Commercial & Industrial Energy Storage


Commercial and industrial power consumers know that energy costs can have a significant impact on your bottom line. Energy storage allows you to manage your energy costs by giving you control over when you use grid power, protecting you from demand charges and variable energy rates to deliver substantial savings. Energy storage can also provide critical backup power for commercial and industrial facilities, preventing lost revenue from production and costly equipment damage. Pairing commercial energy storage with renewable sources such as solar or wind allows you to maximize your use of these intermittent sources by storing excess energy when it is produced and using it when needed.


To date, Dynapower has supplied over 500MWs of energy storage inverters, DC converters and fully-integrated energy storage systems worldwide. Dynapower energy storage inverters power the United States’ largest wind plus storage farm in Notrees, Texas (36MWs), the US’ first utility-scale solar plus storage facility in Rutland, Vermont and the nation’s largest NetZero building in Los Angeles, California.

Batter Backup1

Backup Power

Power outages cost commercial & industrial businesses tens of billions each year in the US alone. Dynapower’s energy storage solutions utilize proprietary, patented technology to provide seamless, uninterrupted backup power during grid outages and prevent costly downtime.

Demand Response

Demand Response

By leveraging energy storage to reduce power consumption from the grid during periods of high demand, commercial and industrial facilities can participate in demand response programs and earn incentives from your power provider.

cost reduction

Demand Charge Reduction

Typically based on your peak 15 minutes of power consumption during a billing period, demand charges often represent 30-70% of a commercial electric bill. Energy storage can be used to eliminate these peaks and reduce or eliminate these costly charges.



Energy storage paired with renewable generation enables you to build a localized grid that can disconnect from the main power grid in the event of a power outage to operate independently and reinforce overall grid resilience.

Renewables Integration

Renewables Integration

Maximize use of renewable energy sources when combined with solar or wind. Combining energy storage with intermittent sources like solar and wind allows commercial customers to store this energy when it is produced and use it when it is needed.

Time Shifting

Energy Time Shifting

Energy storage allows you to shift your peak load away from the grid at high demand times – when electricity providers charge more. By shifting your grid energy use during the day, you can reduce energy charges throughout the year



The MPS®-i125 EHV is a 125kW behind the meter Energy Storage System that combines Dynapower’s highly efficient UL 1741 SA certified MPS®-125 EHV with Li-Ion batteries in a temperature controlled NEMA 3R-rated battery enclosure. The highly compact integrated system is easily deployed on a concrete pad, crushed stone or on the ground with a forklift and minimal labor, reducing system installation costs for integrators and system owners.

The 125kW Behind The Meter Energy Storage System features Dynapower’s proprietary Dynamic Transfer™ which, in the event of a grid disturbance, seamlessly switches a facility from grid-tied to battery backup power. MPS®-i125 EHV systems can be paralleled together to meet the sizing needs of any behind the meter installation. The MPS®-i125 EHV is capable of interoperation with other DER including solar, wind and diesel gen sets, and is able to operate in both grid-tied and microgrid applications.

MPS®-i125 EHV includes:

  • MPS®-125 EHV Smart Energy Storage Inverter (UL 1741 SA)
  • Outdoor Rated, Climate Controlled NEMA 3R Enclosure for Batteries
  • Batteries – Configurable for 2, 4, or 6-hour duration
  • All AC and DC Switchgear
  • Local Energy Storage Controller
  • AC Overcurrent Protection
  • Integrated DC Input Fuses
  • Redundant HVAC Cooling System
  • Direct Release Fire Suppression System 
  • DC Pre-Charge


BLACK START — In the event of a complete system power outage, Dynapower’s patented Black Start restores power to the facility without the need for external power. Dynapower’s Black Start technology can start distribution networks even with transformer magnetizing currents that exceed the power rating of the inverters. Multiple MPS®-i125 EHV units can be restarted at once.

E COMP— A Volt Var function that provides immediate and automatic voltage support to the grid.

F COMP— A Hz-Watt function that provides immediate and automatic frequency support to the grid.

DYNAMIC TRANSFER™ — Dynapower’s proprietary patented Dynamic Transfer algorithm monitors grid stability and, upon detecting a grid disturbance, disconnects from the grid and transitions to stand-alone battery backup power mode on the load connection. The transition is seamless to the critical loads and supports 100% phase imbalance in UF mode.
