The DEIF ASC-4 Battery is a highly configurable sustainable energy storage controller that allows seamless integration of an ESS in greenfield applications with other DEIF controllers such as the AGC-4 Mk II advanced genset controller and other sustainable controllers in our ASC-4 range.
Wide range of control strategies
The ASC-4 Battery lets you store and use green power from PV panels and wind turbines. The controller handles charging and discharging as required by the operating scenario, based on state of charge control of the ESS or using Schedular-Command timers that allow you to define which sources to charge from, and when. It includes control strategies such as peak shaving, load take-over, fixed power, automatic mains failure (AMF), and mains power export (MPE), allowing it to be used for a wide range of applications. You can define and change the priority of connected power sources.
Energy source, power source, or droop mode
The ASC-4 Battery is suitable for grid-forming or grid-following applications, and it supports energy source or power source functions. It is also able to run in droop mode (acting as a virtual synchronous generator) if the ESS supports this. The ASC-4 Battery can switch operating modes very quickly as required. It supports grid/power quality support with active or reactive power, spinning reserve capability (reducing the number of gensets running), frequency and load response, and load control.
Built-in power metering
The built-in power metering feature of the ASC-4 Battery measures busbar voltage, current, and frequency before and after the breakers. Operation and mode switches can be configured to be based on these readings, for example carrying out mode switches based on voltage and frequency changes.
Full compatibility with wide range of equipment
The ASC-4 Battery can communicate with a BCU (battery control unit) or directly with a BMS (battery management system) and PCS (power control system) over Modbus, allowing it to be used with a wide range of ESSes. It is designed for full compatibility with DEIF controllers, allowing you to set up an EMS quickly and efficiently. For an updated compatibility list for the controller, see Application Notes on the Documentation tab.
M-Logic provides flexibility and customisability
The setup of the ASC-4 Battery can quickly and easily be reconfigured as needed using the user-friendly M-Logic tool (part of DEIF’s free PC utility software offering). This allows the controller to be customised to a wide range of local applications.
Emulation feature provides safe system testing
The built-in emulation feature of the ASC-4 Battery 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 system is to turn on your controller and connect communications.
