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

The BLUETTI Apex 300 is a freestanding home battery backup system that delivers whole-home style power without requiring a rooftop solar installation. It provides true 120V/240V split-phase output, so it can run both standard 120V circuits and 240V appliances, and starts at 2,764.8Wh of EV-grade LiFePO4 capacity that's expandable up to 58kWh with B300K and B500K expansion batteries.

A 0ms UPS switchover keeps sensitive electronics running uninterrupted during a grid outage, and 12kW of bypass power lets it carry heavy loads like HVAC systems and EV chargers. The BLUETTI app adds storm-tracking alerts that automatically prep the system ahead of severe weather, plus remote monitoring and OTA updates.
