Quick answer
To turn on a new Tesla Powerwall 3 system, switch on the PV breaker, all disconnects, the combiner panel (multiple batteries only) and the breakers inside the Tesla Gateway (if you have one), then flip the power switch on the left side of each Powerwall 3. The Tesla "T" logo should settle to a steady white glow. Finish by setting up the Tesla app.
Location: Inside your main electrical panel
Open your main electrical panel and find the breaker labeled PV (this stands for photovoltaic, which is your solar system). Flip this breaker to the ON position. This breaker is what allows electricity to flow to your solar and battery equipment.
Location: Near your main electrical panel and/or near your batteries
The system disconnects are gray boxes with a handle on the front. To turn them on, flip the handle UP with some force. Most homes will have one to three disconnect boxes.
Step 3 is only for systems with multiple Powerwall 3 batteries. Skip this step if you have one battery.
Location: Near your batteries
Look for a smaller gray electrical panel mounted near your batteries. This is called a combiner panel. Open it and flip all breakers inside to the ON position. You will typically see one breaker for each battery.
Step 4 is only for systems with a Tesla Gateway. Skip this step if your system was installed with a Backup Switch (Meter Collar).
Location: Near your batteries or next to your main electrical panel
The Gateway is a white box with the Tesla logo on the front. To open it, release the latch on the right side and swing the door open. Inside, verify that all breakers are switched to ON.
Not sure which you have? Check the installation photos provided at the time of install.
Location: Left side of each Powerwall 3
Find the small plastic cover on the left side of your Powerwall 3. Behind it is a power switch. Flip it to turn the battery ON.
If you have multiple Powerwall 3 units, repeat this step for each battery. If you have Expansion Packs, these do not have a power switch and will turn on automatically.
Note: If the plastic cover is difficult to open, use a flat head screwdriver to gently pry it loose.
Location: On the front glass of the Powerwall
After turning on the power switch, look at the Tesla "T" logo on the front of your Powerwall 3. It should light up white. You may see it flash red or white briefly at first. This is normal. It should settle to a steady white glow.
Note: Expansion Packs do not have a light, so only your Powerwall 3 unit(s) will illuminate.
The Tesla app lets you monitor your system's performance from your phone.
