Recommendations for solar charge/controller
It appears a buddy of mind is going to donate two used 300 watt panels. They are rated at 30 volts with about 8 amps open voltage (he got them for a song - used I should say) We’ve been out in t...

since I have two battery banks (each bank is two 6v gc batts of 210 ah)
I isolate them from each other (one is my house battery bank, one feeds my inverter).
As noted above, one set of batteries is from 2014 - still going strong and the other is from last summer.
The 2014's are in good shape - but they aren't a matched set to the 2022 set.
Can I Switch between each battery bank once bank 1 is recharged to 80%?
What would I have to do in order to make that kind of switch? disconnect the PV panel feed, then switch from bank 1 to bank 2 - removing the load?
In a perfect world, I'd get 4 brand new 6v gc's and do a full charge with my 120volt 3 stage charger until full - and then put them into the trailer - but that seems like a huge waste of capital on the new set of batteries.
thoughts?
