Like the Tesla Powerwall, Orison is a rechargeable home battery/power supply. A single Orison puts out 2.2 kWh—enough to power an AC Unit, a laptop, and a television set for six hours, plus a refrigerator for 24 hours a day. With their simple online tool you can figure out exactly how many hours it will take to power your place. Using a cloud system, the units determines the best time to recharge so they’re never drawing power at peak hours. And that saves money. Orison units are available in wall mount or tower form.
