The Roller-16K is a high-capacity 51.2V 314Ah 16kWh LiFePO4 mobile energy storage battery designed for residential, off-grid, and small commercial solar applications. This all-in-one, wheeled (roller) LiFePO4 battery pack features Grade A cells in a 16S configuration, delivering 16.07kWh of reliable energy storage with exceptional safety, long cycle life, and easy mobility.
With IP65 protection, natural cooling, and built-in advanced BMS, it's perfect for home solar backup, peak shaving, emergency power, RV/camping use, and seamless integration with hybrid inverters (compatible via RS485 + CAN communication). The mobile design with integrated rollers and handles makes installation and relocation effortless—no heavy lifting required.
51.2V nominal, 314Ah rated capacity → 16.07kWh energy. Supports max 150A charge / 200A discharge currents for powerful output (up to ~10kW continuous).
Uses safe, stable LiFePO4 chemistry with no risk of thermal runaway. Built-in smart BMS provides full protection and supports CAN/RS485 for inverter communication.
≥5000 cycles at 90% DoD (0.5C at 25°C), offering 10+ years of reliable service — far superior to lead-acid batteries.
Roller wheels + handles for easy movement (floor-standing/mobile). Compact dimensions (881×480×251 mm) and 112.6 kg weight. 2 internal modules for serviceability.
Charge: 0°C to 55°C; Discharge: -20°C to 55°C. IP65 dust/waterproof rating, ≤3000m altitude, natural cooling (fanless, silent operation).
Supports parallel connection (multiple units for larger capacity). Wide operating voltage (40-58.4V) and high humidity tolerance (5-95% RH).
