BLUETTI APEX 300 + 2 × B300K Expansion Combo

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

Secure unconditional home backup infrastructure, high-demand off-grid property power, or robust RV shore power independence with the BLUETTI APEX 300 + 2 × B300K Expansion Power System. Positioned as a premier, large-scale modular energy ecosystem, this high-performance bundle triples your out-of-the-box storage by pairing the cutting-edge APEX 300 master unit with two high-capacity B300K battery blocks. Delivering a massive 8,294.4Wh combined capacity straight from the box, this expandable platform gives you the native capability to safely run both standard 120V electronics and heavy-duty 240V household appliances simultaneously without complex rewiring or extra transformers.

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 or sudden storm blackouts strike, its near-instantaneous 0ms UPS switchover mechanism ensures sensitive network routers, desktop computers, medical CPAP equipment, and deep freezers 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, well pumps, clothes dryers) alongside low-voltage consumer electronics simultaneously.

• Massive 8.3kWh Initial Footprint: Combines the core station and two expansion batteries into an expansive 8,294.4Wh package that can grow iteratively up to an expansive 58kWh grid.

• 0ms Seamless UPS Switching: Ultra-fast transfer speed protects data integrity and critical equipment by taking over essential electrical loads instantly when grid inputs drop out.

• Advanced AI-Driven Peak Shifting: Features integrated software-level scheduling via the BLUETTI app to charge using solar or cheap off-peak grid pricing, then power your home during peak hours to maximize monthly utility savings.

• Extreme Weather Smart Prep: Connects via dual-band Bluetooth and WiFi, receiving localized meteorological disaster alerts 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 batteries to the main APEX 300 power station, insert the heavy interconnect cables firmly until they seat completely into the bays, then engage the structural mechanical slider locks on the plug body. Never attempt to connect or detach these high-current cables while either unit is active.

• Solar Open-Circuit Voltage Bounds: The dual solar charging inputs utilize native DC 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. (Note: Higher solar arrays require external accessories like the SolarX 4K).

• 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.
