Hydra Module: Solar + Storage.

Liquid Cooled Hydra.
200 kW | Liquid Cooled | AC-DC | DC-AC

EPC’s liquid-cooled ‘Hydra’ modules give you maximum power density and durability plus easy implementation for combined solar + storage systems. With full 4-quadrant operation, Hydra Modules eliminate the need for separate solar and storage inverters, allowing direct connection of all power-producing and storage components to a single PCS, providing a clean, well-controlled grid connection.

EPC’s Hydra modules can also be configured as a microgrid with islanding, UPS, and blinkless transition capability.

With a grid connection power rating of up to 200 kW at 480 VRMS per module, EPC’s Hydra modules can be configured in parallel to match your systems’ power requirements.

Key benefits:

  • Compatible with all battery chemistries
  • Multimode operation for grid-tie and off-grid plus parallel UPS backup
  • Fully bi-directional
  • Liquid cooled for harsh environments
  • Flicker-free resynchronization and reconnection of critical loads after grid outages
  • Real and reactive power control
  • Investment Tax Credit may apply for when used for wind and solar generation
