So if I'm doing the math correctly, his 11,600 Watt-hour battery bank (assuming a 12 volt system) has 966 amps to draw from. Also assuming he will not take that below 50%, he has 483 amps to use.
Nobody would try to charge a bank that size with a 115 watt panel, so of course it doesn't "even move the needle". The system I am currently installing (5 - 245 watt panels) would put 100 amps into the bank per hour (perfect conditions of course) and make it possible to recharge the battery bank in 5 hours.
Of have I missed something?
