Shut down solar systems for power restoration safety

Published: 30 Mar 2017 4:41pm

Ergon Energy  is urging people in the disaster area caused by Tropical Cyclone Debbie to check that their Solar PV systems are shut down.

Customer Delivery Manager Chester Brodie said any Solar PV systems that were not shut down prior to the extreme weather event could now present a significant danger.

“If the solar system wasn’t shut down before the event then it is potentially sending electricity into our damaged network,” Mr Brodie said.

“Even though grid-connected solar PV systems cannot supply the home when the network is not operational, they can continue to generate direct current (DC) power.”

A general shutdown procedure is as follows:

1. Turn off the inverter AC mains isolator, usually found in the meter box.

2. Turn off the PV array isolator, usually found next to the inverter.

“If you are unsure of the shutdown procedure, contact the manufacturer or installer,” Mr Brodie said.

“It is critical to remember that solar panels and their cables should always be treated as if they are live.”

“Please do not access the roof,” Mr Brodie said. “Safety should always be your number one priority."

“Customers should not attempt to reconnect solar PV systems after severe storms or roof damage, as their roof may be electrified.”
