Hi, I purchased a couple of large solar panels a couple of years ago and I'm about to hook them up.
I've set them up on a temporary basis to charge my battery on my vehicle and run some things with a lead acid battery.
I just ordered some lithium iron phosphate cells and a bms from battery hookup to do this on the cheap.
I've watched hundreds of videos from other solar guys online, but I don't feel you really learn it until you do it yourself.
