Grid Failure
The standard measurement and safety procedures integrated into the inverter ensure that
the power feed is immediately interrupted in the event of a grid failure (shut-off by the utility
or damage to lines).

RCMU

RCMU = Residual Current Monitoring Unit
The inverter is equipped with an RCMU according to Austrian standard ÖVE/ÖNORM E
8001-4-712.
It monitors residual currents from the solar module to the inverter grid connection and dis-
connects the inverter from the grid when an improper residual current is detected.
Additional residual current protection may be needed depending on the installation's pro-
tection system or the requirements of the utility company. In this case, use a type B residual
current circuit breaker with a release current of at least 100 mA.
The values provided are standard values. If required, the inverter can be custom-
ized for a specific country.
Depending on the country setup or device-specific settings
