⁠Commercial & Industrial ESS | Outdoor Cabinet Energy Storage System

The Outdoor Cabinet Energy Storage System


The Outdoor Cabinet Energy Storage System by GSO is a compact, intelligent, and flexible ESS solution tailored for small commercial and industrial (C&I) applications. Designed for outdoor installation, it integrates all essential subsystems including battery packs, PCS (power conversion system),EMS (energy management system), fire suppression, and thermal management  in one reliable cabinet.
With a configurable capacity range of 100 kWh to 200 kWh, this system ensures efficient energy utilization, peak shaving, backup power, and renewable integration for small-scale facilities.
