Product Introduction

The ML series is a modular rack-mounted energy storage lithium battery line available in three capacities — ML5.2 (5.22kWh, 102Ah), ML10.24 (10.49kWh, 205Ah) and ML16 (16.07kWh, 314Ah) — all built on a 51.2V LiFePO4 platform. It supports multi-unit parallel connection of up to 16 units for easy capacity expansion, meeting customized energy needs for residential and commercial applications. The compact structure optimizes space utilization, and the ML16 offers 16kWh capacity — among the highest energy storage in its class. Premium LiFePO4 cells deliver 6,000+ cycles (at 25°C) for over 10 years of stable operation, with 4-level active balancing technology for precise cell-level monitoring and protection. Intelligent thermal management supports a wide operating range (-20°C~55°C discharge). Plug-and-play compatibility with inverters such as Deye, Sungrow and Growatt simplifies system integration. Backed by a 5-year warranty and UN38.3 / MSDS / CE certifications.
