6.3.2 Overview
If none of the three buttons is pushed for 120 seconds, the display returns automatically
to the Overview menu showing the three most important values as well as the current
operating status.
6.3.3 Measured values
The current inverter measured values can be accessed in the “Measured values” menu.
NOTE
The inverter measured values are not suitable for billing purposes or calculating ef-
ciency. The measuring error may amount to up to ±5% depending on the measured
value. Only the measured values of a calibrated electricity meter are decisive for billing
purposes.
The following measured values can be accessed:
