My charge controller is limiting current. It seems to be skipping absorption mode entirely and has already entered float mode at 10:00 am. As a result, last night my voltage dropped below 12 volts on a 300 ah LiFePO4 battery bank. The system charges fine when using the Victron Energy Blue Smart IP65 12-Volt 15 amp Battery Charger from the grid. My Victron charger is showing 13.56 amps, nowhere near absorption voltage, so something is definitely up with the controller. I've checked the panels and I'm getting correct current there, the controller is just limiting it.
System: 640 watts of solar, Rover 60 controller, 3 100 ah Battle Born batteries.
Any help is greatly appreciated.
