Hello everyone!
I live in the US Virgin Islands in the Caribbean. Still no grid power where I live since Hurricane Maria so I am setting up my little cabin to be off grid. I have purchased (4) 270W LG solar panels at 28.8 V and 6.8A. I plan to use the Midnite Kid charge controller to charge a 24V battery system using 4 Trojan T-105RE batteries. The main loads on the system will be 4 - Caframo 24V fans, 4 - 24V lights and a 24V solar refrigerator from Eco Solar Cool.
My main question is wiring my solar panels in series or parallel or a combination of both. I was leaning towards series to have maximum voltage and minimize wire size. However, when I looked at the Midnite Kid documentation, they show a 4 panel configuration at 24V with two panels each wired in series and the two strings wired in parallel. See attachment. If I went this route then I would need to buy a combiner box which seems unnecessary and wouldn't be needed if they were all in series.
Can someone please advise if following Midnite's wiring diagram for my panels is better than wiring them all in series and going straight to a circuit breaker disconnect box upstream of charge controller?
I really appreciate the help and have enjoyed this forum and its wealth of information.
Warm vibes from the Caribbean!
