Am I crazy? I want to hook up my 2 new Solar Panels [ aprox. 12" by 36"] to used car batteries.Will this work?

I have 2 solar panels from Canadian tire, about 12″ by 36″, plus an inverter [rated up to [?] 800 watts [?]. I have access to used automotive batteries. I want to use the solar panels to charge the ‘decent’ used batteries, then power things like fans, lights, maybe a pump? I know car batteries are good for quick bursts of power, whereas a deep cycle batteries are good for long slow draws of power. Is there a way to ‘wire’ or ‘hook up’ the batteries so that I will maximize their usefulness? [ in 'series' or 'parallel']. Will the solar panels have less ‘power’ to give to the batteries, if I have more batteries? [ Say, 4 batteries vs. 10]. Any suggestions are appreciated!

if you’re going to power stuff like fans, lights, etc. you’re probably going to want 110. so you will need to:

- hook up the solar panels to provide 110 volts.
- hook up the batteries to provide 110 volts.
- make sure that everything you attach to them can use direct current.

you’ll need to determine how much current you’ll draw over a day, and make sure that you generate at least that much.
and store that much.

however, what are you going to do when you have no sun, and a week of rain?
good luck.
