AlphaESS STORION-H50-G3 C&I Storage System, 50 kW, 120.5 kWh

The STORION-H50-G3 puts everything a commercial storage system needs into one cabinet: battery modules, a 50 kW hybrid PCS with DC/DC, a static transfer switch and the energy management system. Solar connects straight to its four MPP trackers, so a new PV array needs no separate inverter. The EMS runs peak shaving, load shifting and time-of-use tariffs, and if the grid fails the site switches to battery power in 20 ms or less. Cooling is by HVAC, the enclosure is IP55 and C4 corrosion protected, and fire protection uses aerosol with smoke and temperature detection.
