RE: Living Off The Grid Tips & Tricks #2: How to charge your phone and USB devices on 12V, 24V and 48V solar power systems
Thanks for the breakdown. I have a little solar panel/battery backup thing I bought several months ago, and I wish I had understood more at the time. The solar is largely useless as out takes OVER A MONTH to fill the battery by itself. But even when I treat it as just a backup battery and charge it in the wall, I have since discovered my phone drains so fast/it charges so slow, that with my phone in sleep mode, it doesn't charge the phone fast enough and the phone will still drain out and die. Ugggggh. It will charge my Kindle, though. LOL You live, you learn, I guess!
I think everybody fully off-grid went through this learning period, nothing to worry about. Anything less than 2 solid 150Ah batteries and a total of 150W panels is playing and learning time.
