BLUETTI APEX 300 Versatile Power Station | 3,840W 2,764.8Wh

Serious Power for Home, Travel and Off-Grid Use

The BLUETTI APEX 300 combines a high-output 3,840W inverter with 2,764.8Wh of LiFePO4 battery capacity. It is built for customers who need more than a basic portable power station, whether that means keeping household essentials running during an outage, powering an off-grid setup, supporting a caravan or RV, or running equipment away from mains power.

Use it as a capable standalone power station or expand the system as your power needs grow. A complete APEX 300 system can scale from 2,764.8Wh to 58kWh of total capacity and from 3,840W to 11.52kW of output by combining two or three APEX 300 units with compatible expansion batteries and system accessories.

The 58kWh maximum requires a multi-unit configuration with compatible expansion batteries, hubs and accessories. The 17-year figure is BLUETTI's estimated service life, not the product warranty. Charging times and output performance depend on temperature, battery state, connected equipment and charging conditions. Optional expansion batteries, solar controllers, hubs and other accessories are sold separately unless specifically included in the selected package.
