Hi all, I have not been able to understand why my battery bank capacity is so much less than it should theoretically be. I have 12 six-volt 230 AH flooded lead acid deep cycle golf cart batteries arranged in three sets of 4 in series giving 24 volts. These batteries are only one year old. In...

I'm in need of some expert advice: I am installing four 370 watt 35 Vmp 10.7 amp panels and was planning to wire them 2s2p using a single pair of 6 awg wires. So about 70 volts and 22 amps to go the 25 feet to the controller (Midnite Solar max 150 volts and 60 amps). But my friend says that...

The 4 panels I want to wire in parallel are 35 volts and about 10 amps output. My run to the MPPT controller is about 20 feet, so I would like to combine two of the panels and transition from 10awg to 8awg. But I can't find any mc4 connectors that make this size change. How should this be done?

Question from a relatively new solar guy. I want to double my panels from 4 to 8, and the panels will have different voltage and amps. I plan to get a second MPPT controller for the second 4 panels and feed the 24 volt output into the same 690 AH battery bank. Will the two controllers interfere...
