Colossal Capacity and Unwavering Power 8.29kWh & 3,840W Output

This configuration represents a paradigm shift in what a modular power station can achieve. The fusion of the Apex 300 and two B300K2 batteries creates an energy bank that stands in a league of its own.

• Unrivaled Runtime: Power an extensive suite of appliances for days on end. Sustain a standard refrigerator (150W) for over 55 hours, a medium-sized window AC unit (1,000W) for over 8 hours, or an entire RV’s worth of systems, including lighting, ventilation, refrigerator, and entertainment, for a full weekend without requiring a recharge. This capacity turns anxiety during outages into absolute confidence.
• Dominant Appliance Support: The massive 3,840W pure sine wave inverter output provides clean, stable power equivalent to multiple home circuits. Simultaneously run high-demand appliances like central air conditioning units (requires soft start), well pumps, power tools, kitchen appliances, and entertainment systems without a flicker. This Bluetti power station bundle doesn’t just run essentials; it maintains your standard of living uninterrupted.

The Ultimate Power Ecosystem Scalable to a Massive 19kWh

This triple-battery bundle is the most powerful and practical entry point into Bluetti’s expansive FlexPower ecosystem, designed for those with significant energy demands from day one.

• A Foundation of Abundance: Starting with 8.29kWh places you in the top echelon of portable energy users. This capacity is sufficient for the vast majority of whole-home backup and off-grid living scenarios, providing a tangible sense of limitless power.
• Future-Proof Expansion: Even at this scale, the system’s modularity remains. The Bluetti Apex 300 can be expanded further, supporting a total capacity of up to 19kWh for those with extreme energy requirements, such as powering large workshops or entire eco-homes. Your investment is protected and can grow exponentially if your needs ever do.

Complete Whole-Home Backup: Uninterrupted Life During Outages

When storms or blackouts strike, this bundle ensures your home doesn’t just survive, it thrives. This is the gold standard in plug-and-play home backup.

• Total Home Integration: Go far beyond keeping the lights on. With 8.29kWh, you can seamlessly power critical circuits for days. This includes multiple refrigerators and freezers, HVAC systems (depending on unit size), home internet and office setups, security systems, and medical equipment. Your family’s comfort and safety are guaranteed.
• Automatic and Seamless: Experience the convenience of a generator-style backup without the noise, fumes, or maintenance. The system’s 20ms automatic switchover is faster than the blink of an eye, ensuring sensitive devices like computers, CPAP machines, and DVRs continue operating without a single reboot or glitch.

A Power Investment That Generates Serious ROI Master Renewable Energy

This system transforms from a safeguard into a strategic financial asset by leveraging maximum solar integration.

• Maximised Solar Savings: The Apex 300’s capability to accept up to 4,000W of solar input (with the SolarX 4K regulator) means you can recharge even this vast 8.29kWh capacity efficiently using free sunlight. This allows for profound energy independence, significantly reducing or even eliminating your electricity bills by storing off-peak solar energy for use day and night.
• Energy Arbitrage: In regions with time-of-use billing, you can charge your unit with solar or during off-peak hours and use the stored energy during expensive peak-rate periods, leading to substantial savings that can accelerate the return on your investment.

Multiple Ways to Recharge Unmatched Versatility for any Scenario

Replenishing a capacity this large is effortless with the Apex 300’s industry-leading charging flexibility.

• TurboBoost AC Charging: Even with this immense capacity, the groundbreaking 2,990W+ AC charging can rapidly refill the system, getting you from zero to full power in a fraction of the time of conventional stations.
• High-Speed Solar Charging: With BLUETTI’s optional SolarX 4K system, you can create a solar array capable of delivering up to 4,000W of input, making solar the primary and most cost-effective method for recharging this entire bank, even under less-than-ideal light conditions.
• Generator & EV Charger Compatibility: For ultimate peace of mind, the system can be rapidly recharged at 2,990W Max from a backup generator or a Level 2 EV charging station, ensuring you have a reliable recharge method in any weather, 24/7.

EnerBalance AI System & Military Durability Engineered for a Decade of Service

The advanced technology within this Bluetti power station bundle ensures legendary reliability and a long service life.
