PV inverter switching time setting

What is a delay time parameter in a solar inverter?

Specifies the delay time for raising abnormal string alarms when the solar inverter detects that a PV string is working with low power. This parameter is mainly used in the scenario where PV strings are shaded for a long time in the morning and evening, and is used to prevent false alarms.

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 long does it take a solar inverter to restart?

When PV module type is set to CPV 1, the solar inverter can quickly restart in 60 minutes if the input power of PV modules drops drastically due to shading. When PV module type is set to CPV 2, the solar inverter can quickly restart in 10 minutes if the input power of PV modules drops drastically due to shading.

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.

How long should a user wait before starting an inverter?

By default, the user needs to wait for at least 4 hours before starting the inverter. Note b: If the maximum feed-in current is not adjusted to a value within the range limit within 15s, the inverter will shut down and report a Power Control Abnormal at Grid Connection Point alarm. If multiple inverters are cascaded, the SmartLogger must be used.

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.
