Power Cycling your SolarEdge + Powerwall 1 System

Article Contents

Powerwall 1 Overview

The Powerwall 1 was Tesla’s first iteration of its home battery system. Although it has since been upgraded and discontinued, a considerable number are still in operation today. Unlike other batteries, the Powerwall 1 does not feature built-in ON/OFF capabilities. Instead, it is designed to function as part of a system integrated with your inverter with the addition of a DC isolator integrated for the battery. By power cycling your inverter, you also power cycle the battery. To troubleshoot a Tesla Powerwall 1, follow the instructions provided below or those supplied by the manufacturer to power cycle your inverter.

Reposit Users

For homes that have a Reposit Power system, follow this step first. If not, proceed with turning OFF your inverter.

Step 1: Opening your Reposit

Squeeze on the two clamps on the right side of the box and pull open the front panel.

Step 2: Switch off the system

Flick the cubicle isolator switch to the OFF position (1).
Once you have completed this step, continue with the rest of the inverter power cycling before completing step 3. Turning back on your Reposit will be the last step.

Turning OFF your Inverter

Directions for system shutdown can also be found on the front of your inverter.

Step 1: Turn OFF the Inverter’s Toggle Switch

Locate the ON/OFF/P toggle switch on your inverter.
Flick the switch to the ‘OFF’ position.
Once this has been switched off, wait at least 5 minutes before continuing to the next step. This gives the system time drop below 50V (a safe voltage level).

Step 2: Turn OFF the Inverter’s AC

Locate your AC isolator switch. Depending on the model of inverter, your AC isolator switch is most commonly adjacent to your inverter.
Move the switch into the ‘OFF’ position.
If your inverter is within 3m of your main switchboard, your inverter won’t have an AC isolator switch. To turn off the AC, go to the main switchboard, and turn off the ‘main switch inverter supply’. This switch should be clearly labelled alongside the rest of your home’s power supply switches.

Step 3: Turn OFF the Inverter’s DC

Your inverter’s DC isolator switch is located on the front of your inverter. The DC isolator switch is incorporated with the HD wave inverter design. For other models of the SolarEdge inverter, it will be located adjacent to your inverter. Along with this DC isolator, there will be secondary DC isolator for the battery. This will also be located adjacent to your inverter.
Turn your switches to the ‘OFF’ position. This step may be a bit tricky as the switch may show resistance and require more force to turn off. Keep turning until it clicks.
Wait for 5 minutes for turning everything back ON.

Turning ON your Inverter

Follow all the previous inverter steps in reverse order.

Step 1: Turn ON the Inverter’s DC

Turn your switches to the ‘ON’ position.

Step 2: Turn ON the Inverter’s AC

Move the switch into the ‘ON’ position.
If no AC isolator switch is present, turn on the ‘main switch inverter supply’.

Step 3: Turn ON the Inverter’s Toggle Switch

Flick the switch to the ‘OFF’ position.
Once this has been switched off, you should see LED lights begin to flash. This represents the system restarting.
Wait at least a minute for the LED lights to stop flashing and become a constant light. This indicates that the inverter is now producing power again.

Step 4: Turn back ON Reposit (IF APPLICABLE)

Flick the same switch back ON.
When rebooting, the LED located on the Reposit Controller (2) will first be red and it last for 1-2 minutes normally. Then the red LED will go off. A blue-ish white light will be on in a few seconds after that.
When the Reposit controller is operating, the LED will be blue-ish white.
If the red light stays on for a long time, that means the Reposit controller might be in faulty mode. Try rebooting it. If the red light doesn't turn blue-ish white after rebooting, the Reposit controller could be faulty then.
