Powerful 3,840W modular power station with 2.76kWh LiFePO₄ capacity, expandable battery storage and serious home backup, RV and off-grid capability
The BLUETTI Apex 300 is a powerful modular portable power station designed for home backup, RV use and serious off-grid power. It combines a 3,840W pure sine wave inverter with a 2,764.8Wh LiFePO₄ battery and can be expanded with up to six compatible BLUETTI expansion batteries per Apex 300.
Use it as a standalone plug-and-play power station, expand it for longer runtimes, or integrate it into a much larger BLUETTI energy system as your power requirements grow.
3,840W AC Output 2,764.8Wh LiFePO₄ 7,680W Lifting Power Expandable Battery System 2,400W Solar Input 5 Year WarrantyRun demanding appliances, tools and household essentials with up to 3,840W of continuous AC output and 7,680W lifting power for compatible high-startup loads.
Start with the built-in 2.76kWh battery and add up to six compatible B300K, B300S or B300 expansion batteries to increase runtime as your needs grow.
Dual solar inputs support up to 2,400W directly into the Apex 300, making it an excellent option for off-grid cabins, RVs and remote properties.
LiFePO₄ battery chemistry provides 6,000+ cycles to 80% original capacity, backed by intelligent battery management and a 5-year warranty.
With 3,840W of continuous AC output, the Apex 300 is capable of powering a wide variety of household, mobile and off-grid equipment.
The Apex 300 can be used as a straightforward plug-and-play backup power source for essentials such as refrigeration, lighting, communications and electronics during a power outage.
For larger requirements, multiple Apex 300 units and expansion batteries can be combined into a much more substantial modular backup system.
The Apex 300 is particularly well suited to RVs, campervans, cabins and off-grid properties where high inverter output and flexible charging options are required.
Charge from AC power, solar panels, a generator or vehicle charging, then expand the battery capacity later if your energy requirements increase.
The Apex 300 has two independent solar inputs, each supporting up to 1,200W, giving a combined direct solar input of up to 2,400W.
| Solar Input | 2 × 1,200W |
|---|---|
| Solar Voltage Range | 12–60V DC per input |
| Maximum Current | 20A per input |
| Maximum Direct Solar | 2,400W |
Under suitable conditions, BLUETTI states that 2,400W of solar input can charge the Apex 300 to approximately 80% in around 55 minutes and fully recharge it in around 75 minutes.
Actual charging performance will vary depending on panel output, weather, temperature and system configuration.
For much larger solar installations, the Apex 300 can also be paired with BLUETTI’s optional SolarX 4K solar charge controller.
A single SolarX 4K can support up to 4,000W of solar input, while larger multi-unit Apex 300 systems can be configured with additional SolarX 4K controllers for substantially higher solar charging capacity.
SolarX 4K is an optional accessory and is not included with the Apex 300.
One of the biggest advantages of the Apex 300 is its modular battery architecture. Each unit can support up to six compatible expansion batteries.
| Compatible Expansion Batteries | B300K / B300S / B300 |
|---|---|
| Maximum Expansion Batteries | Up to 6 per Apex 300 |
| Multiple Apex Units | 2–3 units can be combined in larger system configurations |
| Maximum Large-System Capacity | Up to approximately 58kWh depending on configuration |
This allows you to start with the Apex 300 itself and build additional storage capacity over time rather than replacing the entire system.
Charge from a standard wall outlet at up to 2,300W, or up to 3,450W maximum AC input where the appropriate supply is available.
Connect up to 2,400W of solar directly to the Apex 300 through its dual MPPT solar inputs.
A suitable generator can be used when solar or mains electricity is unavailable, providing an excellent backup charging option for remote use.
Recharge while travelling from a 12V or 24V vehicle system, with faster vehicle charging configurations also possible using compatible BLUETTI accessories.
Monitor and manage the Apex 300 through the BLUETTI app using WiFi or Bluetooth.
The Apex 300 supports approximately 20ms switching, helping keep sensitive equipment operating when the incoming power supply is interrupted.
This makes it suitable for equipment such as communications gear, computers and CPAP machines where continuity of power is important.
