500kW DG-LC12/3 power module + filter


Reliable grid connection of DC sources




Flow battery

Fuel cell

Wide DC voltage range

EPC's 'DG' type liquid-cooled modules accept a wide range DC input from a battery or other DC source, and produce clean AC power to power nearly any load, building, or remote facility.

All the power and the intelligence resides within a single module. All thats missing is your application.


Designed for OEMs and System Integrators

The DG module is designed to enable you to deploy high-performance energy storage or other grid-connected systems.  Integrating generation, battery energy storage, and other sources has never been easier.

With automatic grid synchronization, the LC line of modules only require commands from your system controller.  They are designed from the ground-up to be both reliable as well as easily integrated into your larger system.  



Designed with reliability and robustness in mind, the LC module is a study in simplicity; it has no moving components - even the fan has been eliminated.

With available power ratings up to 500kW per module, DG modules pack the ability and the size to take your system to the next level.


Creating a robust system has never been easier.
