6 FAQs about [Photovoltaic inverter procedures]

Which inverter is required for a combined PV and storage system?

Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).

Do you need an electrician to test a PV inverter?

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. For inverters with PV panels connected, the tests must be conducted at a time of day when weather conditions allow the PV system to be producing a minimum power output.

How do you turn off a solar inverter?

Locate the AC ISOLATOR main switch and turn the switch to the OFF position. Alternatively, go to your fuse board, locate the PV ARRAY main switch, and flick to the OFF position. At the inverter, locate the DC ISOLATOR and turn to the OFF position. If there is a battery fitted, locate the 2nd DC ISOLATOR, and turn to the OFF position.

Where should a PV inverter be installed?

An inverter supplied from a PV array must preferably be installed in a dedicated circuit in which: no current-using equipment is connected, and no provision is made for the connection of current-using equipment, and no socket-outlets are permitted. An inverter must not be connected by means of a plug with contacts which may be live when exposed.

What happens if a PV inverter fails?

An insulation failure in a PV system circuit presents dual hazards of fire and lethal electric shock. Insulation failures can also impact the energy production of the system by tripping the GFDI (ground fault detection and interruption) device and taking the inverter offline.

What happens if a micro-inverter is not used in a PV system?

If micro-inverters are not used, the PV system will have both AC and DC components. The DC system determines system power capacity and energy production, whereas the inverter and the AC system has the greatest impact on system reliability.
