All-in-one Mini Grid energy storage system

1. Product description

Integrated and modular design, integrated with PCS 33KW converter, AC power distribution unit, E7 monitoring screen, LH75 energy storage battery module and BCU module to form a high-voltage integrated power supply system, for convenient installation and maintenance 

• For backup power, mini-grid, and ESS application, with flexible configuration and seamless transfer

• PCS: 33kW converter, a power conversion system, supports parallel operation up to 330KW (10 units in parallel); built-in BMS, supports battery heterogeneity; each 33KW converter can manage battery packs independently; supports 100% unbalanced load 

• LH75 high-voltage lithium batterries: 48V 3.6kWh single module, supports 12-15 modules in series, a single WellPack C&I Q can be exapanded to 54kWh; Each Qoma supports 4 clusters of high-voltage lithium battery packs, so 10 WellPack C&I Q can support expansion up to 54kWhx40=2160kWh 

• 24/7 local monitoring and control on E7 LCD Monitoring • System remote monitoring on NOVA App & Web 

• All-in-one design for small footprint; factory assembled and tested system enables you to get free from complicated groundwork
