BOM-TS-485 – Back of Module Temperature Sensor
The BOM-TS-485 is an accurate and reliable back of module temperature sensor. Designed to specifically measure the temperature of the rear of photovoltaic solar panels, the BOM-TS-485 provides key insights into panel performance.
As a PV panel’s efficiency is affected by temperature, measuring and understanding this information helps form a greater understanding of your panel’s performance. The PT1000 Class B sensor (EN 60751) can be easily installed on the back of solar panels. Once installed the sensor will measure the temperature of the surface of the panel, using the RS-485 Modbus communications this data is then transmitted to your datalogger or SCADA.
Ideal for all sizes of PV solar installations from small rooftop to utility-scale solar farms.
