We love the elegant AC coupled setup here, which allows the homeowner not only 4-5 days of power autonomy during an outage, but also effectively “shed” excess power generated during a power outage through a garage-based heater. Seemlessly activates within 16 milliseconds of a blackout and sustains all critical home loads.
