4 FAQs about Photovoltaic inverter maiden flight test

When should a PV system be tested?

The tests must be conducted at a time of day when the prevailing weather conditions allow the PV system to be producing a minimum power output. This must be greater than 20 per cent of the rated output of the PV array or the inverter – whichever is less. If there is more than one inverter, you must use separate forms for each.

How often should a PV inverter be tested?

The PV inverters must be tested to ensure the safety of personnel who work on the ActewAGL network, such as powerlines and underground cables, and to the general public. The inverter must be tested at least once every five years to ensure that safety is not compromised for ActewAGL personnel and the public.

Do I need an electrician to test my PV system?

Warning: Carrying out these tests involves working with live DC and AC voltages. The testing must only be carried out by an ACT licensed electrician who possesses a Clean Energy Council (CEC) accreditation. The tests must be conducted at a time of day when the prevailing weather conditions allow the PV system to be producing a minimum power output.

How do you test a solar inverter?

A current probe is to be placed on the installation side of the main switch to determine when the inverter recommences exporting power. The DC supply from the solar array is to remain connected to the inverter for the duration of this test. The tester must make copies of the test record.
