Maintenance
1)
The following inspections and maintenance tasks are recommended at least two times per year for the
best performance.
Make sure the inverter/charger is firmly installed in a clean and dry ambient.
Make sure no block on airflow around the inverter/charger. Clear up any dirt and fragments on the radiator.
Check all the naked wires to ensure insulation is not damaged for serious solarization, frictional wear,
dryness, insects or rats, etc. Repair or replace some wires if necessary.
Tighten all the terminals. Inspect for loose, broken, or burnt wire connections.
Check and confirm that LED or LCD is consistent with the actual operating. Pay attention to any
troubleshooting or error indication. Then, take the necessary corrective action.
Confirm that all the system components are ground connected tightly and correctly.
Confirm that all the terminals have no corrosion, insulation damaged, high temperature, or burnt/discolored
sign. Then, tighten terminal screws to the suggested torque.
Check for dirt, nesting insects, and corrosion. If so, clear up in time.
Check and confirm the lightning arrester is in good condition. Replace a new one in time to avoid damaging
the inverter/charger and even other equipment.
WARNING
Risk of electric shock! Ensure that all the power is turned off before the above operations,
and then follow the corresponding inspections and operations.
