Currently I am running 12 180w 39.8Voc(V) 5.48Imp(A) flexible solar panels on my catamaran. They are configured in series of two for 79.8voc and then paralleled in groups of six for 32.88amps. These charge my 16 series 400ah Winston cells along with a couple dc generators, and two shore chargers. I run all the charging sources through a http://www.colemanair.us/shared/Dive...VA_CURRENT.PDF
This works quite well enough and is very robust as a standard charge controller so neither pwm or mppt. I am wondering though if I wanted to try a mppt controller which might be suitable and how to configure my panels? I was thinking of trying them series connected in 3 for 119.4Voc and 21.92 amps and if I would get a better charge rate from them.
So far the boat has had a number of test runs and performs as expected moving the catamaran around for only 30 amps upriver against current. Some videos of the times it was out on the water here https://www.youtube.com/channel/UC6B...cixqeoS1XlLYww
I did have all the panels wired into a combiner box on the boat behind the radar but I'm not big on that idea. I then discovered MC-4 In-line fuse holders so will be purchasing six of those and doing away with the combiner box and cleaning up the octopus there before it enters the cabin roof.
I have been looking at http://www.epsolarpv.com/en/uploads/...5121966928.pdf as a suitable candidate but how would I wire the panels to work with this controller?
Thanks for any help and letting me post.
