PHOTOVOLTAIC FIELDS MONITOR
PVM family is used for the measure and the continuous monitoring of the main electric values and phisical of photovoltaic system, on the DC side.
In power stations or in small photovoltaic system, PVM constantly monitors the efficiency of photovoltaic strings. Through the RS485 serial port, PVM-C transmit in real-time current (4-strings), and the voltage field, PVM-S irradiance, temperature, wind speed and any other parameters in the photovoltaic field. Each PVM has 2 additional digital inputs to handle any signals of alarm and LED display for anomaly on strings.
