10.2 Measurement Channels

In the measurement channels, the measured values of the inverter are shown on the display. In
addition, you can read out a series of measurement channels and messages of the inverter via special
communication devices (e.g. Sunny WebBox) or a PC with corresponding software
(e.g. Sunny Explorer).

Explanation
High DC input voltage
The inverter has detected a DC input voltage
that is too high for safe operation.
Disturbance
The inverter has detected an internal fault that
interrupts normal operation:
ground-fault
The inverter has detected a ground-fault. The
inverter will not restart automatically after
detecting a ground-fault.
Corrective measures:
• Check the PV plant for ground-faults
(see Section 11.6).
Initialization
The inverter is initializing. The DC current
available from the PV array is not sufficient for
normal operation. Data transmission is not
possible during initialization.
Standby
The inverter is in standby mode. The DC input
voltage is too low for operation.
