Ensure that all electrical connections comply with local electrical standards.
Obtain approval from the local power supply department before using the SUN2000 to
generate electricity in grid-tied mode.
Ensure that the cables to the solar power system are properly connected and insulated
and meet specifications. Confirm that the insulation resistance between the ground and

the first power-on of the SUN2000. Incorrect settings may affect the SUN2000 operation
and cause the SUN2000 to conflict with local certifications.

maintenance site.
Rectify any faults that may compromise the SUN2000 security performance before
restarting the SUN2000.
