6 FAQs about [Hanergy photovoltaic inverter voltage adjustment]

What is power factor fix control in a solar inverter?

If the PV plant is required to generate a constant power factor at the grid-tied point and the solar inverter is required to adjust the real-time reactive power based on the preset power factor, set this parameter to Power factor fix control.

What is P(V) – power voltage?

P(V) – Power Voltage: This is used when voltage-based power reduction is required. This defines a linear graph set by six points (available from inverter CPU version 3.1808). The inverter de-rates power according to the defined graph, until the voltage reaches the trip value and the inverter disconnects.

How to configure the characteristic curve in a solar inverter?

Configure the characteristic curve under instructions from professionals to ensure that the solar inverter works properly. The Q-U characteristic curve control mode is to dynamically adjust the ratio Q/S of output reactive power to apparent power in accordance with the ratio U/Un (%) of the actual grid voltage to the rated grid voltage.

What are inverter settings?

Inverter Settings 1. To set output voltage of inverter - This is normally 230 Vac. Possible values 210V ~ 245V. 2. Used to enable/disable the internal ground relay functionality. Connection between N and PE during inverter operation. - The ground relay is useful when an earth-leakage circuit-breaker is part of the installation.

Can a solar inverter run with only active power output?

If the PV plant is not required to adjust the voltage at the grid-tied point or perform reactive power compensation, solar inverters can run with only active power output. In this case, set this parameter to No Output. Before setting this function, ensure that the DI port is not occupied. Otherwise, the setting fails.

How does a PV inverter work?

One method used for this purpose is limiting the export power: The inverter dynamically adjusts the PV power production in order to ensure that export power to the grid does not exceed a preconfigured limit. To enable this functionality, an energy meter that measures export or consumption must be installed at the site.
