I have just purchased an 80amp MPPT 250V Growatt SCC. I plan on purchasing 2 365 Rich Solar 335W panels which I want to use to charge separate 48V 304AH LifePO4 banks for powering electric boat motors (no inverter involved) . Would it be possible (and safe) to use a A/B battery switch to manually chose which bank to charge? Thanks for any guidance.
