Automatic genset controller (ACG-4)

The automatic genset controller (AGC-4) can be used as a single genset controller, or several AGCs can be connected in a complete power management system for synchronising projects, islanded or paralleled to the mains.

The generator controller is ideal for mission-critical applications such as hospitals and data centres, and it is capable of delivering backup power in only six seconds.

System testing in a safe environment

DEIF’s emulation solution is a standard in the automatic genset controller (AGC-4) that enables you to interact with the controller in a controlled and safe environment without risking to damage any equipment. All you need to do to perform a complete test of your power management system is to turn on your controller and connect communications.

Intuitive touchscreen puts control at your fingertips

The intuitive, pre-programmed touch display keeps integration time short and makes the automatic genset controller (AGC-4) very user-friendly and will provide you with a smooth and accurate user-experience. The display can be adapted to your needs using an array of control elements, and the tablet-like functionality allows you to operate and configure your genset by swiping, tapping and scrolling. 

Emission standards and grid code requirements

The automatic genset controller (AGC-4) meets the Tier 4 Final standards, and the controller complies with the majority of requirements for parallel to grid operation, including German VDE 4110/4105, European EN50549-1/2 and United Kingdom ENA G99 standards. Both protections and grid support functions are included, giving you a “single controller fits all” solution.

Remote communication and control

The automatic genset controller (AGC-4) supports serial communication protocols including Modbus (RS-485, USB, and TCP/IP) and Profibus. This feature allows you to supervise and control your genset/plant from a remote location. 

Backup power in six seconds and ideal for mission-critical applications

With its integrated close before excitation (run-up synchronisation) feature, the automatic genset controller (AGC-4) secures backup power in impressive six seconds. Combined with the option of having hot standby controllers/dual redundancy on all positions, the AGC-4 is ideal for all types of mission-critical power applications, e.g. data centres, hospitals, airports, and fish farms.

Unique rental genset applications

The controller has been designed with ease of operation in view. The automatic genset controller AGC-4 features up to four parameter settings which is switchable with just a tap on front the touchscreen. You can easily set and lock parameters to ensure full protection of your rental equipment. AGC-4 comprises the unique feature EasyConnect meaning that the controller automatically detects and align all gensets.

Hybrid applications

AGC-4 is plug’n’play compatible with DEIF’s ASC-4 hybrid controller for easy integration of diesel genset applications into a variety of hybrid installations. The market-leading solution maximises sustainable power penetration while always securing a sufficient amount of spinning reserve in case the photovoltaic (PV) production drops.

Available standard modes:

Island mode: Power plant with synchronising generators or a stand-alone generator. Also applicable in critical power plants.

Automatic Mains Failure: Critical power/emergency standby plants, black start generator.

Fixed power: Power plant with fixed kW set point (including building load).

Peak shaving: Power plant where generator supplies peak load demand paralleled to the mains.

Load takeover: Plant mode where the load is moved from mains to a generator, for example, peak demand periods or periods with the risk of power outages.

Mains power export: Power plant with fixed kW set point (excluding building load).

Remote maintenance: Used when the generator has to supply the load while a distribution transformer is disconnected for service.

All modes are configurable, and it is possible to change the plant mode on the fly both in single and in power management applications.
