Here's what our customers are saying

Atul | Katy, TX

"We had another freeze event and I was able to make a point to my [neighbors] that I don't have a generator. I don't have to produce heavy fumes to be able to power my house. And Sunrun basically helped me ride that storm."

Joyce | Houston, TX

"I love the fact that I'm secure in whatever happens to this weather. We can't control it, but with a backup with the Tesla battery, it is a wonderful experience."

Mckenzie | Magnolia, TX (Google Review)

"When my neighborhood’s power went out, the Tesla battery automatically kicked in. My internet didn’t even stutter! Super worth it if you have a lot of usage of if you’re thinking about getting a generator."

Home Battery FAQs

In an outage, your Powerwall(s) will automatically disconnect from the grid and restore electricity in your home in a matter of milliseconds. The duration of outage protection with Powerwall 3 depends on your starting charge level, energy usage, how many batteries you have.

We estimate that if your battery is charged to 100% and you're just running essentials (lights, Wifi, ceiling fans, fridge, garage door, charging electronics) you'll get about 12 hours of backup per Powerwall. If you're also running a heavy appliance like air conditioning or heating your backup time will decrease to about 4-5 hours per Powerwall.* Watch this video to learn more.

A Sunrun consultant can help you come up with a custom solution for your home.

For many customers, one home battery is sufficient. However, depending on your personal usage, backup desires, and utility bill savings potential, your Sunrun consultant may recommend more than one battery. Give us a call to get in touch with a Sunrun consultant today.

A certified Sunrun installer will mount your home battery on the wall, usually next to your electrical panel inside your garage or on the outside of your home.

GridReady is a Distributed Power Plant (DPP) program available exclusively to Sunrun customers on the NRG Reliant electricity plan. The purpose of this program is simple: when electricity demand is extremely high and the grid needs help, your home battery automatically shares power.

This support helps keep electricity stable for the entire community and prevents the utility from having to fire up emergency power plants. For providing this critical support, Sunrun provides participating homeowners with a reliable monthly bill credit. This means your battery works for you on a regular basis, earning you extra benefits beyond just blackout protection.

Power: Powerwall 3 can power over twice as much simultaneously as a standard LG Chem or SolarEdge battery. Note however that similar to a cellphone or laptop, battery life declines more quickly when using more energy all at once, so if you’re anticipating a longer outage, being mindful of your usage is wise.

Battery life: Another key difference between Powerwall and our LG Chem or SolarEdge offerings is the battery capacity. Powerwall offers 13.5kWh of storage capacity for extended battery life compared to 9.6kWh.

App experience: The Tesla app has a user-friendly interface available to Sunrun customers with one or more Powerwalls that lets you access additional energy insights related to your home energy production, consumption, and storage.

“Blinkless” backup: Powerwall features "blinkless" outage transition, which guarantees uninterrupted power supply during outages, eliminating any flicker or interruption in electricity. While many solar batteries transition power within seconds, "blinkless" backup power means your clocks and router won’t reset.

Stacking: Finally, you can stack multiple Powerwalls in your new Sunrun installation to increase flexibility and protection in an outage, particularly in extended outages.
