Reliable and Scalable

Factory prepackaged and tested

  • Pre-engineered containershipped as a single unit with batteries, inverter, isolation transformer and other equipment installed.
  • Parallel ready - multiple modules may be used in parallel to increase total output up to 100+MW.

Renewable Integration

  • Designed to work with an array of renewable systems, including solar and wind
  • Seamless integration with Cat Microgrid Master Controller (MMC) allows for maximum renewable penetration and full asset control

Transient Assist

When used with a generator set, the Cat PGS module will provide reserve power capacity to:

  • Decrease the transient voltage and frequency dips resulting from the application of large loads.
  • Enables highly-efficient lean-burn gas gensets to operate in island mode.

Grid Stabilization

  • Protects against many typical power problems, including power failure, voltage sags/surges, and under/over frequency conditions.

High Performance Inverter

  • Built-in controls for the charging and discharging of the energy storage equipment.
  • Static VAR compensator.
  • Four-quadrant output power factor control.
  • Automatic anti-islanding to meet UL 1741 and synchronization back to grid.
