Overview

Power more of what matters with the BLUETTI Apex 300 Versatile Power Station, a high-output energy platform designed for home backup, off-grid power, RV use, workshops, outdoor living, and other applications where conventional portable power stations can quickly reach their limits.

With 3,840W of rated AC output and 2,764.8Wh of battery capacity, the Apex 300 provides substantial power in its base configuration while giving customers a platform designed around more demanding electrical loads.

Its defining advantage is a dual-inverter architecture capable of supplying 120V and 240V power simultaneously.

That means the Apex 300 can support a compatible 240V load while continuing to provide power to 120V equipment. The system can also accept charging from a conventional 120V source while simultaneously supporting appropriate 120V and 240V loads.

For customers building a larger energy system, the Apex 300 also offers high-power solar integration through the compatible SolarX 4K solar charge controller, creating a path from portable power toward a more substantial home or off-grid energy setup.

Why This Product Stands Out

Many portable power stations are fundamentally large 120V battery packs.

The Apex 300 is designed to go further.

Its dual-inverter architecture gives it one of the most important capabilities for customers with more demanding electrical requirements:

120V + 240V AT THE SAME TIME

That distinction matters.

A typical home or serious off-grid setup can contain very different types of electrical loads.

Some equipment operates at:

120V

while other equipment may require:

240V

The Apex 300 is designed so customers don't necessarily have to choose one voltage mode at the expense of the other.

The system can power a compatible 240V appliance while simultaneously supporting 120V equipment and accepting an appropriate 120V charging source.

That makes the Apex 300 more than a large battery for phones, laptops, and camping accessories.

It's designed as a:

SCALABLE POWER PLATFORM

for customers with broader energy requirements.

3,840W Rated Output

The Apex 300 provides:

3,840 WATTS

of rated AC output.

That gives it the ability to support substantially more demanding loads than a small recreational power station.

Potential applications can include compatible:

Refrigeration • Power Tools • Kitchen Equipment • RV Loads • Electronics • Lighting • Communications Equipment • Home Essentials

subject to each device's actual voltage, running wattage, startup demand, outlet requirements, and the Apex 300's operating limits.

Important

A 3,840W total output rating does not mean every appliance up to 3,840W will automatically be compatible.

Always account for:

• Operating wattage
• Startup/surge demand
• Voltage
• Frequency
• Outlet type
• Circuit limitations
• Simultaneous loads
• Manufacturer requirements

Verify the exact appliance before relying on the Apex 300 as its power source.

2,764.8Wh Battery Capacity

The base Apex 300 provides:

2,764.8Wh

of stored battery capacity.

That's approximately:

2.76kWh

of nominal energy storage.

This distinction between watts and watt-hours is important for customers.

3,840W

describes how much rated AC power the system can deliver.

2,764.8Wh

describes the base battery's stored energy capacity.

How long a particular appliance can operate depends on its actual consumption as well as conversion losses, temperature, battery state, operating conditions, and other system factors.

For that reason, runtime should be calculated for the customer's actual equipment rather than promising universal operating times.

Simultaneous 120V + 240V Power

This is the Apex 300's headline capability.

The system is designed for:

120V AND 240V OUTPUT SIMULTANEOUSLY

rather than requiring the owner to select only one voltage class.

This can be particularly valuable for:

• Home backup systems
• Workshops
• RV and mobile applications
• Off-grid properties
• Equipment requiring 240V
• Mixed-voltage electrical setups

Customers can operate an appropriate 240V appliance while continuing to power compatible 120V devices.

Charge While Powering Your Equipment

Highlights include the ability to:

RECHARGE WHILE SUPPLYING POWER

For example, a scenario where the Apex 300 is:

Powering a 240V Appliance

while simultaneously:

Charging from a Conventional 120V Outlet

and:

Powering Other 120V Equipment

This can provide considerably more flexibility than a system that requires customers to stop powering loads whenever the battery needs to recharge.

Actual simultaneous input/output limits should always follow current operating specifications.

Multiple Recharge Options

The Apex 300 is designed around flexible energy replenishment rather than relying on a single charging method.

This becomes especially valuable for customers using the system for:

Home Backup • Extended Outages • RV Travel • Remote Properties • Off-Grid Applications

where the best available charging source can change from one situation to another.

High-Power Solar Charging

For customers who want to build a larger solar-powered energy system, the Apex 300 can be paired with BLUETTI's:

SolarX 4K Solar Charge Controller

The SolarX 4K is a:

4,000W SOLAR CHARGE CONTROLLER

This dramatically expands the solar possibilities beyond those of a conventional portable solar-generator setup.

The SolarX 4K can be used with solar arrays ranging from approximately:

4kW–30kW

depending on system configuration.

Important

A 4,000W solar charge controller does not mean that a single Apex 300 necessarily accepts 30,000W directly into its battery.

The larger solar-array figures relate to the architecture and compatible SolarX/system configuration.

Customers should follow exact solar-input, controller, voltage, current, wiring, and system-design requirements.

Rooftop Solar Integration

The compatible SolarX 4K system can integrate with existing rooftop solar installations through:

AC COUPLING

This is potentially one of the Apex 300 ecosystem's most important features for homeowners who already have solar.

Rather than treating portable batteries and rooftop solar as completely separate systems, an appropriately configured Apex 300 ecosystem may provide a path toward greater integration.

Important Installation Note

Rooftop solar, AC coupling, transfer equipment, home electrical panels, and high-power energy-storage installations should be configured according to:

• Manufacturer requirements
• Solar inverter compatibility
• Applicable electrical codes
• Permitting requirements
• Utility requirements where applicable
• Appropriate installation practices

Do not assume every existing solar installation can be connected without additional compatible equipment.

Home Backup Applications

The Apex 300's combination of:

3,840W Output + 2,764.8Wh Capacity + 120V/240V Capability

makes home backup one of its strongest use cases.

An appropriately configured system may be used to support selected essential loads during a power interruption.

Potential examples include compatible:

• Refrigerators and freezers
• Lighting
• Internet and communications equipment
• Electronics
• Selected kitchen appliances
• Home-office equipment
• Appropriate pumps
• Other essential circuits or appliances

Exact capability depends entirely on the load and system configuration.

Important

Never connect a portable power station directly to home wiring through an improvised cord or unapproved backfeeding method.

Home electrical integration requires appropriate transfer/interconnection equipment and installation according to applicable requirements.

Off-Grid & Remote Power

The Apex 300 also makes sense outside the home.

Its high output and solar-integration potential can support energy systems for:

Cabins • RVs • Overlanding • Remote Work • Workshops • Outdoor Events • Off-Grid Properties

The ability to support both 120V and 240V loads can be particularly valuable for customers whose equipment needs extend beyond ordinary electronics and low-power camping appliances.
