Description
(CEI 0-21)
The
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.
