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.
