20kWh Mobile LiFePO4 Energy Storage System – 51.2V 400Ah Premium Residential Power
Core Commercial Advantages:
- The 20.48kWh "Sweet Spot": Packing an impressive 20,480Wh of stored energy, this unit is perfectly sized to capture excess daytime solar generation and power a modern home through the night. It drastically reduces reliance on the grid and accelerates your return on investment (ROI).
- Heavy-Duty 200A Discharge: Unlike standard batteries, our 400Ah model supports a continuous maximum discharge current of 200A. This ensures stable, uninterrupted operation of high-surge household appliances, such as HVAC systems, well pumps, and EV chargers, without triggering system overloads
- Ultra-Long Cycle Life (6000+ Cycles): We utilize exclusively graded A-level Lithium Iron Phosphate (LiFePO4) cells. Coupled with our advanced thermal design, the system is certified to deliver over 6,000 deep charge/discharge cycles, offering a reliable lifespan that spans over a decade.
- Intelligent Monitoring & Compatibility: The integrated Smart BMS features a high-definition interactive LCD touch screen for real-time diagnostics. With built-in RS485, CAN, and RS232 protocols, it communicates seamlessly with the world's leading hybrid inverters (including Victron, Growatt, Deye, and SMA) for true plug-and-play integration.
- Industrial-Grade Mobility: Housed in a sleek, reinforced chassis (745400810mm), the 198kg unit is equipped with heavy-duty industrial casters. This allows for effortless, single-person positioning in garages or utility rooms, completely eliminating the need for expensive wall-mounting brackets.
