Get the upper hand on electric grid outages with Sunnova SunSafe™! Thanks to its intelligent control system, SunSafe™ protects your home by managing how the energy you generate from the sun flows to your home, your battery or back to the electric grid.

Sunnova SunSafe™ is Protection Against Power Outages


These are estimated duration times for single load usage.

Thanks to its intelligent control system, Sunnova SunSafe™ will continue producing and storing energy when the electric grid is down, unlike solar-only systems. This gives you the peace of mind that as long as your solar system is operating, you can keep your home’s power up, even during natural disasters like hurricanes, floods and tornadoes.

In case of a utility power outage, your most important appliances will be powered for up to 10 hours, depending on your energy usage. This means you can keep the lights on, your refrigerator cold, use the internet or charge your phone.

Sunnova protects your solar + battery storage system for 25 years with our best-in-class comprehensive warranty. From repairs to maintenance, Sunnova Warranty has you covered. Plus, we guarantee that the system will produce the amount of energy we say it will, in your agreement, for 25 years or we’ll credit you the difference.



Sunnova SunSafe™ Energy Flow


How it Works

1. Your solar system produces energy

2. Excess energy is used to charge the battery.

3. Any additional excess energy will be sent to the grid once your battery is fully charged. Please check with your local utility to see if it offers net metering.

4. In case of a grid power outage, your home’s critical loads will be powered by the solar energy stored in your battery.

* For lease plans, monthly payments will be fixed for a 12-month period. An escalator will be applied annually, so the monthly payment will increase at the beginning of each 12-month period, starting in year 2 of the service agreement. Your solar system production will vary based on weather and other factors and your solar system’s cumulative production will be evaluated to validate annual production guarantee. Utility rates and utility rate structures are subject to change and cannot be accurately predicted. Your electricity usage may also vary from month to month. Projected savings from your solar + battery storage system are therefore subject to change. Sunnova makes no guarantees regarding credit for net energy exported to the electric grid. The amount of power available during a power outage is limited, depending on the loads connected to the secured panel and the customer usage during a power outage. Refer to the Limited Warranty in your agreement for complete warranty terms and limitations. Refer to your agreement for details, restrictions and limitations regarding to all the above.
