Easy Installation & Maintenance
Adopts standard 19-inch 3U rack-mounted modular design for quick installation. Simple and comfortable maintenance operations.
Eco-friendly
The entire module is non-toxic, pollution-free and environmentally friendly.
Intelligent BMS System
Built-in multi-protection functions against over-discharge, over-charge, over-current, high and low temperature. The system automatically manages charge and discharge status, and balances current and voltage of each cell.
Safe & Durable
Cathode material adopts LiFePO4, featuring high safety performance and long cycle life. Low self-discharge rate; can be stored for up to 6 months without on-board charging. No memory effect, excellent shallow discharge performance.
Flexible Configuration
Multiple battery modules can be connected in parallel to expand capacity and power. Supports USB upgrade, optional WiFi upgrade, and remote upgrade compatible with Deye inverters.
Wide Operating Temperature Range
Operating temperature ranges from -20°C to 55°C, delivering outstanding discharge performance and long cycle life under extreme temperatures.

A: Yes. This is an industrial-grade energy storage device involving high voltage and high current wiring. Installation, wiring and system commissioning must be completed by professional electricians or engineers. Unauthorized operation by non-professionals is strictly prohibited.
A: Multiple units can be stacked and paralleled for flexible capacity expansion according to power demand. A single system supports up to 16 parallel units (slight differences among models), covering full scenarios from small residential to large industrial & commercial energy storage.
A: The cycle life of LiFePO4 batteries is over 5 times that of lead-acid batteries. The size and weight are reduced by 50%. Maintenance-free and free of heavy metal pollution. The full-lifecycle cost is only 1/3 of lead-acid batteries, making it an ideal replacement for lead-acid batteries.
A: Discharge is supported from -10°C to +55°C. Charging below 0°C is forbidden. A heating module is required for long-term use in extremely cold environments.
