At the top, a sun symbol indicates the current solar radiation
trend. If the sun is black or a moon symbol is displayed, the PV
voltage is so low that the inverter is in its idle state. An empty sun
with no rays also indicates that the PV voltage is still too low, with
the inverter in standby mode.
The inverter is represented in the middle of the left-hand section.
If a fault occurs or a message is present, the corresponding sym-
bols flash on the inverter. The bar on the left shows the PV voltage
as a symbol and a digital value. If the bar is completely filled in,
this indicates that sufficient PV voltage is present. The bar on the
right shows the inverter status. If the inverter is feeding power into
the mains, the bar is filled in.
The total energy fed in is shown at the bottom of the display.
Examples of possible displays:

The system is in its normal state, the inverter is feeding power into
the mains.

Solar radiation is sufficient, the inverter is switched off. If the sine
symbol on the inverter is flashing, the inverter has been switched
off due to a fault or it is currently in the synchronisation phase.
