🔋 20kWh High-Capacity LiFePO4 Energy Storage
Built with a 51.2V 400Ah LiFePO4 battery system, providing 20.48kWh of usable energy storage for daily home power consumption, solar energy storage and backup power applications.
⚡ Built-in 12kW/10kW Three-Phase Inverter
The integrated 12kW/10kW pure sine wave inverter delivers stable three-phase AC power, eliminating the need for a separate external inverter and simplifying system installation.
☀️ Dual MPPT Solar Charging
With dual MPPT technology, the system efficiently converts solar energy into usable electricity while supporting flexible PV system configurations for residential solar applications.
⚡⏱️Peak & Off-Peak Energy Management
Users can set charging and discharging times to match local peak and off-peak electricity tariffs. During peak hours, the inverter supplies power from the battery; off-peak, it draws cheaper grid electricity to run the load and recharge—helping you cut energy costs efficiently.
🛡️ 300A/200A Smart BMS with Active Balancing
The integrated 300A/200A BMS provides comprehensive protection against overcharge, over-discharge, overcurrent and temperature-related risks, while active balancing helps maintain battery cell consistency and performance.
🔄 All-in-One Plug & Play Design
Battery, inverter and key protection components are integrated into one compact system, reducing wiring complexity and making installation faster and easier compared with separate battery and inverter systems.
🏠 Designed for Home Energy Storage
Ideal for solar self-consumption, off-grid applications, backup power and daily household energy management. The system can store excess solar energy during the day and supply stored power when needed.
⏱️ Smart Energy Management
Supports intelligent charging and discharging strategies to optimize battery usage according to solar generation, household demand and electricity tariff periods.
📈 Scalable Energy Storage Solution
For larger energy requirements, the system can be configured with compatible units to expand total storage capacity and output power.

Precautions
•No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.
• Please check the orientation of the positive and negative terminals before packaging.
•Connect the terminal or wire to the battery module, and pay attention to insulation to prevent short circuits.
• When not in use for a long time, the battery should be stored in a cool and dry place (<35°C, 30%~50% SOC, charge and discharge once every 3 months).
• Do not place the battery in direct sunlight or a heat source.
• Do not wear metal jewelry (such as rings, watches, accessories, etc.) when handling the battery unit.
Prohibited Matters
Do not charge beyond the maximum charging rate.
Do not disassemble or modify the battery.
Do not throw or hit the battery.
Do not pierce the battery with sharp objects (such as nails, knives, pens, or electric drills).
Do not mix with other types of batteries or modular units.
Do not excessively squeeze the battery during use.
Do not place the battery in a high temperature greater than 60°C.
Do not use conductive materials to connect the positive and negative terminals (such as metals, and wires).
