Make sure that the inverter is disconnected from all power sources and that the capacitors are
fully discharged before carrying out any checks or operations to avoid the risk of electric shock.
8.2、Maintenance
To maintain optimum and long-lasting working performance, we recommend that the following items are
checked twice a year.
1. Ensure that the airflow around the inverter is not blocked and remove any dirt or debris from the radiator.
2. Check that all exposed conductors are not damaged by sunlight, friction with other surrounding objects,
dry rot, insect or rodent damage, etc. The conductors need to be repaired or replaced if necessary.
3. Verify that the indications and displays are consistent with the operation of the equipment, note any
faults or incorrect displays and take corrective action if necessary.
4. Check all terminals for signs of corrosion, insulation damage, high temperatures or burning/discolouration
and tighten terminal screws.
5. Check for dirt, nesting insects and corrosion, clean as required，Clean the insect screen regularly.
6. If the lightning arrester has failed, replace the failed arrester in time to prevent lightning damage to the
inverter or other equipment of the user.
The Company shall not be liable for damage caused by :
1. Damage caused by improper use or use in a wrong location.
2. Photovoltaic modules with an open circuit voltage exceeding the maximum permissible voltage.
3. Damage caused by the operating temperature exceeding the restricted operating temperature range
4. Dismantling and repair of the inverter by unauthorised persons.
5. Damage caused by force majeure: damage during transport or handling of the inverter.
