EPEVER Solar Charge Controller: “Load + fault — short circuit”
danger RV solar charge controller error codes
What it means
The load and fault indicators blinking signal a load-side short circuit. When load current reaches roughly four times the rated load current, the controller cuts the load output to protect itself.
Most likely causes
- Short circuit or pinched/chafed wire on the load output wiring most likely
- Faulty appliance/device connected to the load terminals common
- Water ingress or corrosion bridging the load terminals less common
Safe checks you can do yourself
- Disconnect all loads, then inspect load wiring for damaged insulation, pinches, or terminals touching
- Check each connected device individually for an internal fault before reconnecting
- Look for moisture/corrosion at the load terminals
How to reset / clear Load + fault — short circuit
- Find and clear the short before re-energizing
- The output auto-retries five times (after about 5, 10, 15, 20, 25 s); to restart the recovery, press the Load button, restart the controller, or wait for a night-to-day transition (night longer than ~3 hours)
When to call a technician
If no external short can be found yet the controller keeps tripping load short-circuit, the controller's load output may be faulty — have it checked.
Applies to
EPEVER Triron N series · EPEVER Tracer-AN series · EPEVER Tracer-BN/BP series
