6 FAQs about [Photovoltaic inverter protection setting list]

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 do PV inverters support grid frequency?

Grid frequency support is achieved by adjusting inverter real power output. This functionality is limited with PV inverters because the inverters are following the DC energy provided to them by the sun. For a grid high frequency event, PV inverters can be easily set to reduce active power to help reduce the grid frequency.

What causes PV isolation protection?

The causes of "PV Isolation Protection" are mainly divided into three categories: external environmental factors (increased environmental humidity), system factors (poor system ground insulation), inverter factors (DC line insulation detection and protection threshold is too small).

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.

Can I set the grid protection values on my SolarEdge inverter?

Setting the grid protection values is prohibited unless explicitly approved by the grid operator. This feature is offered to you as a convenience, and SolarEdge disclaims all responsibility for any implications of modifying the grid values of the inverter.
