6 FAQs about [Photovoltaic inverter data collection settings]

Can a PV inverter be set to stand-alone mode?

The PV inverter can be set to stand-alone mode and reduce its feed-in power if this is required by the battery state of charge or the energy demand of the connected loads. To do this, use the integrated frequency-shift power control (FSPC). Selecting the PV Inverter You can use the following PV inverters in off-grid systems.

How is PV system data collected?

The PV system data is collected when the installers apply to the grid operator for a grid connection. Registers developed in order to follow the financial incentives and especially the feed-in tariffs granted to PV systems normally collect DC power information (nominal power of PV modules under standard test conditions STC).

What parameters are required for a photovoltaic system?

For photovoltaics, there are also some specific parameters required (fixed, 1-axis or 2-axis; peak power, inverter power, and retribution obtained). Dynamic data (e.g. energy yield data) is not covered by the database.

What if the SMA PV inverter is not configured for off-grid operation?

If the SMA PV inverter is not configured for off-grid operation ex works, you will need to configure the country data set of the PV inverter to stand-alone mode (see the PV inverter documentation).

Can I use PV inverters in off-grid systems?

You can use the following PV inverters in off-grid systems. You can order all the listed PV inverters with preset off-grid parameters from SMA Solar Technology AG. The PV inverters must be equipped with at least the firmware version given in the table, or a higher version.

Do I need a firmware update for my PV inverter?

The PV inverters must be equipped with at least the firmware version given in the table, or a higher version. If this is not the case, perform a firmware update (see PV inverter documentation). In off-grid systems, the nominal AC power of the PV system must not be more than double the nominal AC power of the Sunny Island inverters.
