BLUETTI Apex 300 Portable Power Station for Home Backup and Off-Grid Living

A built-in battery that scales with your needs:

The Apex 300 ships with a 2,764.8Wh second-generation LiFePO4 battery built directly into the unit - no external modules required to get started. Using the FlexPower Modular Energy System, capacity expands in stages all the way up to 58kWh, making the Apex 300 suitable for everything from overnight camping to multi-day home backup. BLUETTI rates the battery for more than 6,000 charge cycles while retaining 80% of original capacity, equating to an estimated 17-year service life.

3,840W output with Power Lifting Mode:

The pure sine wave inverter delivers a continuous 3,840W of AC output, which covers the majority of household appliances including refrigerators, microwaves, power tools, and medical equipment. Power Lifting Mode pushes peak output to 7,680W for high-draw tools and appliances, while the 50A bypass capability supports loads up to 12,000W - sufficient for HVAC systems and EV charging. Noise during operation sits between 40 and 50 dB.

Fast charging and solar flexibility:

AC charging brings the Apex 300 to 80% in approximately 45 minutes using TurboBoost technology. For solar, dual MPPT controllers accept up to 2,400W of panel input (2 × 1,200W, 12-60V DC, 2 × 20A). The optional SolarX 4K accessory further extends solar input capacity to 19.2kW per unit. An ultra-low AC idle consumption of around 20W means the unit draws very little when running in standby, keeping long-term running costs down.

0ms UPS switchover and app control:

The Apex 300 operates as a true uninterruptible power supply, switching from mains to battery in 0ms - fast enough that connected devices never detect the transition. The BLUETTI app connects via Wi-Fi or Bluetooth, giving full control over charging schedules, output settings, and real-time monitoring. The app also delivers Extreme Weather Alerts and supports over-the-air firmware updates.

MIL-STD-810G certified construction:

The Apex 300 carries MIL-STD-810G certification, having been rigorously tested against vibration, shock, and temperature extremes. The EnerBalance AI System manages cell health across the pack, pairing a magnetic-core transformer with a five-stage efficiency architecture to minimise energy loss. Operating discharge temperature range is -20°C to 40°C, making the unit usable in cold outdoor conditions. Regulatory certifications include CE, UL, FCC, and RCM.

Setup and Care

Getting started:

Connect the Apex 300 to mains using the supplied AC charging cable for the fastest charge.

Solar connection:

Connect compatible solar panels using MC4 connectors to the dual MPPT inputs, keeping input voltage between 12V and 60V DC and current within 20A per port. Position panels to maximise direct sunlight for the most efficient charge rate.

Long-term storage:

Store the unit at a charge level between 30% and 80% in a dry location within the -20°C to 40°C temperature range. Charge and discharge the battery fully every three to six months if the unit is not in regular use, to maintain cell health.

General care:

Keep ventilation grilles clear during operation to allow adequate airflow. Wipe the exterior with a dry or lightly damp cloth - avoid liquid ingress around ports and connectors. Firmware updates are delivered over-the-air via the BLUETTI app, so keeping the app connected ensures the unit always runs the latest software.
