51.2V 300AH Solar Lithium Battery

51.2V 300AH Solar Lithium Battery

15kWh High-Capacity Vertical Design: Compact vertical lithium battery delivering 15.36kWh total energy (51.2V × 300Ah) with 80% depth of discharge (12.29kWh usable), ideal for small-to-medium commercial spaces (cafés, retail kiosks) and residential backup. Its vertical form factor saves 40% floor space vs. horizontal units, fitting seamlessly in utility rooms, basements, or tight commercial corners.

Product Introduction
Products Description

15KWH Power Wall LiFePO4 Batteries

 

 

300Ah LiFePO4 Durability:


300Ah large-format LiFePO4 cells engineered for 6,000+ charge-discharge cycles (10+ year lifespan) at 25°C, retaining 80% capacity after a decade. Non-flammable chemistry and stable thermal performance eliminate fire risks, making it safe for indoor installations (homes, offices) where safety is critical.

 

 

51.2V Optimized Efficiency:


51.2V nominal voltage minimizes current loss in wiring, supporting 0.5C–1C charge/discharge rates (7.68kW–15.36kW). Compatible with standard 51.2V solar inverters and MPPT charge controllers, ensuring fast replenishment via solar or grid (80% charge in 4 hours) and reliable power for appliances, lighting, or small HVAC systems.

 

 

Advanced BMS for 300Ah Cell Health:


Integrated Battery Management System (BMS) with real-time monitoring of 300Ah cells-tracking voltage, temperature, and internal resistance. Balances cells to ±5mV to prevent uneven degradation, while offering overcharge/over-discharge protection, short-circuit safeguards, and thermal runaway prevention.
