One of the most annoying realities of our electronic lifestyle is that so many of our electronic must-haves are battery operated. And depending on how often we use them, the life of their batteries can be from a single day to a couple of weeks. While a package of disposable batteries, depending on their size, usually costs less than $ 5, if they are powering an addiction forming device lie a GameBoy, you may burn through them the way a chain smoker burns through a pack of cigarettes.
While TV remotes, flashlights, and smoke detector batteries may only need changing once or twice a year, GameBoys, MP3s, and cell phones are different stories. Not only that; some of the most-used battery-powered devices require not one, but two batteries. The simple truth is, even disposable batteries can make a dent in the entertainment budget.
Not only that; actually disposing of disposable batteries has become an issue, and many landfills are no longer taking them because of the danger they pose to groundwater. Fortunately, many battery manufacturers have been ahead of the environmental curve in addressing this issue, and are now marketing rechargeable batteries to replace disposable ones. And they have gone one environmental step further by creating the solar battery charger.
Advantages Of Solar Battery Chargers
A solar battery charger has two advantages; Unlike wall chargers, it does not use energy which you have to pay for to recharge your batteries, and unlike wall chargers, it does not require an electrical outlet. A solar battery charger has built in solar panels which, when placed in a sunny locations, gather the sun's rays, which the charger connects to free electricity and feeds to your rechargeable battery or batteries.
As long as you have sun, you'll have a way to keep you electronic devices up and running; and a solar battery charger can get your batteries fully recharged in as little as three hours on the brightest days. Most rechargeable batteries are equipped with a light to let you know when they have reached their full charge.
A solar battery charger is not large; in fact it is easily transportable so that you can move it to whatever location will provide the best sun exposure. With a solar battery charger and rechargeable batteries, you need never worry about running out of power for your electronic device again. And even better, you will be powering them with free, renewable, clean solar energy, stored in rechargeable batteries which require no environmentally-threatening disposal!
RV batteries not charging properly. Fix Solar Panel Power Loss. How to fix low battery charging. How To Test Solar Panel Power Loss. # 1 cause of solar panel charging power loss. RV batteries not charged. RV batteries reduced charging, low battery /increase batteries power not fully charged, loss of amps. What to do. increase RV Solar Panel location to avoid power loss save batteries, Low power charging and loss. Why low amps power out. RV Power loss or boost solar power. How To Maximize Solar Panel Output. The effect of shade on a solar panel. Charge solar batteries with little power loss. Testing RV and House Solar Panel Voltage loss from shadow. you are loosing power from cast shadow and is a very big loss. We test the voltage loss in this video. Low power in batteries when using tv or lights overnight. Low charge voltage, low charge amps all caused by shadow. This will answer why won’t my solar panels charge better or why do my batteries die so fast, maybe discharge fast. It isn’t discharging fast, but rather not charging fully. Solar charging solutions.
See how the effect of shade causes voltage droopy shade and effects solar charging problems. Want to know ‘why won’t my solar panels keep charging’, to keep your solar panels charging without loosing power of having power loss, look at the effect of shade on your rv battery. Not charging is not necessarily no sun but the effect of low voltage, power loss, loosing power and the effect of shade. If you don’t fully charge batteries for overnight use, your batteries will discharge fast. Remember the reason we don’t want shade on on solar panels. Keep it in mind and you will get maximum solar power for your rv and save your batteries.
In this video we are building a 576wh #portable #solar #generator for off grid or grid down power. This kind of solar generator is useful for many renewable power applications. Once build and put in to use, it generates 100% free energy for emergency power, communications, amateur radio, boondocking, van or RV life, to keep food or meficine refrigerated during grid down emergencies.
– 576 watt hours, 45amp hours
– 2000 charge cycles
– 30A ports
– 2x USB ports
– Internal Bluetooth battery monitor
– 4x DC Powerpole ports
– Every port is individually fused
– MPPT charge controller
– Dual Solar inputs
– Total weight 18lbs (8.3kg)
– Easy maintenance
– Replaceable Components
– Optional pure sinewave inverter
– Easy to build
The closest commercial product is the Goal Zero Yeti 400 Lithium. Our diy solar power generator will outperform the Yeti Lithium, (unless you need an inverter), the Yeti has one built in, but an onverter is optional in the DIY Solar Generator . Most people don’t need AC power or the inverter with a solar generator. They just need tthe right connectors for their gear.
An interesting feature on the solar generator is the wireless battery monitor from Thornwave labs. The battery monitor is a Bluetooth enabled shunt using Bluetooth SE to send information about the state of the system straight to our mobile phone. it’s also got an API to get data out to something like a raspberry pi or arduino for data logging.

Solar chargers MPPT VS MWP explained.
Each has it’s advantage and each has it’s disadvantage.
I will show you the difference.
MPPT must have a minimum voltage from the batteries. You can not charge a flat dead battery with the MPPT charger. The MPPT charger can deliver more AMPs and can run different voltages.
The MWP charger will always try and charge a battery no matter what the state of charge is. The MWP charger can charge a flat / totally dead battery. Or at least it will try. But they are limited to the AMPs you can run through them and must match the voltage input to the voltage output.
My 12v solar setup that powers my trail cameras 365 days a year. Easy to use and maintain. Never have to worry about dead AA’s again! Thanks for watching and feel free to subscribe if you haven’t yet!
