Dynamic Power Management

Dynamic Power Management adjusts charge rate in real-time based on the available power in your electrical panel. This means your charge rate will always be the fastest possible, while ensuring that total power being drawn from your panel is within safe limits.

Note
Dynamic Power Management requires the purchase and installation of a Tesla-approved power meter, sold separately from the Wall Connector. Currently, these meters are available for purchase online or through a Tesla Certified Installer.

How It Works

Using a Tesla-approved power meter, Dynamic Power Management continuously monitors the available power in your panel and adjusts your Wall Connector charge rate based on electrical usage in your home. So when your home is using more power—for example, when you have a dryer and a water heater running—your vehicle will charge more slowly. But when your home is using less power—for example, at night—your vehicle will charge more quickly.

Why It's Useful

This feature allows you to get the maximum charge rate of your Wall Connector while avoiding electrical upgrades. This is ideal for homes or parking spaces with limited power.

Setting up Dynamic Power Management in the Tesla One app

Your Tesla Certified Installer will configure Dynamic Power Management when commissioning your Wall Connector by following the steps below:

  1. Install the Wall Connector and run a minimum #22 gauge shielded twisted pair communication wire from the electrical panel to your Wall Connector. In some cases, you can install this communication wire in the same conduit as the wires powering your Wall Connector.
  2. Install the power meter and Current Transformers (CTS) inside of your electrical panel.
  3. Open the Tesla One app and connect your device to the Wall Connector.
  4. Select the ‘Meter’ card in the commissioning main screen.

  5. While on the Meter screen, select the card on top to configure the meter.

  6. Set Current Transformer 1 and Current Transformer 2 as ‘Conductor.’

  7. Back on the main Meter page, set the max conductor limit.

    Note
    This value should be 80% of the panel supply conductors or main disconnector rating (whichever is lower). For example, a 100 amp main disconnect = 80 amp max conductor limit.
