Today, BESS solutions are cumbersome, involve additional equipment, are volatile and cost can easily triple at installation due to poor system design.

20 GB Series

Gridbox 20GB Battery Energy Storage System (BESS) is a high-energy-density product specifically designed for Utility, Commercial & Industrial applications. The 20GB BESS Solution includes our LFP Prismatic Module Strings, bi-directional inverter, isolation transformer, fire detection/suppression system, thermal management system, overcurrent protection, and our Gridbox Control System. The purpose-built enclosure's environmental control system increases service life of the battery system. Intelligent battery management technology is leveraged to improve the safety of the system and its lifespan.
