The amount of energy storage you need depends on your typical home energy use and your current setup of GM Energy products. Every home and solution is unique. When paired with a GM Energy Home Hub & Inverter, the GM Energy PowerBank can provide the following estimated backup times running an average home*, depending on the configuration you choose:

Estimated backup Duration

• GM Energy PowerBank 10.6kWh – up to 6 hours
• GM Energy PowerBank 17.7kWh – up to 10 hours
• GM Energy PowerBank 35.4kWh – up to 20 hours

Please Note:

Only one GM Energy Home Hub & Inverter can be installed per home location and supports up to 35.4kWh of GM Energy PowerBank storage.

• If you’ve already purchased a 10kWh GM Energy PowerBank, your system can only integrate with an additional 10.6kWh GM Energy PowerBank.
• If you’ve already purchased a 17.7kWh GM Energy PowerBank, your system can only integrate with an additional 17.7kWh GM Energy PowerBank.
• If you’ve already purchased a 35.4kWh GM Energy PowerBank, your system cannot support additional energy storage.

GM Energy products must be installed by a licensed electrician or licensed contractor in accordance with all applicable national, state, and local electrical codes and standards. Customers are responsible for engaging a qualified, licensed professional. GM is not responsible for work performed by third-party electricians or contractors.

Vehicle-to-home (V2H) or bidirectional charging enables energy to flow in two directions. Not only does it send energy from your home to your EV for charging (unidirectional)—it also enables you to send energy from your V2H-capable GM EV* back to your home when the grid is down (bidirectional), providing you with a brilliant new source of backup power. 

By having your GM Energy products professionally installed by one of our preferred installation providers, you can rest assured that the equipment is installed properly, professionally and with the right permits. The preferred installer will help ensure your system is operating as intended to power your V2H-capable GM EV.* 

After installation and commissioning, your system should appear in your vehicle mobile app. If your system is not showing in the app after 24 hours, you can manually add it by tapping your profile avatar->add product->GM Energy.
