6 FAQs about [Common photovoltaic inverter parameter settings]

What are the parameters of a PV inverter?

Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.

What parameters should be considered when stringing an inverter and PV array?

Both the maximum voltage value and operating voltage range of an inverter are two main parameters that should be taken into account when stringing the inverter and PV array. PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter.

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).

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.

Why are inverter parameters important?

It is well-known that inverters are a crucial component of photovoltaic systems. Understanding inverter parameters is essential for better system design and equipment selection, ensuring the efficient operation and maintenance of solar power systems.

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.
