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.
