Starting the Self-Test (for Italy and Dubai)
The self-test is only required for inverters that are to be commissioned in Italy or Dubai. The Italian
standard CEI 0-21 and the DEWA (Dubai Electricity and Water Authority) stipulate that all inverters
that feed into the utility grid are equipped with a self-test function. During the self-test, the inverter
will consecutively check the reaction times for overvoltage, undervoltage, maximum frequency and
minimum frequency.
The self-test changes the upper and lower disconnection values for each protective function on a
linear basis for frequency monitoring and voltage monitoring. As soon as the measured value
exceeds the permitted disconnection threshold, the inverter disconnects from the utility grid. In this
way, the inverter determines the reaction time and checks itself.
After the self-test has been completed, the inverter automatically switches back to feed-in operation,
resets the original disconnection conditions and connects to the utility grid. The test takes
approximately three minutes.
Requirements:
☐ The country data set of the inverter must be set to
CEI 0-21 internal
