Modbus Card with RTU protocol

 This card establishes communication between the solar inverters (or UPS) and your computer. 

Main Features of the Card.

  • Modbus RTU protocol
  • There is surge protection on the board.
  • Configurable between RS-232 and RS-485 using the dip-switches
  • The MODBUS function includes read Holding Registers and write Registers.
  • Multiple inverters can be monitored and controlled in real time using RS-232/RS-485 communication port

This card will establish communication between your UPS, solar PV inverter (on-grid and off-grid) and your computer (PC) using the MODBUS protocol.

Using the  Modbus card, a hybrid solar inverter is connected to energy meter with RS485 communication port. This communication strategy will control the self-consumption via Modbus card to control power generation and battery charging of the inverter.
