Tesla Powershare installation manual
Quick answer
Tesla Powershare is bidirectional, vehicle-to-home (V2H) backup: a compatible Tesla, currently the Cybertruck, powers your home during an outage through the Powershare home backup hardware, a gateway, and a Wall Connector, all wired into your electrical panel. It must be installed and commissioned by a Tesla Powershare Certified electrician, not plugged in. It backs up the home only while the compatible Tesla is connected, so many homeowners pair it with a Powerwall for always-on backup.For licensed electricians certified for Tesla Powershare, and for Cybertruck owners who want their truck to back up the house during an outage.

What you are installing
This Tesla Powershare installation manual covers how a Tesla Powershare Certified electrician installs vehicle-to-home backup, where a compatible Tesla powers the house during a grid outage. Powershare is wired into the electrical system through dedicated hardware and a gateway; it is not a plug-in feature, and it requires a certified installer.
Powershare turns a compatible Tesla, currently the Cybertruck, into a backup power source for the home. During an outage the gateway islands the house from the grid and the vehicle supplies power through the Powershare home backup hardware and a Wall Connector. Because backup runs only while the vehicle is connected, many homeowners pair Powershare with a Powerwall so the house still has always-on backup when the truck is away.
Before you start
Confirm vehicle and current requirements
Verify the vehicle is Powershare-compatible (currently the Cybertruck) and confirm Tesla's current Powershare hardware and software requirements, which Tesla controls and updates.
Design the backup scope
Decide how much of the home to back up and whether to pair with a Powerwall for always-on backup. This drives the gateway and any panel work.
Permit and panel plan
Pull the electrical permit and plan the gateway and any panel or protected-loads work the backup scope needs.
Certification
Powershare requires a Tesla Powershare Certified installer. Commissioning and warranty depend on it.
Installation, step by step
- 1
Confirm compatibility and scope
Verify the compatible vehicle and the current Powershare requirements, then finalize how much of the home the system will back up.
- 2
Permit and gateway/panel plan
File the electrical permit and lay out the gateway, the Powershare home backup hardware, the Wall Connector, and any protected-loads or panel work.
- 3
Install the gateway and backup hardware
Mount and wire the gateway (which meters the home and islands it from the grid during an outage) and the Powershare home backup equipment into the electrical system.
- 4
Install and wire the Wall Connector
Install the Wall Connector used for the bidirectional connection to the vehicle, on its circuit, per the Wall Connector requirements.
- 5
Commission in Tesla One and configure backup
Commission the system in the Tesla One app, update firmware, pair the vehicle, and configure the backup behavior and reserve.
- 6
Simulated-outage test
Trip the grid connection and confirm the system islands and the connected Tesla powers the intended backed-up loads.
- 7
Inspection and handoff
Pass the electrical inspection and walk the homeowner through how to connect the vehicle for backup and what runs during an outage.
Powershare vs Powerwall for backup
| Aspect | Powershare (V2H) | Powerwall |
|---|---|---|
| Power source | A compatible Tesla (Cybertruck) | A fixed home battery |
| Backup availability | While the vehicle is connected | Always on (stored energy) |
| Best for | Occasional outage backup from the truck | Daily backup and energy shifting |
| Pairing | Often paired with a Powerwall | Can pair with Powershare |
Mistakes we see in the field
These are the errors that fail inspections and callbacks, from real installs. They are the difference between a system that works on day one and one that fails when it matters.
Treating Powershare as plug-and-play
Powershare wires into the panel through a gateway and dedicated hardware and must be commissioned by a certified installer. It is not a plug-in feature of the truck.
Expecting backup when the vehicle is away
Powershare only backs up the home while the compatible Tesla is connected. Homes that need always-on backup should pair it with a Powerwall.
Skipping the islanding test
As with any backup system, a live simulated-outage test is what proves the home actually islands and the vehicle carries the loads.
What to expect: timeline
- On-site install: typically about a day, depending on the gateway, panel work, and whether a Powerwall is installed at the same time.
- Permit issuance varies by jurisdiction.
- Requirements and compatibility are set by Tesla and can change, so confirm current details at design time.

Powershare is Tesla's bidirectional, vehicle-to-home (V2H) backup. A compatible Tesla, currently the Cybertruck, powers your home during a grid outage through the Powershare home backup hardware, a gateway, and a Wall Connector wired into your panel. It must be installed and commissioned by a Tesla Powershare Certified electrician.
The Cybertruck is the compatible vehicle Tesla supports for Powershare today. Tesla controls Powershare compatibility and may expand it, so confirm the current list at design time.
Not exactly. Powershare backs up the home only while the compatible Tesla is connected, so it is great for outage backup when the truck is home. A Powerwall is a fixed battery that provides always-on backup and daily energy shifting. Many homeowners install both, which is why we design them together.
No. Powershare ties into your electrical panel through a gateway and dedicated hardware, requires a permit and inspection, and must be commissioned and registered by a Tesla Powershare Certified installer for safety and warranty. Charge Home Solutions is certified and installs it in all 50 states.
