4. Introduction
EKO’s Ventilation Unit MV-01 can be used in combination with MS-80 pyranometer models (MS-80, MS-80A and
MS-80M). The MV-01 will reduce the need for maintenance and assures the availability of solar irradiance data
when deployed in cold climate regions or desert environments. Due to the compact and integrated design with the
MS-80 pyranometer, the heating and airflow dynamics are optimized. The power consumption of the ventilator is
only 1.9 Watts, which makes it suitable for solar powered systems. When the heater is activated the total power
consumption will be about 8.9 watt, which is sufficient to prevent snow and ice deposition on the sensor (dome and
sun screen).
The pyranometer with ventilator can be mounted in horizontal or tilted plane, which make it suitable for PV
monitoring applications. The Ta c h o output provides a data pulse to monitor the fan speed.
For the pyranometers operated in harsh environments, the irradiance measurements can be easily affected by
environmental factors. In such case the MV-01 will keep the pyranometer dome free of dew, ice and snow. In
combination with the MV-01 ventilator the best possible measures are taken for reliable unattended operation.
4-1. Main Features
Low power consumption (power consumption: 8.9W, fan 1.9W, heater: 7W)
Wide range of operating temperature (-40℃to +70℃), the MV-01 can be operated in many different
areas of the world.
Overheating protection trough temperature fuse
Using the ventilation with long expected life has made possible to offer 2-year warranty.
By measuring the rotation signal (pulse signal) of the MV-01, the rotation frequency of the fan can be
monitored.
