Technical FAQs 4

Are communication and control systems needed for distributed solar PV systems?

The existing communication technologies, protocols and current practice for solar PV integration are also introduced in the report. The survey results show that deployment of communication and control systems for distributed PV systems is increasing.

What is EMS communication?

EMS communication refers to the exchange of data and instructions between the Energy Management System and various components within a BESS container. The EMS serves as the central intelligence hub, orchestrating the operation of batteries, inverters, monitoring devices, and other subsystems to achieve optimal performance objectives.

What is Power Conversion System (PCS) and Energy Management System (EMS)?

Power Conversion System (PCS): Think of the PCS as the translator. It converts electricity between alternating current (AC) and direct current (DC), facilitating the charging and discharging of the battery. Energy Management System (EMS): The EMS is the brain of the operation.

How do PCs and EMS work together?

For the PCS and EMS to work in harmony, they need a reliable communication channel. This is where RS485 and Modbus come into play: RS485: A robust serial communication standard that allows multiple devices to communicate over long distances, making it ideal for industrial settings.
