DEIF ASC-4 Battery Automatic Sustainable Controller

The ASC-4 Battery lets you quickly and easily add energy storage systems (ESS)

such as batteries in greenfield hybrid applications with other DEIF controllers,

providing seamless energy storage in commercial and industrial applications.

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.
