At 1000W continuous and 1500W surge, it cannot reliably start a typical well or sump pump motor. Its 768Wh battery runs a 75W CPAP with a heated humidifier for roughly 7.7 hours and a 100W mini-fridge for roughly 5.8 hours, after a 25% AC-inverter efficiency loss. At $499, that works out to $0.65 per watt-hour. Its maximum solar input is not confirmed in this project's research.
Pros & Cons
- Confirmed pure sine wave inverter — safe for CPAP and other sensitive electronics
- 5-year warranty — above average for this category
- Solar input spec not confirmed
Who Should Avoid This
