DEIF ASC-4 Battery Energy source, power source, or droop mode

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.
