7. Protection
 Battery Over Voltage Protection
When the battery voltage reaches the Over Voltage Disconnect
Voltage(OVD), the controller stops charging the battery to protect the
battery from being overcharged.
 Battery Over Discharge Protection
When the battery voltage reaches the Low Voltage Disconnect
Voltage(LVD), the controller stops discharging the battery to protect the
battery from being over-discharged.
 Overload Protection
The load is switched off after a delay when the load current exceeds 1.25
times the rated current. The user must reduce the load appliance, press the
button, or restart the controller.
 Load Short Circuit Protection
The load is switched off when the load short circuit (≥3 times the rated
current) happens. The user must clear the short circuit faults, press the
button, or restart the controller.
 High Voltage Transients Protection
The controller is protected against small high voltage transients. In
lightning-prone areas, an external lightning arrester is recommended.
8. Troubleshooting
Faults
Possible
reasons
Troubleshooting
The charging LED
turns off during the
daytime when
sunshine falls on PV
modules properly.
PV array
disconnection
Confirm that PV and battery
wire connections are correct
and tight.
No LED indicator
Battery voltage
may be less than
8V
Measure battery voltage with
the multi-meter. Min.8V can
start up the controller.
Charging LED fast
flashes.
Battery over
voltage
Check if the battery voltage is
higher than the OVD, and
disconnect the PV.
LED1 fast flashes.
Battery
over-discharged
The load will recover when the
battery voltage is restored to or
above the LVR (low voltage
reconnect voltage).
Load LED flashes
slowly.
Overload

① Please reduce the number
of electric equipment.
② Press the button or restart
the controller.
Load LED fast
flashes.
Load short circuit
① Check carefully loads
connection, clear the fault.
② Press the button or restart
the controller.
When the load current exceeds 1.25 times, 1.5 times, and 2 times the rated
value, the controller can automatically turn off loads after 60s, 5s, and 1s,
respectively.
10. Disclaimer
This warranty does not apply under the following conditions:
 Damage from improper use or use in an unsuitable environment.
 PV or load current, voltage, or power exceeds the controller's rated value.
 User disassembly or attempted to repair the controller without permission.
 The controller is damaged due to natural elements such as lighting.
 The controller is damaged during transportation and shipment.
