times per year for best performance.

Make sure controller firmly installed in a clean and dry ambient.

Make sure no block on air-flow around the controller. Clear up any dirt and
fragments on heat sink.

Check all the naked wires to make sure insulation is not damaged for sun
exposure, 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.

troubleshooting or error indication .Take corrective action if necessary.

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, tighten terminal screws to the suggested
torque.

Clear up dirt, nesting insects and corrosion in time.

Check and confirm that lightning arrester is in good condition. Replace a new
