Go to your inverter. Locate the AC ISOLATOR main switch and turn the switch to the OFF position.
Alternatively go to your fuse board and 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.
Your inverter may have a switch marked INVERTER ISOLATOR. If it does, flick this switch to the OFF position. If you cannot locate this switch on your inverter, skip this step.
Your solar PV system should now be completely off. All lights and screen displays will be dead. Keep the system off for a minimum of five minutes.
To re-start your system, follow this guide in reverse order. Ie: DC ISOLATOR on first, followed by AC ISOLATOR, followed by your solar supply main switch.
