I'm looking to install 10 x 320W panels on my RV. They have a Voc of 45.6V and a Isc of 9.1A. I will have a large 24V lithium LiFePO4 battery. My question is...which charge control(s) would work best for this system. My thoughts are 2 x 250/100's with 5 panels on each controller. Just not sure if I can use smaller units with a 24V system.
