Monitoring system for photovoltaic system

PVI-RS485-MODBUS is the ABB devices family able to convert the proprietary Aurora Protocol to ModBus RTU or ModBus TCP communication protocol.
The PVI-RS485-MODBUS enables ABB inverters to exchange data with third party devices such as controller as well as data logger supporting ModBus (RTU or TCP) communication protocol.
The PVI-RS485-MODBUS is a DIN rail mounted device and can be configured and upgrated locally by simply using a PC (connected to the RS485 port through ABB PVI-USB-RS232-485 Adapter) running a common testing application able to operate as a ModBus master for accessing data in the PVI-RS485-MODBUS connected as slave device.
The PVI-RS485-MODBUS is capable to manage up to 32 ABB string inverters or 32 ABB 55kW inverter modules and, according to the specific product model, it allows customer to manage inverter power control in range of Smart Grid functionalities.
