The following Fronius inverters can be connected to a ripple control receiver via a
distributor (coupling relay):
-
Symo GEN24
-
Primo GEN24
-
Tauro
-
SnapINverter (only devices with Fronius Datamanager 2.0)
IMPORTANT!
The "4-relay mode" setting (see Connection diagram - 4 relay andI/O power
management settings - 4 relays) must be enabled on the user interface of each
inverter connected to the ripple control receiver.
Autotest
(CEI 0-21)
Description
The "Autotest" can be used to check the protection function required by Italian
standards for monitoring the voltage and frequency limit values of the inverter
during commissioning. In normal operation, the inverter constantly checks the
current voltage and frequency actual value of the grid.
After starting the autotest, various individual tests run automatically one after
the other. Depending on network conditions, the duration of the test is about 15
minutes.
IMPORTANT!
The inverter may only be commissioned in Italy after an autotest has been suc-
cessfully performed (CEI 0-21). If the autotest is not passed, feeding energy into
the grid is not permitted. Once the autotest is started, it must be completed suc-
cessfully. The autotest cannot be started during backup power operation.
U max Test for checking the maximum voltage in phase conductors
U min Test for checking the minimum voltage in phase conductors
f max Test for checking the maximum grid frequency
f min Test for checking the minimum grid frequency
f max alt Test for checking an alternative maximum grid frequency
f min alt Test for checking an alternative minimum grid frequency
U outer min Test for checking the minimum external voltages
U longT. Test for checking the 10-minute mean voltage value

Note on the autotest
The limit values are set in the "Grid Code" menu.
The access code for the "Grid Code" menu corresponds to the installer code
(PROFI menu) and is only made available after a written request to Fronius. A
corresponding application form is available from the national technical support.
