hey , been reading a lot of threads here and on other forums the past couple weeks, and
it seems like you guys really know what you're talking about/ so maybe you can help clear some
confusion or doubts that I have about the system I'm setting up
I read somewhere that an Ideal balance would have the solar panels generating 5-13% of
the batteries capacity rating, with a DOD somewhere between 20-50%
something like using one kwh a day with-
(four) 100 watt panels @ ~5 amps each
(one) 30A PWM charge controller
(two) Sam's club 6v 215Ah GC2 batteries
the batteries seem to be a limiting factor here for me. In the area here, of the batteries or
brands I've heard recommended, I can only find:
Trojan SCS 12v 130Ah for $250
Sam's club 6v 215Ah for $89 each
The guy at this place Battery Post also recommended a Trojan 12v 105 Ah, though i'm not
sure about the price, so i'm gonna call tomorrow
_____________________________________________
my goals are, at the core, to run at least one 100 watt water pump for half an hour, and a
300 watt electric rice cooker for about half an hour. I'd possibly want to run another water
pump also, with similar wattage.
right now I actually have two 100 watt panels, and I'd much rather use just these two, or even
just one panel, and a lower capacity battery, to save $300 on the panels that I don't have.
if the Sam's club GC2's are cheaper and higher capacity though, and I need to buy more panels
to keep a good balance, I definitely want to consider it. I can always find and plan on more things
to power.
I'm looking for suggestions on how to acheive these goals, using any variation really that you
can think of. I'd love to do two systems of a 100 watt panel each, but I don't know if that would
make sense given what batteries are available or advisable. As far as batteries go, I have access
to Walmart, Sam's club, Costco, and a few places like Autozone.
so you probably know something that I don't/ how could I achieve these goals without buying
more stuff than I need to?
