Position Symbol Explanation
E - When output voltage is displayed: line conductors between
which the output voltage is present
When output current is displayed: line conductor to which the
output current is allocated
F Utility grid
G - Event number of an error on the utility grid side
H - Output voltage or output current of the respective line conduc-
tor
I - Event number of an error in the inverter
K Grid relay
When the grid relay is closed, the inverter feeds into the utility
grid.
When the grid relay is open, the inverter is disconnected from
the utility grid.
L Inverter
M - Input voltage or input current of the respective line conductor
N - Event number of an error on the PV array side
O - Text line to display event and error messages
P PV array
Q - Diagram with the power curve of the last 16feed-in hours or
energy yields of the last 16days
