  • Information

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
