MPS-125 Energy Storage Inverter

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.

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.

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.
