User information

The guarantee is for 1 year from the date of the invoice for the intended use. M&T does not accept any liability
for possible losses or damage due to the incorrect usage of the sensor. Liability for consequential damages is
excluded.
Special note: The housing for the Si sensors is not allowed to be opened by the installer or user because, as a
consequence, the housing will no longer be sealed after it is closed. If the housing is opened, the
manufacturer's warranty will be rendered void.

Maintenance

Scope of the regularly check (at least every 2 years): Cleaning of solar cell, external damage, mechanical
fastening, cable laying and any damage to the cable.
In the report IEA-PVPS T13-03:2014 "Analytical Monitoring of Grid-connected Photovoltaic Systems" an
interval of 1 to 2 weeks is recommended.
Should damage be found that degrades the function or safety, the sensor is to be replaced.
A recalibration is recommended at least every 3 years.
