MG Series 125 kW

The MG 125 is 3-phase, 480 VAC 125kw, commercial battery energy storage system. Expansion enclosures can be added to increase the battery storage from 110 kWh to 880 kWh. The BESS can be run in off grid systems or grid Connected where it can provide grid resiliency and grid services. The BESS is manufactured and tested in the USA.

MG-125

Integrates Onsite Assets

The BESS’s EMS manages communication to on-site PV inverter, generators, ATS, power meters and load control systems. The MG 125 is provided with an external grid disconnect contactor and programmed SEL 751 relay. The EMS is provided with a cellular modem and LAN port for internet access.

Safety and Compliance

The BESS incorporates the highest safety and compliance standards including:
