What's good
- 4,000 W continuous and 8,000 W surge, enough for well pumps and most central loads on a backup circuit.
- 2,600 W of solar input refills it in a few hours of strong sun.
- 30 A RV outlet plugs straight into a camper.
- IP65 dust and water rating, rare for a power station.
What to know
- 113.5 lb. Plan where it lives before you buy.
- Launched at $3,699, several times the price of a 1 kWh station.
