Modbus RS485 RS232 Card for Off Grid Hybrid Inverters | Voltacon

This Voltacon Modbus RTU communication card gives RS485 and RS232/RS485 connectivity to compatible off-grid and hybrid solar inverters. It lets a computer or building management system read and write inverter registers directly, so you get real-time monitoring, remote configuration and control from a connected PC or SCADA system.

Key features

• Protocol, Modbus RTU with RS485 and RS232/RS485 modes
• Protection, surge protection on board
• Configuration, switch between RS232 and RS485 via DIP switches
• Register access, supports reading Holding Registers and writing Registers
• Multi-unit, several inverters can be monitored and controlled at once
• Compatibility, for Voltronic off-grid and hybrid inverters

Applications

Use it for PC-based monitoring and configuration of Voltronic off-grid and hybrid inverters, or to integrate an inverter into a SCADA or building energy management system.

Installation notes

Fully isolate the inverter before fitting the card into its communication slot. Set the DIP switches to RS232 or RS485 mode as needed. Check the inverter's communication manual for the Modbus register map and baud rate settings before commissioning.
