2. Key Features

• Expandable Capacity: Each battery unit has a rated capacity of 6144Wh. Multiple batteries can be connected to an inverter (up to 5 batteries per inverter, or 15 batteries across 3 inverters) to achieve a total capacity ranging from 30kW to 90kW, providing extensive power backup for various needs.
• Long Lifespan LiFePO4 Battery: Utilizes LFP (Lithium Iron Phosphate) battery technology, offering over 3500 cycles before capacity degrades to 80%. This translates to approximately 10 years of regular use, ensuring long-term reliability.
• Integrated Battery Management System (BMS): Each battery houses an integrated BMS module that actively regulates voltage, current, and temperature, ensuring safe, secure, and long-lasting operation.
• High AC Output Capability: When paired with the DELTA Pro Ultra inverter, the system can deliver a single inverter output of 7200W, capable of running heavy household appliances, including a 3-ton central air conditioner. Triple inverters can achieve an incredible 21.6kW AC output.
• Dual Voltage Output (120V & 240V): Supports both 120V and 240V outputs, allowing you to power standard 120V devices while also handling high-voltage appliances like clothes dryers, heat pumps, and central air conditioning units.
• Modular and Stackable Design: The system features a modular, plug-and-play design, allowing for easy expansion and stacking of batteries to meet growing power demands.
• Versatile Charging Options: Supports multiple charging methods including gas generators (7200W input, 1.5 hr recharge), solar panels (4000W input, 2 hr recharge), EV charging piles (7200W input, 1.5 hr recharge), and standard AC outlets (3000W input, 2.5 hr recharge).
• Uninterruptible Power Supply (UPS): Provides online UPS functionality with 0-ms switchover time, offering seamless protection against power failures for critical devices.
• Quiet Operation: Operates at 0 dB under 2000W output for the first thirty minutes, ensuring a peaceful environment during use.
• Smart Power Management: Compatible with the EcoFlow Smart Home Panel 2, allowing for advanced energy management, optimization of home energy use, and reduction of electricity bills by leveraging power from the grid, solar, and batteries during peak and off-peak hours.
