5.3.6 Failures
As long as the ERROR LED isn’t illuminated,

operating normally!

insufficient, for instance at night, the
Sunmaster switches off automatically and the
display does not show any information. This is
a normal situation!
Figure 5-7: representation of a failure
The operation of the Sunmaster is controlled and checked
by a microprocessor. If an error occurs, it is detected by
the apparatus itself: the red ERROR LED illuminates or
blinks. The cause of error is displayed by means of an
error code. See figure 5-7. Refer to chapter 6 for
explanation of the error codes.
5.3.7 Power limitation
In some cases a power limitation function must be
activated on the inverter. The XS inverter power limitation
function can be activated via a datalogger like the
DataControl Pro and Premium II. These dataloggers are
connected by means of the RS485 network. If the grid
operator activates the power limitation function, the
inverters will limit their power to the power percentage set.
The display shows “PM” and the percentage to which the
power is limited. For instance PM 80 means, the power is
80% of its maximum now. If no power limitation command
has been received for over 10 minutes, the inverters return
to normal operation.
