The 120 kW automatic switching cabinet integrates STS-based control, protection, and monitoring functions to enable safe and automatic grid-connected and off-grid operation. It works with energy storage cabinets and PV inverters to support stable power distribution and coordinated energy management. The ESS-GRID Cabinet series are outdoor battery cabinets for small-scale commercial and industrial energy storage, with four diferent capacity options based on diferent cell compositions, 200kWh, 215kWh, 225kWh, 241kWh, etc. The local control screen can perform a variety of Space-saving: using door-mounted embedded integrated air. o form a set of AC micro-grid system. At the same time, it has perfect protection functions, such as over temperature, AC over and under-voltage,AC reverse sequence, emergency shutdown, fan failure, output overload, etc., to. An off-grid solar system provides complete electrical independence from the utility grid.
