MPS-125 Energy Storage Inverter
The world’s most capable 
microgrid inverter
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, the MPS-125 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.
This parallelable 125kW energy storage 
inverter is transformer-less, air-cooled, 
and compact, and optimized for behind-
the-meter energy storage applications.
