Instructions
It is recommended to check the following items to keep the long-term high performance of the
System:

Check whether the insulation layers of all exposed cables have been damaged because
of sunlight, contact with objects around the cable, dry rot, or destruction by insects or rats.
If damaged, maintain or replace the cable immediately.

Check whether the terminal blocks have signs of corrosion, insulation damage, burning
or discoloration, and whether they are tightened.

Check whether there is dirt, nesting insect, or corrosion. If yes, clean them in time.

In areas with special weather conditions, it is recommended to do necessary
maintenance to keep the System work properly. For dry, dusty and rainless areas, dust
on the System will influence its power generation efficiency. For cold, snowy, and frozen
areas, snow and ice covered on the System will lead to decline in power generated and
even failure of the System. You need to clean the dust regularly, and clean up the snow
in time.

Check regularly the plants around the System. If any plant has grown to shade the
System, clean it in time.

Replace the batteries of decreased performance every 3–5 years, depending on the
actual conditions of the battery.
