6.3 Inspection of Connector and Cable

Perform the following preventive maintenance every 6 months:

Check the sealing gels of the junction box for any damage.

Examine the PV module(s) for signs of deterioration. Check all wiring for possible rodent damage,

weathering and that all connections are tight and corrosion free. Check electrical leakage to ground.

If any problem arises, consult a professional solar service provider for suggestions. Caution: observe solar

manufacturers' maintenance instructions for all components used in the system, such as support frames,

charging regulators, inverters, batteries etc.
