Solar radiation sensor with temperature sensor 3S-2IS

RS485Modbus RTU

This Irradiance Sensor Model’s designation is 3S-2IS. It is specially developed to calculate the Performance Ratio (PR) for the dual orientation PV plants, as it calculates the average irradiance value as per the number of panels in each direction. Installation directions of panels in PV power plants and the number of panels in these directions may be different. The user will be able to set the number of panels in each orientation for the correct calculations. 3S-2IS special design allows simultaneous connection of two Irradiance Sensors, two Module Temperature Sensors, an Ambient Temperature Sensor, and a Wind Speed Sensor. The number of panels in both directions, to which the sensors are connected, is entered into the electronic card via 3S-2IS Configuration Interface. The total effective irradiance and total effective module temperature can be calculated and communicated to the datalogger via Modbus RTU protocol. By using these values, the accurate Performance Ratio can be calculated in the monitoring systems.
