series or parallel configuration
I am planning on putting 2 ~300w panels on my boat to charge a 24v battery bank of 4, 6v gc2 batteries in series. The panels I am looking at are about vmp 32.5 and about imp 9.33. I will be using an mppt type controller not yet purchased. 10awg cable from panels to mppt. In parallel connection I should have 32.5v and 18.66 amps. In series I should have 65v and 9.33 amps. Question is what would be more efficient, having the panels in series or parallel. Looking at an mppt controller with150V 20 amp input specs so it should handle either connection setup.
