7. System Maintenance
In order to maintain optimal long-lasting performance, it is recommended that the
following items be checked twice a year.
1. Confirm that the airflow around the all-in-one machine will not be blocked and remove
any dirt or debris from the head sink.
2. Check all exposed wires for damage of insulation caused by sunlight, friction with other
objects around, dry rot, insect or rodent biting, etc., and repair or replace the wires if
necessary.
3. Verify if the indications and displays are consistent with the operation of the equipment,
be aware of any faults or incorrect displays, and take corrective actions if necessary.
4. Check all terminals for signs of corrosion, insulation damage, high temperature or
burning/ discoloration and tighten terminal screws.
5. Check for dirt, nesting insects and corrosion and clean up as required.
6. If the lightning arrester has failed, replace it in time to prevent lightning damage to the
all-in-one machine or even other equipment of the user.
Warning: risk of electric shock! Make sure all power supplies are disconnected from the all-in-
one machine and the capacitor is completely discharged before performing any checks or
operations!
The Company shall not be liable for any damage caused by:
Improper use or use in an unsuitable place.
Open circuit voltage of the PV module exceeding the maximum allowable voltage of
145V.
