I have Sol-Ark 5K inverter, 22 x 230W (CS6P-230P panels). Also I bought Midnight Solar MNPV6 DC Combiner Box with 4 15amp DC breakers. From what I understand this box is configured as a junction box for 4 strings. Each string would be wired individually to 15amp DC breaker and wired via 146' cable lenghts to my inverter. I have a 4" conduit installed with the string in the trench ready for the cable pull. My ground mount is in place and I'm getting ready to install my panels. When I bought my Sol-Ark I had my 22 panels already purchased and based on that I was told to configure my panels in 2 x 6 and 2 x 5 strings (I am planning to ad 2 more panels to make this 4 x 6 panels in the future). Initially I was told to buy tec #10 4C wire to connect my 4 strings to Sol-Ark inverter. I am having trouble understanding how this would work. That is one of the main reasons I did not buy the cable yet. I've discussed this with a friend (electrician) and we've agreed that running 4 separate cables might be the best option. 4 x 10\2, 4 x 12\2, 14\2 ??? I understand that I'm running hight voltage DC from the my array to Sol-Ark, but my Imp is only 7.78 amps per string. I would appreciate any coments.
