Technical FAQs 4

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.

How do I set up a voltage source inverter?

To get started: Confirm that no power source is connected to the design. Confirm that the output filter is correct for the mode that the device will run in. For example, voltage source inverter uses an LC filter. The L2 and L2N slot must be jumper wired as shown in Figure 11.

What is a voltage source inverter?

Voltage source inverters (VSIs) are commonly used in uninterruptible power supplies (UPS) to generate a regulated AC voltage at the output. Control design of such inverter is challenging because of the unknown nature of load that can be connected to the output of the inverter.

What is voltage-reactive power (VAR) mode?

2. Voltage-reactive power (“Volt-VAr”) mode In this mode, the solar PV system adjusts its reactive power injection (or absorption) based on the actual voltage, if the actual voltage is outside of a specified dead band. A typical control characteristic of Volt-VAr mode is shown in the figure.
