Photovoltaic off-grid inverter withstand voltage data

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.

What is a solar power inverter?

It is a critical balance of system (BOS) component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for photovoltaic arrays and maximum power point tracking systems.

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 a wind power inverter feed into a stand-alone grid?

If wind power inverters feed into the stand-alone grid, design the total nominal power of the AC sources in the stand-alone grid to be no larger than the nominal AC power of the Sunny Island. Allow at least 100 Ah of battery capacity per 1000 W of nominal AC power from the AC sources in the stand-alone grid.

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

The country data set must be set to stand-alone mode in off-grid systems. You can order PV inverters configured for stand-alone mode or you can configure existing PV inverters for stand-alone mode (see Section 4 "Communication Products for Configuring PV Inverters", page 6).

Can sunny island inverters be off-grid?

In off-grid operation, the Sunny Island inverters must be able to limit their output power, if PV inverters are connected on the AC side. This situation can occur when, for example, the battery of the Sunny Island is fully charged and the PV power available from the PV system exceeds the power requirement of the connected loads.
