Maintenance
The following inspections and maintenance tasks are recommended at least twice per year for optimal
performance:
1. Ensure there are no obstructions to the airflow around the inverter. Clear any dirt and fragments
on the heat sink.
2. Check all exposed wires to ensure insulation is not damaged by sun exposure, frictional wear,
dryness, insects, rodents, etc.
3. Verify that the indicator display is consistent with the actual operation.
4. Confirm that terminals show no signs of corrosion, insulation damage, high temperature,
burning, discoloration, and tighten terminal screws to the suggested torque.
5. Promptly clear any dirt, nesting insects, and corrosion.
Possible reasons
The DC input voltage is
too low
The DC input voltage is
too high
Overload
Load short-circuit
Inverter over-
temperature
Troubleshooting
Check whether the DC input
voltage is lower than 10.8V
with a multi-meter.
The inverter resumes work
after adjusting the input
voltage.
Check whether the DC input
voltage is higher than 16V with
a multi-meter.
The inverter resumes work
after adjusting the input
voltage
Check whether the AC load's
power is within the inverter's
rated power; clear the
overload faults, and restart the
inverter.
Check the load connection
carefully.
Clear the short circuit faults
and restart the inverter.
Improve the ventilation
situation and bring the
ambient temperature down. It
is recommended to restart the
inverter after the temperature
drops. If the fault cannot be
cleared after performing the
above operations, decrease the
rated power.
