Determine Your Energy Usage

How many Powerwalls should be installed in a house depends on a number of factors. Most houses only need one Powerwall, but it depends on the amount of electricity the house uses and the size of the house. You need to consider items that use a lot of power when running, such as air conditioners or heaters.

Do I Need One Powerwall Or Two?

The Powerwall's basic system consists of 10 solar panels and a Powerwall that, under ideal conditions, generates 13.5 kilowatt-hours of electricity per day and stores 12.2 kilowatt-hours in the Powerwall.

For small grid-connected homes, one Powerwall is enough to power your entire home. For off-grid homes, you may need up to two, depending on the number of people and types of appliances you use.

Powerwall vs Powerwall Plus

While the Powerwall stores solar energy from the grid and third-party solar inverters, the Powerwall plus takes storage to the next level by integrating a Tesla solar inverter and system controller. These features enable interconnection of DC-coupled solar systems.

One of the drawbacks of a DC-coupled system is that it must be paired with solar equipment made by the same manufacturer - in short, the Powerwall Plus must be paired with a Tesla MCI using a Tesla inverter.

Choose Powerwall or Powerwall Plus?

If you want to install a solar system at the same time as the Powerwall, you can choose the Powerwall Plus, which will save you some money on the cost of the inverter. If you're adding to an existing solar system, you can choose the Powerwall, which is compatible with third-party inverters.
