Based upon what I learned here, I've now removed the six amorphous Harbor Freight panels, and installed a new Outback FM60 MPPT for the decent panels. They were installed wired in parallel and I decided to leave it that way for now. I didn't really want to cut into the splices etc.
I installed a new Morningstar 25 amp PWM for the mismatched solar panels.
I'm amazed to watch the numbers on the display of the FM60. There's a world of stuff going on in there. I switched on the freezer
mongo-compressor today, it draws 30 amps , and watched the Outback putting 20.8 back into the battery pack by itself. I wasn't monitoring the PWM or the wind
, but I think it would have kept up with the compressor
load all together. Normally I wouldn't do that. I would only run the big compressor
when both engines were on and both 80 amp alternators on line.
Anyhow, I just wanted to say thanks to everyone who took the time to answer my newbie questions. The education I got on this forum gave me the confidence to order and import
, sight unseen, a thousand bucks worth of controllers, wires, switches, circuit breakers etc. and install them myself.
I shut the shore power
off two days ago.
