Lithion Battery > 500-1000kW, 552-1104kWh, 480 VAC Commercial Battery Energy Storage System (BESS) - Business Battery Backup
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 Lithion Battery Modules, bi-directional inverter, isolation transformer, thermal management system, overcurrent protection, and our Gridbox Control System.
An environmental control system is also built in the container, which increases service life of the battery system. Intelligent battery management technology is leveraged to improve the safety of the system and its lifespan.
Why batteries for my business?
Savings and security.
Installing a power storage system with renewable generators (solar/wind) can save your business money every day and provide security against grid failure. A battery can help offset time-of-use charges and electrical multipliers from large equipment. It also provides security in case of a power outage by backing up necessary circuits or your entire business. Most businesses rely on electricity, and many would be devastated in the event of an outage. We provide solutions for hospitals, technology businesses, factories, and many more.
