7. Protection
Battery Over Voltage Protection
When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage
(OVD), the controller will stop charging the battery to protect the battery from being
over charged to break down.
Battery Over Discharge Protection
When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage
(LVD), the controller will stop discharging the battery to protect the battery from being
over discharged.
Load Overload Protection
Load will be switched off when 1.25 times rated current overload happens. User has to
reduce load appliance, then press the button or repower the controller.
Load Short Circuit Protection
Load will be switched off when load short circuit (≥3 times rated current) happens. User
has to clear short circuit, then press the button or repower the controller.
High Voltage Transients Protection
The controller is protected against small high voltage transients. In lightning prone areas,
additional external suppression is recommended.
8. Troubleshooting
Faults Possible reasons Troubleshooting
LED Charging indicator
turn off during daytime
when sunshine falls on PV
modules properly
PV array
disconnection
Conrm that PV and battery
wire connections are correct
and tight
No LED indicator
Battery voltage
maybe less than 8V
Measure battery voltage with
the multi-meter. Min. 8V can
start upthe controller
Charging status LED indica-
tor Fast ashing
Battery Over Voltage
Check if battery voltage is
higher than OVD, and
disconnect the PV
LED1 Fast ashing
Battery over

When the battery voltage is
restored to or above LVR point
(low voltage reconnect voltage),
the load will recover
Load status LED
indicator slowly ashing
Load over load*
1) Please reduce the number
o f e l e c t r i c e q u i p m e n t s
2) Press the button or repower
the controller
Load status LED
indicator fast ashing
Load short circuit
1) Check carefully loads
connection, clear the fault
2) Press the button or repower
the controller
*When load current reaches 1.25 times, 1.5 times and 2 times more than nominal value,
the controller will automatically turn off loads in 60s, 5s and 1s respectively.
