3.8. System communication
3.8.1. Communication with external EMS
The energy exchange (charge/ discharge) of the system can be managed by an Energy Management System (EMS) that
performs remote operations.
This EMS will pilot the PMS using the Modbus TCP / SunSpec protocol.
The connection is realized with an Ethernet RJ45 cable. The C-Cab IP address will be defined during commissioning.
Socomec is member of the SunSpec organization.
The SunSpec specifications are available on the SunSpec site https://sunspec.org/ .
