RCMU

cap. = capacitive
1) The values provided are standard values. If required, the inverter can be custom-
ized for a specific country.
2) Depending on the country setup or device-specific settings
(ind. = inductive; cap. = capacitive)
3) PCC = interface to the public grid
4) Maximum current from inverter to solar module when inverter is experiencing an
error
5) Assured by electrical design of the inverter
6) Peak current when turning on the inverter
Circuit for Preventing Stand Alone Operation
The inverter has a permissible circuit for preventing stand alone operation.
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 = 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.
