String Monitoring Device

Tricheck (Isolated-Shunt based String Monitoring Device)

Optimize your PV power plants performance with our TRICHECK isolated-shunt based string monitoring device which measures string currents and voltages and transfer them to the SCADA through MODBUS communication protocol over an RS485 network. The shunt resistors used offer better accuracy and reliability in current measurement. The TRICHECK comes in 8, 16 & 24 channel cards making it suitable for a wide range of string configurations.
