Bluetti Apex 300 Portable Power Station and Accessories
The Bluetti Apex 300 is one of the most versatile portable power stations available today. It sits in a category of its own: serious enough to handle home backup, flexible enough for RV and off grid use, and compact enough to move around when you need to. With 2,764.8Wh of built-in LiFePO4 capacity and 3,840W of continuous AC output, the Bluetti Apex 300 power station can run a refrigerator, an air conditioner, power tools, medical equipment, and everyday electronics simultaneously without breaking a sweat.
At Off-Grid Source, we carry the full Apex 300 ecosystem including the base unit, compatible expansion batteries, and accessories designed to extend what the system can do.
Bluetti Apex 300 Capacity and Core Specs
Understanding what the Bluetti Apex 300 is built on helps explain why it performs the way it does. Key specs worth knowing:
-
2,764.8Wh base capacity built with 2nd generation automotive grade LiFePO4 cells rated for 6,000 charge cycles to 80% capacity, translating to roughly 17 years of daily use
-
3,840W continuous AC output with 7,680W surge power to handle high startup loads from motors, compressors, and large appliances
-
Simultaneous 120V and 240V output through six AC outlets, so you can run both standard and high voltage loads at the same time without adapters or compromises
-
2,400W built-in solar input for fast recharging off panels. With the optional SolarX 4K expander, total Bluetti Apex 300 solar input scales up to 19.2kW for serious off grid setups
-
20ms UPS switchover so connected devices experience no meaningful interruption when switching from grid to battery power
-
Black start capability allowing the unit to restart from a fully depleted state using solar energy alone
Expanding the Bluetti Apex 300 System
The base Bluetti Apex 300 already covers a wide range of scenarios, but the real strength of the system is how far it scales. A few expansion paths available through our collection:
-
B300K expansion battery (3,072Wh). Connects to the Apex 300 in around 10 minutes and immediately increases total storage. Up to six B300K units can be added, bringing total system Bluetti Apex 300 capacity to over 19kWh.
-
B500K expansion battery (5,120Wh). A higher capacity alternative compatible with the Apex 300 for customers who want to maximize storage in fewer modules.
-
Hub D1 DC power hub. Clips directly onto the Apex 300 and adds 700W of organized DC output including a high current Anderson 50A port for RV fridges, diesel heaters, and rooftop AC units. Required for full AC and DC RV power integration.
-
Hub A1 parallel connection. Links two or three Apex 300 units together for up to 11,520W of combined output, suitable for larger homes and commercial mobile setups.
What the Apex 300 Is Built For
The Bluetti Apex 300 handles a wide range of real-world scenarios without needing to be reconfigured for each one.
