If your solar power inverter is more than 3 metres away from your switchboard, you must locate the switch marked, solar AC isolator. This will be located next to your inverter. If your inverter and switchboard are within 3 metres of each other, disregard this step.
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 switched off. All lights and screen displays will be dead. Keep the system off for a minimum of five minutes.
