14. System Maintenance
The following items are recommended to be checked periodically for the controller to maintain optimum
performance for a long time.
Make sure the airflow around the controller will not be blocked and remove any dirt or debris from the
heat sink.
Take corrective actions in a timely manner in the case of any abnormal malfunction or error alert.
Check the terminals for signs of corrosion, insulation damage, high temperature or burning/discoloration,
enclosure deformation, and if so, promptly repair or replace.
Check for exposed, damaged, insulation performance deteriorated wires, which should be timely repaired
or replaced.
Check for dirt, nesting insects and corrosion, and if so, clean up in time.
Warning:
risk of electric shock! Make sure that all power to the controller is disconnected when performing
the above operations, and then check or operate accordingly! Do not operate without authorization if you
are not a professional.
PV input terminal over voltage
When the voltage at the PV array input terminal is too high, the controller will automatically cut off the PV
input.
PV input reverse polarity protection
When the polarity of the PV array is reversed, the controller will not be damaged. After correcting the
wiring error, it will continue to work properly.
Night reverse-current protection
It prevents the battery from discharging at night via solar cells. Special note: Battery reverse polarity
protection is not available.
