DG Module: Ready for Harsh Environments.

Liquid-cooled Distributed Generation Power Module

EPC’s liquid-cooled distributed generation modules offer advanced power conversion for today’s distributed generation applications.

Designed with reliability and robustness in mind, the liquid-cooled distributed generation module is a study in simplicity. 

With available power ratings of up to 500kW per module, EPC’s distributed generation modules will take your distributed generation system to the next level.

Key benefits:

  • Compatible with all battery chemistries
  • Multimode operation for grid-tie and off-grid plus parallel UPS backup
  • Storage & Microgrid PCS
  • Liquid cooled for harsh environments
  • Flicker-free resynchronization and reconnection of critical loads after grid outages
  • Real and reactive power control
  • Fully bi-directional
