Tesla Wall Charger
Wall Connector is the most convenient charging solution for houses, apartments, hospitality properties and workplaces.
With up to 71 km of range added per hour of charging, multiple power settings, 7.3m length and a versatile indoor/outdoor design, Wall Connector provides unparalleled convenience.
Wall Connectors can power-share to maximize existing electrical capacity, automatically distributing power to charge multiple cars simultaneously.
POWER SHARING OVERVIEW
What does power sharing do?
By intelligently managing available power on a given circuit, power sharing allows a single electrical circuit to support multiple Gen 3 Wall Connectors while still ensuring your electric vehicles get a sufficient charge.
​
How does it work?
Power sharing manages the total amount of power used by multiple Gen 3 Wall Connectors via Wi-Fi between connected units. For a given power sharing system, there will always be one Gen 3 Wall Connector that is considered the “leader." Any additional Gen 3 Wall Connectors are considered “followers." It is the responsibility of the leader to control how much electrical current each follower is allocated at any given time.
Why should you care about power sharing as a Gen 3 Wall Connector owner?
This functionality is ideal for households that need to charge more than one electric vehicle at the same time, but may not have enough power for multiple electrical circuits.

A job done correctly. It improved the home’s efficiency, offering more functionality, enhanced space-saving, and ensured less future maintenance requirements. This was one of my most challenging and enjoyable projects, because it was a lengthy process in which the client was involved with every step. Check out the end result for yourself!
Frequently Asked Questions
Can I use power sharing between Tesla Wall Connectors and another EV charging connector?
No. Power sharing is only compatible between Tesla Gen 3 Wall Connectors.
Can I connect Gen 2 and Gen 3 Wall Connectors together in a power sharing network?
No. This configuration is not currently available.
Is an internet connection and/or Wi-Fi network required to use power sharing?
No. Power sharing can be set up completely offline with no external connectivity. A Wi-Fi connection is required to receive firmware updates, new features and advanced support.
The charge current available to my car keeps changing - is this normal?
Yes. Power sharing works by allowing all available current to be distributed as efficiently as possible based on the actual current drawn by each vehicle.
Troubleshooting
If you are experiencing issues with a power sharing network, the most common issue is a loss of communication between the leader and follower units. This can be due to a loss of power (a follower Wall Connector has been removed, the circuit breaker is open, etc.) or a loss of communication over Wi-Fi.
When a Wall Connector in a power sharing network is not available, the overall network will operate at reduced rates to ensure it does not exceed the current limit. To resolve loss of communication, connect to the leader and follow the set-up procedure. This will indicate which units in the network are unavailable.
Typical steps to resolve communication issues:
Confirm all Wall Connectors are powered on.
If your Wall Connectors are connected to the home Wi-Fi, then ensure that the signal strength between participating Wall Connectors and the home Wi-Fi network is adequate. This can be verified by looking at signal strength in the configuration wizard of the leader.
This is important for power sharing stability since any reconnection attempts or channel hops will momentarily interrupt the network. If your home Wi-Fi network is spotty, the leader will have to frequently reconnect to the network, which will disrupt the followers for a brief period.
Verify the home Wi-Fi network is not on a crowded channel. Most Wi-Fi equipment will automatically change channels in response to interference, but manual adjustments may be needed. All Wall Connectors in a power sharing network will operate on the same Wi-Fi channel as the home network.
Power cycle the Wall Connectors by resetting the circuit breaker.
If a follower has been removed or replaced, remove it from the power sharing network on the leader.
In rare instances, power sharing issues could also be due to a circuit breaker trip. If this is the case, please ensure the current limit of each unit is set up properly.
