MODBUS Card for Energy Meter


This card will establish communication between your UPS, solar PV inverter (on-grid and off-grid) and your computer (PC) using the MODBUS protocol. It is also the essential component for Hybrid Solar System with grid support and energy meter. 

Main features of the card:

  • Implements MODBUS RTU protocol
  • Enables MODBUS functions including read Holding Registers and write Registers
  • Communication via RS232 and RS485 interface
Control of Self Consumption and Battery Charging - Suitable for single and three-phase systems with energy meters

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.

The modbus card is required with 3kW , 5kW and 10kW Hybrid Inverters Infinisolar and Voltasol. Modbus card regulates the self-consumption using the readings from the energy meter. It is also controls the power generation and battery charging process of the inverter
