Solar Radiation and Panel Temperature Sensor
DB2-WM2
 |
Key features
|
The DB2-WM2 is a device of the ZB-Connection family. It detects and transmits to a Gateway of the ZB-Connection products family of Digitron® the value of solar radiation measured by compensated temperature photodiode, the energy theoretically producible by a photovoltaic installation according to the solar radiation and the module
temperature measured by contact probe.
The energy theoretically producible provides normalization with a settable parameter that takes into account the efficiency of the panels used and the rated power plant.
It is powered by solar cell 5V 100 mA assisted by lithium battery for the night periods and if lack of sunshine.
