With Sunnova +SunSafe®, you can add a Tesla Powerwall or Enphase Encharge to your existing home solar system with little to no upfront costs.
The amount of power available from the battery during a power outage is limited, depending on the loads connected, customer usage and battery configuration (i.e., batteries in certain areas may be set up to provide you with the best economic benefit, which may affect the amount of back-up power available). Solar systems and/or batteries may require repairs after weather events and such repairs may be delayed due to forces outside of our control. No assurances can be given that the solar system or the battery will always work. You should never rely upon either of these to power life support or other medical devices.
