Technical Summary
Application The Cat ECS 400 is used in a variety of microgrids where the Cat ECS 400 is configurable to meet applicable site-specific asset requirements.
Module Type Monitoring / control and asset optimization may be configured with up to 32 Distributed Energy Resources (DER's).
Environmental Parameters
Enclosure Rating NEMA 1 wall mountable

Applicable Codes and Standards

  • UL 508A; Note codes may not be available in all model configurations. Please consult your local Cat dealer for availability.
  • NEMA Type 1
  • SunSpec® Compliant

Standard Components

  • Best Battery Diode (BBD) for backup power supply.
  • Managed switch that offers configurable site communication and enhanced security provision to assure network integrity. One ethernet (4-Wire) port connection for customer networking of DER's.
  • Telematics PLE702 (See LEHE22212) allows data logging of 300 channels for 1.5 days (requires subscription for visualization).

Input/Output Ethernet Modules

  • Supports expanded Inputs/Outputs (IO) capability of the Cat ECS 400 control: - Analog & digital I/O - Temperature sensing (RTD).
  • Configure I/O for any event (read & write function).
  • Interface with a single ATS and other relays that allows load shed/load add with up to eight (8) load breakers.
  • Package mounted and/or ship loose options (See LEHE22466).

Control Modes | Auto | Grid Connected - Sub-modes (16):

  • Unplanned Islanding or Emergency standby - Closed transition (with soft unload) or Open transition
  • Planned Islanding or Intentional islanding
  • Load sense/load demand - Based on asset priority or engine-hour balancing - Automatically matches on-line asset capacity to the loads
  • Load shed/load add - Automatic or manual load shed up to eight (8) stages
  • Utility parallel, import power from grid - Minimum import kW setpoint is maintained
  • Utility parallel, export power to grid -Target export setpoint is maintained
  • Utility parallel, base load operations
  • Economy mode - All Gensets and non-renewable "fuel consuming" assets OFF
  • Reliability mode - At least one high priority "fuel consuming" asset ON
  • Scheduling - 5 schedules and 6 segments - BESS dispatch scheduling based on year, month, time, day and segment of day - 5 schedules and 6 segments - Import and export scheduling for active and reactive power based on time, day and segment of day
  • Load smoothing mode - Non-stable load dispatch using available assets for specified durations of time
  • 3 Flexible efficiency modes 1, 2 and 3 that may be set up based on asset group priorities
  • Pro-active add and drop - Ability to manually bring additional gensets online in anticipation of bringing on large loads. - Manually turning off gensets instead of waiting for LSLD drop when the customer knows large loads are being taken offline
  • Grid Reactive Control mode - There are 4 available reactive power control settings - Constant VAr, Constant PF, Volt-VAr curve, Watt-VAr curve.

Control Modes | Auto | Off-Grid (Island) - Sub-modes (7):

  • Pro-active add and drop - Ability to manually bring additional gensets online in anticipation of bringing on large loads - Manually turning off gensets instead of waiting for LSLD drop when the customer knows large loads are being taken offline

Control Modes | Manual |

  • Communications, power allocation test mode for site commissioning. Manually control assets and the microgrid system.

Control Modes | Idle |

  • Monitoring only - Cat ECS 400 relinquish control to another site controller.

Control Modes | Off |

  • Off

Cat Remote Breaker Control

  • Utility Protection Functions - American National Standards Institute (ANSI) - Over / Under Voltage (59 / 27) - Over / Under Frequency (81O / U) - Rate of Change of Frequency (ROCOF) (81R) - Sync check (25).
