BLUETTI APEX 300 + B300K Expansion Combo

Whole-Home & RV Modular Battery Eco-System, 3,840W Split-Phase 120V/240V Inverter Station, Long-Life Military-Grade Tested LiFePO4 Off-Grid Generator Kit

Secure unconditional home backup security, flexible RV shore power infrastructure, or remote off-grid energy freedom with the BLUETTI APEX 300 + B300K Expansion Power System. Positioned as a premier, next-generation modular energy ecosystem, this high-performance bundle pairs the cutting-edge APEX 300 master unit with the high-capacity B300K battery block. Delivering a massive 5,529.6Wh combined capacity straight out of the box, this plug-and-play platform gives you the unique ability to safely run both standard 120V microelectronics and heavy-duty 240V appliances simultaneously without complex rewiring or compromise.

The core inverter architecture leverages an integrated, continuous 3,840W pure sine wave transformer (with a staggering 7,680W short-term surge headroom). Utilizing advanced EV-grade Lithium Iron Phosphate (LiFePO4) chemistry managed by an intelligent EnerBalance AI system, the platform is certified for over 6,000 charge cycles—promising up to 17 years of reliable daily deployment. When grid anomalies strike, its near-instantaneous 0ms UPS switchover mechanism ensures sensitive network routers, desktop computers, medical CPAP equipment, and refrigerators remain powered seamlessly without a single flicker.

Key Product Features & Core Engineering

• Dual 120V & 240V Output Capability: Native split-phase power distribution drives heavy-load household systems (HVAC elements, pumps, ovens) alongside low-voltage consumer electronics simultaneously.

• Massive Scalable Energy Footprint: Combines the core station and expansion battery into a 5.53kWh package that can grow iteratively up to an expansive 58kWh grid.

• 0ms Seamless UPS Switching: Ultra-fast transfer speed protects data integrity and sensitive electronics by taking over critical electrical loads instantly when grid inputs fail.

• Advanced AI-Driven Peak Shifting: Features integrated software-level scheduling to charge via low-rate off-peak utility pricing or solar grids, then automatically discharge during peak hours to maximize monthly energy savings.

• Extreme Weather Smart Prep: Connects via Bluetooth and WiFi to the BLUETTI app, receiving dynamic local weather warnings to automatically top off internal battery reserves before severe storms arrive.

• Rugged Military-Grade Build: Fully certified and structural stress-tested to strict MIL-STD-810G standards, incorporating detachable dust filters and a space-saving stackable locking design.

Critical Field Installation & Operational Guidelines

• Secure Interconnect Locking Routine: When linking the B300K expansion battery to the main APEX 300 power station, insert the heavy P090D cable firmly until it seats completely, then engage the structural mechanical slider locks on the plug body. Never attempt to connect or detach this high-current cable while either unit is active.

• Solar Open-Circuit Voltage Bounds: The dual solar charging inputs utilize XT60 connections accepting 12V to 60V DC up to 20A per port. Ensure that your configured solar arrays do not exceed the 60V max limit under cold morning conditions, as excessive open-circuit voltage (VOC) will instantly trip safety mechanisms.

• Sub-Zero Thermal Safety Rule: While LiFePO4 cells feature superior safety characteristics and the B300K includes structural internal insulation, avoid forcing high-rate charges when internal temperatures fall below 32°F (0°C). Allow the internal system components to warm up naturally inside an insulated cabin or RV compartment before initiating heavy charging currents.
