Powerwall energy storage features

What is a Powerwall system?

The system learns and adapts to your energy use over time and receives over-the-air updates to add new features and enhance existing ones. Powerwall is a rechargeable home battery system that can be installed with solar. Powerwall 3 and Powerwall+ are designed for owners installing a new solar and storage system.

Why should you use Powerwall?

When your solar system generates more energy than you need, you can store the extra energy with Powerwall and save it for later. Powerwall can also recharge from the grid when utility prices are low. Your stored energy is available whenever you need it—during the day, at night or when an outage occurs.

Does Powerwall work if a power outage occurs?

When an outage occurs, Powerwall will help keep your solar system running or, if using grid power, will transition your home to stored energy instantly. With a fully integrated solar inverter, Powerwall can efficiently store solar energy and convert it into electricity to power your home.

What is the difference between Powerwall 3 & Powerwall+?

Powerwall is a rechargeable home battery system that can be installed with solar. Powerwall 3 and Powerwall+ are designed for owners installing a new solar and storage system. Solar systems are integrated directly into the Powerwall, for higher efficiency and more compact installation with solar inverters being included.

How many kWh does a Powerwall 3 store?

However, the Powerwall 3 still stores 13.5 kWh, which isn’t a change from the 2 and while good, is pretty standard for most home batteries. One of the biggest upgrades you’ll find with the Powerwall 3 is the switch to Lithium iron phosphate (LFP) battery cells from nickel manganese cobalt (NMC) cells (which is what the Powerwall 2 uses).

What is the difference between Powerwall 2 & Powerwall plus?

The Powerwall 2 and Powerwall Plus batteries are similar to one another -- the difference is how they interact with your home's energy system. The Powerwall is compatible with new and existing solar panel systems. It can also work as a standalone home battery without solar panels.
