ControllersSolar Charge ControllersAll-In-One Pre-Wired Charge Controller BoardsMidNite Classic MPPT Charge Controllers & Voltage Reducing Device (VRD)Originally aired 12/20/2017

Foundations of Amateur Radio The transceiver you use to get on air and make noise needs power to operate. The traditional voltage for our amateur equipment is 13.8 Volts. Why not 12 Volts you ask. The short answer is chemistry, but let's move on, there is lots to cover. Generally that 13.8 Volt is specified with a +/- symbol and some percentage. For my radio it's 15%, which means that if I plug it into power that's somewhere between 11.7 Volt and 15.9 Volt, I'm good to go. Then when you look a little closer at the specification you'll see that my radio draws 22 Amp. That's a whole chunk of juice that needs to come from a power supply. Of course that means that you'll also need to deal with 22 Amp fuses, wire capable of dealing with 13.8 Volt at 22 Amp, and connectors that won't melt when you do that. If you look closer again, you might notice that 22 Amp is when you're using the radio at maximum power, that is, 100% duty cycle and 100% power, and only during transmit, in the case of my radio, 100 Watts for HF. So, if I'm using a digital mode, AM or FM, at 100 Watts on HF, my radio says it will draw 22 Amp at 13.8 Volts. Those numbers aren't correct of you're using CW or SSB. A rough number to work with for CW is 40%, that means if you're doing CW for a minute, that's the equivalent of key down at a 100% for 40 seconds and key up at 0% for 60 seconds. SSB is roughly 4 times as efficient as AM, about 25% duty cycle, but realistically it's more like 20%, since your power consumption depends on how much you're yelling into the microphone. If you take long breaths, 0% power, whistle into the microphone, 100% of SSB, or 25% of overall power. Now all this gets even more interesting if you consider that you're not just transmitting all the time. If you're only transmitting half the time, you need to take your power consumption down another 50%, so SSB might be 10%, CW only 20% and the digital modes 50%, from the perspective of the power supply. So you want to go portable and need batteries. Batteries don't come in 13.8 Volt versions. So 12 Volts. Get the number of amp hour and you're good to go right? Nope. Your battery doesn't just run at 12 Volts and then all of a sudden stop, it runs down, you've seen it in a torch or a Walkman when the tape got slower and slower. A 26 Ah battery should give you 26 Amp for an hour at 12 Volts, but if you actually do that, you'll need to buy a new battery, because you'll have destroyed the one you just exhausted. All of this then starts a conversation about chargers, which incidentally might put out 14.4 Volts. You might turn to solar panels, which at peak power operate at something like 18 Volts, then you stumble into the world of PWM vs MPPT solar converters or charges. Then there's the joys of over and under current, battery discharge rates, continuous versus intermittent charging, different battery types, battery safety, storage, weight, out-gassing and more fun than you'll want to know about on your morning commute. And I haven't even talked about battery isolation, HF interference from chargers and inverters, the differences between powering your radio straight from a battery or via a DC to DC converter, using 240 Volts, or if you're in the USA 120 Volts in the field, generators, compatibility with others and how much all this might cost and if you need to invest in lotto tickets to pay for this experience. One tool I stumbled across in my travels is the Four State QRP Group website which has the W1PNS / WA0ITP / AB8XA Battery Life Estimator, which in a single web page gives you the ability to say what mode you'll be using, for how long with what battery size and how much radio draw and it'll tell you how much more battery you'll need to get the job done. Very handy for a contest that you're hoping to operate portable from a battery. This all to say that power is a very deep rabbit hole and it will take you some time to figure out where your use pattern puts your requirements and budget. Here be dragons. I'm Onno VK6FLAB
