MPS-125 Energy Storage Inverter
The world’s most capable microgrid energy storage inverter
This parallelable 125kW energy storage inverter is transformer-less, air-cooled, compact, and optimized for behind the meter energy storage applications.
Featuring a highly efficient three-level topology, the MPS-125 is easily integrated into customer supplied battery storage systems or can be supplied as part of Dynapower’s fully-integrated MPS-i energy storage system. Multiple MPS-125 energy storage inverters can be paralleled together to scale to meet the needs of any behind-the-meter energy storage installation. With all the functional capabilities of the grid-scale CPS inverter family, the MPS-125 supports frequency, voltage, and VAR support applications.
With our patented Dynamic Transfer™ feature, this inverter monitors grid stability and will automatically disconnect and transition to stand-alone mode if a grid disturbance is detected, ensuring consistent power to critical loads.

Islanded Operation (UF Mode)
The MPS-125 includes the ability to run islanded mode (voltage source) operation, also called UF mode. In islanded mode, the MPS-125 accepts Voltage (U) and Frequency (F) setpoints. The MPS-125 can handle full real power transitions with extremely tight voltage and frequency regulation forming a ‘stiff backbone’ to the microgrid.
Dynapower’s 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.
In the event of a complete system power outage, our patented black start restores power to the facility without the need for external power and can start distribution networks even with transformer magnetizing currents that exceed the power rating of the inverters. Multiple MPS®-125 EHV units can be restarted at once.
Frequency Compensation Mode (F- Comp)
F-Comp monitors the grid frequency for deviations from nominal, and if a deviation exceeds a max allowed, the MPS-125 will automatically follow a user-defined frequency correction curve. F-Comp is ideally suited to very rapid Fast Frequency Regulation applications as well as power quality correction of critical facility loads.
Volt-VAR Compensation Mode (E-Comp)
E-Comp monitors the grid voltage for deviations from nominal and automatically attempts to correct three-phase voltage magnitude deviations (usually voltage sags) experienced by a critical load in an effort to avoid the need to transfer to backup power mode.
