The BLUETTI Apex 300 Portable Power Station combines a 2,764.8Wh LiFePO4 battery with a 3,840W pure sine wave inverter and both 120V and 240V output from a single unit. It runs RV appliances through a TT-30R outlet, feeds a home panel or 240V equipment through a NEMA 14-50R outlet and keeps critical loads on with 0ms UPS switchover.
The Apex 300 is built to expand. Add up to six B300K batteries per unit for up to 19,353.6Wh, or connect up to three Apex 300 units through a Hub A1 for up to 11,520W of output. Our listing offers the Apex 300 alone, with B300K or B500K expansion batteries, with two 200W portable solar panels, or as a two-unit parallel system with the Hub A1.
Four 20A AC outlets, a NEMA TT-30R RV outlet and a 120/240V NEMA 14-50R outlet share 3,840W of continuous output. Power Lifting mode supports resistive loads up to 7,680W. You can run 120V and 240V devices at the same time, even while the unit is charging.
When connected to grid power and configured properly, the Apex 300 switches to battery in as little as 0ms, so lights, network gear and CPAP machines stay on through an outage. An Extreme Weather Alert in the app can automatically switch the system to Emergency Backup mode before a storm.
Turbo AC charging pulls up to 3,840W from a standard outlet to reach 80% in about 45 minutes and full in about 65 minutes. Standard (1,440W), Silent (500W) and Custom modes are also available. You can recharge from a 120V or 240V generator, an EV charging station or an RV park pedestal at up to 3,600W.
Two XT60 solar inputs each accept up to 1,200W at 12V to 60V and 20A. Add an optional SolarX 4K controller (requires at least one B300K) for up to 4,000W more from high-voltage strings, for a combined maximum of 6,400W per unit.
Each Apex 300 supports up to six expansion batteries, and you can mix B300K, B300 and B300S models. The B300K adds 2,764.8Wh, and the larger B500K adds 5,120Wh. With a B300K connected, firmware updates both units in one step.
Connect two or three Apex 300 units to a Hub A1 with parallel cables and they enter parallel mode automatically. Three units reach 11,520W of output and up to 58,060.8Wh with 18 B300K batteries. UPS mode works across the whole parallel system.
EV-grade LiFePO4 cells with BLUETTI's EnerBalance AI system are rated for 6,000+ cycles to 80% capacity. Idle loss is about 20W, and the unit is tested to MIL-STD-810G. Time-of-use scheduling lets you charge during low rates and power your home at peak times.
USB-C, USB-A, 12V car and DC5521 outlets and a 12V/50A Anderson port are available through the optional Hub D1 power hub, which is rated at 700W. The Apex 300 itself focuses on high-power AC output.
Home backup. Connect to a transfer switch or home integration kit to keep a refrigerator, furnace fan, well pump and lights running during outages.
RV and van life. Plug the TT-30R outlet into your RV, recharge at campgrounds or from your alternator with a Charger 1, and add solar for extended stays.
Off-grid cabins. Store solar energy and run 240V tools or appliances without a separate inverter.
Jobsites. Run saws, compressors and chargers quietly with no fuel or fumes.
Versus the BLUETTI AC300 and AC500. The Apex 300 builds on those systems with a built-in 2,764.8Wh battery, a simpler setup, more app control and one-tap OTA updates.
Versus gas generators. It runs silently with no fuel, provides 0ms UPS backup and recharges from solar, while still offering 240V output.
Versus permanent home battery systems. The Apex 300 needs no fixed installation for portable use and can move between your home, RV and jobsite.
This may be a good fit if
One Apex 300 with six B300K batteries reaches 19,353.6Wh. With six B300 or B300S batteries it reaches 21,196.8Wh. Three units in parallel with 18 B300K batteries reach 58,060.8Wh.
Yes. Each array must have a total open-circuit voltage of 12V to 60V and connect to the XT60 input with an MC4-to-XT60 or similar cable. Do not mix different panel types in one array.
Yes. The Apex 300 supports black start from solar or other external power, even when fully drained.
No. Keep it dry during use.
