This item is a self-contained component and does not require professional installation on its own.
Verified pairings are listed under “Completes this system” below — they match this product's voltage class and connectors.
Never mix battery and inverter voltage classes: a low-voltage (51.2V) battery cannot be connected to a high-voltage inverter input, and vice versa. If you are unsure, talk to an engineer before ordering — the check takes minutes and prevents damaged equipment.
This product carries a 2-year manufacturer warranty.
Returns and warranty claims both start by contacting us with your order number. The full terms are on our delivery and returns page.

Common questions
How long will a power station run my appliances?
Divide the station capacity in Wh by the appliance draw in watts, then subtract inverter losses. A 1,000Wh station runs a 100W load for roughly nine hours.
Can I charge a power station with solar panels?
Yes. Match the panel voltage and current to the station input limits, and use the EcoFlow solar cable where the connector differs.
Can a power station back up my whole house?
A portable station covers essentials — lights, router, fridge and phones. Whole-home backup needs a fixed inverter and battery sized to the property.
