I now have a 24V x 96Ah Battery Bank: 12 x 12V x 16Ah LiFePO4 batteries wired in a 2S6P configuration.
Also, for this battery bank, I have 6 x 250W Panels: Vmp = 30.3V, Voc = 37.6V and Imp = 8.27A, Isc = 8.85A. My plan is to wire them 3S3P for 90V x 16.5A nominal to the charge controller. This higher voltage and lower current is a good thing for wire size and/or distance to the MPPT... Yes?
Loads will be intermittent, but will be plugged into a 24vdc-120vac 2000W PSWI. There will be a steady load of about 300W and, on occassion, I will be drawing ~ 1800W from that inverter (300w + 1500w). With 85% efficiency and overhead, that's going to be about 98A @ 24vdc. However, it should only last about 15-30 minutes once or twice a day.
Based on the attached Spec Sheets for the batteries and panels, what charge controller and charge profile would you all recommend?
Many Thanks and God Bless!
