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.

4.3 Maintenance

The following inspections and maintenance tasks are recommended at least
two times per year for best controller performance.

Make sure controller firmly installed in a clean and dry ambient.

Make sure no block on air-flow around the controller. Clear up any dirt and
fragments on radiator.
Possible reasons
PV array disconnection
Battery voltage is lower
than 9V
Battery voltage higher
than over voltage
disconnect voltage(OVD)
Battery under voltage
Battery over temperature

Troubleshooting
Confirm that PV and battery wire
connections are correct and tight
Please check the voltage of
battery. At least 9V voltage to
activate the controller
Check if the battery voltage is too
high, and disconnect the solar
module
Load output is normal, charging
LED indicator will return to green
automatically when fully charged
The controller will cut off the
output automatically, LED
indicator will return to green
