The BLUETTI Apex 300 is a modular, dual-voltage power station with 2,764.8Wh of LiFePO4 capacity and 3,840W of continuous output (7,680W surge), able to run 120V and 240V devices simultaneously. It's designed to grow with expansion batteries (B300K, B500K) and accessories up to 58kWh and 11.5kW output, making it suited for whole-home backup, RV power, or off-grid living. With near-instant UPS switching (0–20ms), up to 4,000W of solar input (with SolarX 4K), and smart BLUETTI app control including storm alerts and peak-load-shifting to cut energy bills, it's built as a long-term home energy hub more than just a portable unit, but can be used wherever you want it.
