6 FAQs about [PV inverter voltage parameter settings]

How do I set inverter parameters?

To set inverter parameters, tap Settings. For details about the parameters, see FusionSolar App and SUN2000 App Device Commissioning Guide. You can also scan the QR code to obtain the document. The output current of the PV power system can be limited or reduced to ensure that the output current is within the specified range.

Do I need to set a string connection parameter for a solar inverter?

You do not need to set this parameter if each PV string is separately connected to a solar inverter. The solar inverter can automatically detect the connection mode of the PV strings. Set this parameter to All PV strings connected if all PV strings are connected in parallel and then connected to the inverter in parallel.

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 happens if inverter parameters are incorrectly set?

If the power adjustment parameters and grid-tied point control parameters are incorrectly set, the inverters may not connect to the power grid as required. In these cases, the energy yield will be affected. To set inverter parameters, tap Settings. For details about the parameters, see FusionSolar App and SUN2000 App Device Commissioning Guide.

Can a professional set the grid parameters of the inverters?

Only professionals are allowed to set the grid parameters, protection parameters, feature parameters, power adjustment parameters, and grid-tied point control parameters of the inverters. If the grid parameters, protection parameters, and feature parameters are incorrectly set, the inverters may not connect to the power grid.

What is the parameter name & configurable value for a PV inverter?

The parameter name and the configurable value depend on the PV inverter and the communication product in use. In battery-backup systems, you operate the PV inverters with the locally typical country data set for grid-tie PV systems in accordance with UL1741.
