MG Series 500 kW

The MG 500KW is housed in a single 13 foot custom NEMA 3R enclosure. This enclosure can house up to 990 kWh of battery energy storage. This enclosure contains up to date fire suppression technologies. 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-500

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 BESS incorporates the highest safety and compliance standards including:

UL 9540

UL 9540A

IEEE 1547

UL 3141 (Pending)
