FAQ

What is the cycle life of the 112kWh battery pack in the integrated cabinet?

The 112kWh LiFePO₄ battery pack in the integrated cabinet supports more than 6,000 charge-discharge cycles at 80% Depth of Discharge (DOD). After 6,000 cycles, the capacity retention rate is still above 80%, which can meet the long-term operation needs of commercial and industrial projects (usually 8-12 years). Compared with traditional lead-acid batteries, it has longer service life and lower long-term operation costs, which is more suitable for large-scale, long-cycle energy storage projects.

What protection functions does the integrated cabinet's BMS and overall safety system provide?

The integrated cabinet is equipped with a high-performance integrated BMS and a multi-level safety protection system. The BMS provides real-time monitoring and protection for the battery pack, including overcharge, over-discharge, over-current, short-circuit, over-temperature, under-temperature, and cell balancing protection. The overall cabinet is also equipped with: fire suppression system (automatic spray when fire is detected), smoke and temperature sensors (real-time monitoring of cabinet internal environment), leakage protection, and surge protection. It can automatically cut off the circuit in case of abnormalities to ensure the safety of equipment, personnel, and the site.

Can multiple 50kW + 112kWh integrated cabinets be connected in parallel to expand capacity and power?

Yes, multiple identical 50kW + 112kWh integrated cabinets can be connected in parallel to flexibly expand total power and energy. For example, 2 cabinets in parallel can reach 100kW + 224kWh, 5 cabinets in parallel can reach 250kW + 560kWh, which is suitable for large-scale commercial and industrial projects with higher power and energy demand (such as large factories, industrial parks). The parallel connection is simple and standardized, and the system can automatically realize power and energy distribution without additional complex configuration, but it needs to be operated by professional technicians in accordance with the manufacturer's guidelines.
