Energy Storage Solutions

Facing high energy prices and growing demand for energy independence, an Estonian factory adopted five MECC ECO-E233LS cabinets with an STS1000 smart ransfer cabinet and three Autarco PV inverters. The on-grid self consumption system allows daytime solar charging and night time use, maximizing renewable utilization and reducing grid reliance.

With A -powered EMS and modular all-in-one design, helps industrial clients achieve stable power supply, lower electricity costs, and smarter energy management.

FAQ

What is the cycle life of the 261kWh battery pack in the cabinet?

The 261kWh LiFePO₄ battery pack in the 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). The battery pack is specially optimized for the liquid-cooling system, with better cycle stability than ordinary energy storage batteries, and lower long-term operation and replacement costs.

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

The cabinet is equipped with a high-performance integrated BMS and a multi-level safety protection system. The BMS provides real-time monitoring and full-range 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: automatic fire suppression system (dry powder or gas spray when fire is detected), smoke and temperature sensors (24-hour 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 125kW + 261kWh liquid-cooled cabinets be connected in parallel to expand capacity and power?

Yes, multiple identical 125kW + 261kWh liquid-cooled cabinets can be connected in parallel to flexibly expand total power and energy, adapting to large-scale energy storage projects. For example, 2 cabinets in parallel can reach 250kW + 522kWh, 4 cabinets in parallel can reach 500kW + 1044kWh, which is suitable for large industrial parks, factories, and commercial complexes with high power demand. The parallel connection is standardized and modular, and the system can automatically realize power and energy distribution, with simple on-site connection and no additional complex configuration, but it needs to be operated by professional technicians in accordance with the manufacturer's guidelines.
