I am upgrading my old offgrid 12V lead acid system to a 24V LiFePo4. My old system ran on a single 190W solar panel. I have purchased 3 x 440W panels (49.9V OC and 9.65A Max) and and they will be hooked up to an MPP All-in-One Inverter/Charger/Charge Controller. I was going to hook up all 4 panels (even though I don't need all the power) by putting 2 of the 440W panels in parallel and the 190W and 440W in parallel and then hook the two banks up in series. It looks like this is a bad idea. Should I just sell the 190W and then put the remaining 3 x 440W panels in series?
