INSTALLATION MANUAL
CRYSTALLINE SOLAR MODULES
electronically connected to earth and therefore can be operated together with either galvanically isolated
(with transformer) and transformerless inverters. However, if the system is located in a hot, humid climate and
the maximum voltage is greater than 600Vdc then galvanically isolated inverters incorporating a transformer
must be used and the negative pole of the array must be connected to earth.

MAINTENANCE AND CARE
A well designed solar system requires minimal maintenance; however, system performance and reliability can
be improved by taking some simple steps.
•
Maintenance should be carried out at least once a year by trained personnel.
•
Trim any vegetation which may shade the solar array thus impacting performance.
•
Check that mounting hardware is properly tightened.
•
Inspect all cables to verify that connections are tight; the cables are protected from direct sunlight
and sited away from areas of water collection.
•
Check that all string fuses in each non/earthed pole are operating.
•
In the event that the solar modules need to be cleaned then clean the module use a soft cloth
together with a mild detergent and clean water. Take care to avoid severe thermal shocks which
might damage the module by cleaning modules with water which has a similar temperature to the
modules being cleaned.
•
The back surface of the module normally does not need to be cleaned but, in the event this is
deemed necessary, avoid the use of any sharp projects that might damage the penetrating substrate
material.
Sapphire Solar can provide an annual inspection and maintenance service at an additional cost, please contact

SHUTDOWN AND START-UP OF SYSTEM
For any electrical maintenance, the PV system must first be shut down. Improper maintenance can cause
lethal electric shock and/or burns.
SHUTDOWN OF SYSTEM
1.
Check the shutdown procedure on the main switchboard.
2.
Turn off the Solar Array AC Main Switch located in the switchboard and/or next to the inverter.
3.
Turn off the Solar Array DC Main Switch located next to the inverter. If you have two DC isolators turn
both off.
4.
Turn off the DC Isolator located on the underside of the inverter
TO RESTART THE SYSTEM
1.
Turn on the DC Isolator located on the underside of the inverter
