Hello! I did look through previous posts first before asking and didn't see anything related to what I have. To begin let me reiterate, I'm very new and very excited to put together a learning kit so my dad and myself can eventually work up to much larger projects. I recently came across 6 solar panels for a very good deal. They are SS270P-72 panels. Rated output is 270 watts, 44.4 volts and 7.6 amps. I tested each one about an hour ago in direct sunlight and got 41 volts and 5 amps from each one.
What I'm looking for is advice to keep cost down since this is my first project. I honestly have no idea what my end goal is other than learning so please be patient with me. I'm looking for info on how I should wire them, how many in the series and how many in parallel. I'm thinking 3s2p and getting a 150v/20a SCC or go 2s3p and getting a 100v/20a SCC. I want to still use 10 gauge wire and I think I can with either configuration. Is one preferred over the other for charging batteries? Do I want/need to go with 12v or 24v?
I certainly want to use lithium iron phosphate batteries over lead acid eventually. I have one of those batteries in my RV and after studying them they are certainly superior. I'll buy those later as they are super expensive and I kinda want to build my own from cells after watching a ton of videos and reading up on it.
I greatly appreciate any advice yall can give and if you need more details please let me know and thanks in advance!!
Pics attached are the label from the panels and them loaded up ready for the trip this weekend!
