Collection: ESS commerciale

Deploy large-scale battery energy storage for commercial, industrial, and utility-adjacent projects with this collection, spanning from a 20kWh–61.44kWh expandable LiFePO4 system up to the Sinexcel SES-90K, a 266kWh outdoor cabinet BESS built for full standalone deployment. Between those extremes sit the Sol-Ark 60kW three-phase hybrid inverter and its matching 60kW commercial energy storage system, giving you both the storage and the power conversion equipment needed for a complete facility-scale installation.

The Sinexcel SES-90K sits at the top of this range as an integrated outdoor solution: it includes a bidirectional PCS (power conversion system), EMS (energy management system), and dedicated HVAC cooling all in one IP-rated cabinet, with 208/400/480Vac 3-phase output and forced-air plus dedicated 5kW battery cooling to handle continuous commercial duty cycles outdoors. It's grid-tied and off-grid capable, with seamless auto-switching (or 30ms passive switching) for facilities where even brief outages are costly. The Sol-Ark and GSL systems, by contrast, are more modular — better suited to projects that want to size and scale storage alongside an existing or new commercial inverter setup. All units here use cobalt-free LiFePO4 chemistry with UL/UN/IEC/ISO certification and built-in BMS protection.
