
Load Over Load
Load will be switched off when 1.05 times rated current overload happens.
Controller will automatically attempt to reconnect load for 5 times. If overload
protection still exist after controller‘s 5 times attempts, user have to reduce
load appliance, then press the button or repower the controller or wait for one
night-day cycle (night time>3 hours) or press button.

Load Short Circuit
Load will be switched off when load short circuit (
≥4 times rated current)
happens. Controller will automatically attempt to reconnect load for 5 times. If
short circuit protection still exist after controller‘s 5 times attempts, user have to
clear short circuit ,then restart the controller or wait for one night-day cycle
(night time>3 hours) or press button.

Damaged Remote Temperature Sensor
If the temperature sensor is short-circuited or damaged, the controller will be
charging or discharging at the default temperature 25
℃
to prevent the battery
damaged from overcharging or over discharged.

Controller Overheating
If the temperature of the controller heat sinks exceeds 85
℃
, the controller will
automatically start the overheating protection and recover below 75
℃
.

High Voltage Transients
PV is protected against small high voltage surge. In lightning prone areas,
additional external suppression is recommended.
CAUTION: Faults will be cleared every day, so the faults which
aren‘t caused by hardware can be solved intelligently.
5.2 Troubleshooting
Faults Possible reasons Troubleshooting
