24V systerm. Panels ~72V was being ran by midclassic and FLA Trojans.
Just upgraded/installed Blue Solar 100/50 and LiFePo4 batteries
Set switch to position 7 for lifepo4, leds blink properly to indicate setting.
Then flashes error cofe of Absorb and Float to indicate a "Charger or PV over-voltage" error.
Voltage at the screws of the Blue Solar is 72V on the panels and 24.9 on the batteries.
Side note, cant get CC to connect to the app. Not sure why. It does have bluetooth correct? it is called Blue solar.
