6 FAQs about [PV inverter power threshold table]

What is the power threshold of a PVSyst inverter?

The Power threshold of most inverters is of the order of 1% or less of Pnom. In the version 5, PVsyst fixes a limit at 0.5%. Many manufacturers contest this limit. In the version 6, this limit is only required when PVsyst has to build an automatic efficiency profile from the Effmax and EffEURO parameters.

What is the default power threshold for triggering inverter shutdown?

The default value is 0. This parameter specifies the power threshold of the grid-connection point for triggering inverter shutdown. The default value is 20. This parameter specifies the duration threshold of high feed-in power for triggering inverter shutdown.

What is a grid voltage threshold & trip time?

The minimum and maximum grid voltage thresholds (in volts) and the trip time in milliseconds or seconds. The trip time indicates the time after which the inverter should disconnect from the grid if the grid voltage is out of range. The minimum and maximum grid frequency thresholds (in Hz) and the trip time in milliseconds or seconds.

How does a PV inverter work?

The second block after the PV array is a basic DC-DC converter of type boost that steps up the voltage from low input voltage, coming from the PV array, into high output voltage, going to the input of the inverter. The input of the boost converter is connected to the PV array in order to achieve the MPP in different atmospheric conditions.

How do I set a power threshold / Pnom lower limit in PVSyst?

The default value in PVsyst is 0.5%. Set the Power Threshold / PNom lower limit parameter to 0.01% so that the PVsyst calculations include power production to essentially zero output for Enphase systems. From the main page click on Preferences and select Edit hidden parameters. Select the Regulators and converters from the Category drop down menu.

What is a good response time for a PV inverter?

For our inverter, as mentioned in Figure 19, the response time to have a good form of the output voltage for electrical loads is 30 ms at the beginning in which the power generated by the PV array is 589 W. Moreover, in this time, the RMS value of the output voltage of the inverter is less than the norm 230 V.
