be detected by the control unit and the number of inverters
found during the scan will be correspondingly lower than the
total number of installed inverters. As soon as solar ener-
gy levels are high enough, the inverters in question will be
found by the scan.
4. The number of inverters found must always correspond to
the number of inverters of which the LED is lit or flashing.
5. The system checks for configuration changes once every
minute. New units that are found are added to the system. A
warning (system message ) is displayed for units that have
been inactive for too long (48 hours).

Operation

The control unit operates fully automatically. During normal
operation, the display shows the total amount of energy deli-
vered by the system. If any irregularities are detected, system
messages (error codes) appear in the display. See Chapter 8
'Problem solving', 'Display messages' for explanations of
the error codes.
NOTE
During periods of low solar energy (e.g. in the mornings or
in the evenings), messages referring to inverter start-up and
switching can appear. This is normal and the messages will
disappear of their own accord after a while.
