I have 4-100 watt Renology panels and 2-12 V lithium batteries and a 2000 Watt Renology Inverter.
I am just unsure of what type of controller I should use? Any suggestions?
(I've never done this before but I want to put them on my 6xx10 cargo trailer, but I used to take aircraft engines apart and put them back together so I should be able to do this.)
