### Power Cycling your Inverter

| **Step 1: Turning OFF Solar AC Isolator** - This switch will be found adjacent to your inverter. | ![](https://knowledge-base.solarhub.net.au/hs-fs/hubfs/image-png-Sep-08-2025-01-48-17-0989-AM.png?width=670&height=640&name=image-png-Sep-08-2025-01-48-17-0989-AM.png) |

They are typically found adjacent to your inverter. - Once the switches from both step 1 and step 2 are switched off, **wait 5 minutes before continuing.** This will give the system time to reset. |

**Step 3: Complete the Previous Steps in Reverse Order**

- First, turn ON the PV Array Switches.
- Finally, turn ON the Solar AC Isolator.
