FAQ
Add up the watts of the appliances you want to run during an outage and multiply by the hours. A typical home running fans, lights, a fridge and a TV for 5 hours needs about 5 to 10 kWh. Our team can size it for you.
They support CAN and RS485 communication used by mainstream hybrid inverters. Share your inverter model to confirm.
