At 1800W continuous and 2700W surge, it can start a typical well or sump pump motor. Its 1024Wh battery runs a 75W CPAP with a heated humidifier for roughly 10.2 hours and a 100W mini-fridge for roughly 7.7 hours, after a 25% AC-inverter efficiency loss. At $449, that works out to $0.44 per watt-hour. It accepts up to 500W of solar input for off-grid recharging.
