Before you hire a home battery installer

  1. Ask for the usable storage (kWh) and the continuous power (kW), and which circuits it will keep running in an outage.
  2. Ask whether the battery is on your rebate program's approved list. Brands not on the list get no rebate.
  3. Ask where it will go. Some batteries lose capacity or stop charging in a cold garage.
  4. Ask about the warranty: years, and how much capacity it keeps by the end.

Before you call anyone, check what home battery rebates you can get in Oyster Bay. Many programs require approval or a registered contractor before work starts.
