4 Frequently Asked Questions about "Standard parameters of photovoltaic off-grid inverter"

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.

How can I order a PV inverter with preset off-grid parameters?

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. If this is not the case, perform a firmware update (see PV inverter documentation).

How do I change grid-relevant parameters in the PV inverter?

To change grid-relevant parameters in the PV inverter after the first ten operating hours, you will need a special access code, the SMA Grid Guard code. The application form for this personal access code is available in the download area at, in the "Certificate" category of the respective PV inverter.

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).
