Selection of the measurements
Selection of the measurements to be shown in the status display.
The following measurements can be selected:
n Output power: output power of the inverter
1)
n Current day yield: day yield since 0:00
n PV voltage: the voltage supplied by the solar modules
n PV current: the current supplied by the solar modules
n Grid voltage
1)
n Grid current: the current fed into the mains grid
n Grid frequency
n Internal temp.: the internal temperature of the inverter
n Derating: cause for derating
2)
n Max. daily power: the maximum power supplied in the cur-
rent day
3)
n Abs. max. power: the maximum power ever fed into the
grid
3)
n Max. daily yield: the maximum daily yield achieved
3)
n Operating hours: The operating hours during which the
device has been connected to the grid (including nighttime
hours).
n Total yield: yield since commissioning
n CO
2
saving: CO
2
savings achieved since commissioning
1)
Measurement is always displayed (cannot be switched off)
2)
Possible causes:
n Internal temperature too high
n User default
Power limiter
n Frequency too high
n Controlled by grid operator (feed-in management)
n Delayed increase in power after starting
3)
Can be reset to 0 via Settings ▶ Reset max. vals.
Acoustic alarm
An acoustic alarm sounds (approx. 4.5 kHz) when an event message
