RV solar charge controller error codes
MPPT/PWM solar charge controllers manage charging from RV solar panels. Errors flag battery voltage/temperature, panel over-voltage and controller overheating.

The battery indicator slowly flashing red signals a battery temperature fault: w… Battery red solid — over-discharged
A steady red battery indicator means the battery is over-discharged: voltage has… Green LED fast flash — battery
The battery-status indicator flashing green at about 4 Hz means battery over-vol… Green LED fast flash — charging
The PV/charging indicator flashing green at about 4 times per second signals PV … Load + fault — short circuit
The load and fault indicators blinking signal a load-side short circuit. When lo… Load blinking — overload
The load indicator blinking (load off) signals a load overload: connected load c… No charge in daylight
Two related no-charge indications: the green PV/charging indicator OFF while the…
