Explanation/remedy
Because the temperatures inside the unit are too high, the de-
vice reduces its power to prevent damage to the device. Note
the technical data. Ensure that the convection cooling is not
impeded from the exterior. Do not cover the cooling fins.
› Ensure sufficient cooling of the device.
› Remove any foreign bodies that may be on the device.
› Clean the cooling fins
A generator string is disconnected from the device due to a de-
fective fuse. Establish the cause of tripping by measuring all DC
strings with a clip-on ammeter. - If there is no current flowing
in a string, then the associated DC fuse is defective.
Check the no-load voltage and layout of the PV generator. Re-
place the damaged modules if necessary.
› Replace the PV fuse with a fuse size that is of the same type.
Explanation
– The fault relay has switched.
– Feed-in was ended due to a fault.
– The fault relay releases again.
– The device feeds back into the grid again after a country-
specific time period.
