Dust and dirt can silently reduce PV output every day. In this video, we show you how to unbox, install, and commission the SEVEN Automatic Soiling Sensor (3S-SMS-MB series) so you can measure real soiling losses in line with IEC 61724-1 and plan cleaning based on data—not guesswork.
What will you see in the video?
You will get a complete, step-by-step walkthrough, including:
- What’s inside the box: irradiance sensors, water tank, pump, and electronic panel
- How to wire power and communications: Modbus / gateway connection and first access to the configuration tool
- How to start measuring: setting cleaning cycles, launching measurements, and verifying correct operation
- Installation best practices: positioning, inspection routines, and when to recalibrate over time
Why is the SEVEN Automatic Soiling Sensor important for your PV plant?
Once installed, the Automatic Soiling Sensor helps you:
- Track daily soiling ratio and associated energy losses
- Optimize cleaning schedules to maximize yield
- Reduce unnecessary O&M costs while protecting performance
How do you commission the 3S-SMS-MB sensor after watching?
After following the tutorial, you will be able to:
- Mount the sensor correctly in the field
- Connect power and data communication
- Configure coordinates, cleaning and measurement intervals
- Begin recording soiling data and trending losses in your monitoring platform
For full technical information, please refer to the datasheet and the user manual.
Frequently Asked Questions (FAQ)
1- Does the 3S-SMS-MB Automatic Soiling Sensor comply with international standards?
Yes. The 3S-SMS series is designed to measure soiling losses according to IEC 61724-1.
2- What data will I get from the automatic soiling sensor?
You will obtain various data including soiling ratio, clean and soiled cell irradiance values, water tank status, internal temperature values and stable data counter measurements.
3- How often should I recalibrate or inspect the SEVEN Automatic Soiling Sensor?
Periodic inspection is recommended as part of routine O&M. Recalibration frequency depends on site conditions and your internal QA plan.
According to the IEC 61724-1:2021 standard, the monitoring system should be inspected at least once a year, and preferably at more frequent intervals.
