20�4 Alarm
(only Solar-Log 1000 and 2000)
The Solar-Log™ continuously monitors its internal alarm contact. If this contact is opened, it sets off an
alarm which can be indicated in various ways. In the Alarm tab, the alarm contact can be activated and
different types of notification can be configured.

Here you have the option to perform an alarm test.
20�5 Power & Failure
Performance monitoring is based on a comparison of the power out from all of the inverters, including
individual trackers in the case of inverters with more than one tracker or, as the case may be, sensors. If
the target power deviates from the actual power by more than a certain tolerance (= min. feed-in power),
a notification can be sent by e-mail and/or text message (SMS) after the selected fault duration has been
reached.
If an individual module loses power, the string power for the same level of irradiation will drop, and can
thus be detected and reported.
Power comparison always works reliably, even if the weather is cloudy. The important thing is that all mod-
ules should not be overshadowed. Therefore, the monitoring period should be scheduled for periods when
there are no shadows.
As power measurement in the inverter is very inaccurate under a certain threshold, a minimum percentage
value can also be specified below which monitoring is interrupted.
