C-BESS MG 500 kW

This 3-phase energy storage systems (BESS), is a plug & play Energy Storage System combines the components necessary to provide Off-grid, Microgrid backup as well as On-grid services. The ESS is pre-engineered, assembled, wired and tested in the factory before shipping.

Integrates Onsite Assets

The Battery Energy Storage System
integrates, communicates with, and
controls assets such as on-site PV
inverters, diesel, propane, and natural
gas generators, as well as grid power.
The system is Microgrid ready with black
start capability and ships with an external
grid disconnect contactor sized to meet
a site’s backup needs.

Safety & Compliance

The ESS incorporates the highest safety and
compliance standards including UL 9540 for full-system safety, UL 9540A for battery safety, as well as inverter UL and IEEE certifications. The fire protection system incorporates multiple levels of safety.

The Current ESS Advantage

Our team will proactively work with your engineers and electricians to support early design development, system installation, on-site commissioning, and testing. We develop low voltage and communication drawings for each site. We will also work with your team to develop a site-specific line drawing.
