An essential but underrepresented component of the systems is the inverter duty transformer. These transformers act as a connection between the inverter and the grid or the load so as to
For the grid-tied inverter to deliver the desired power into the grid, many factors should be taken into account, including the dc input voltage, the grid voltage, component current rating, and the output inductor. The inverter output voltage amplitude is limited by the input dc voltage source to prevent the over modulation problem.
The average grid voltage (UAC) at the inverter as measured over a period of 10 minutes is limited to a maximum of 253 V in Germany according to DIN VDE 0126-1-1. If the inverter records that the 10-minute average exceeds this voltage limit, or if the 260 V limit is temporarily exceeded, it will switch off immediately.
If the inverter records that the 10-minute average exceeds this voltage limit, or if the 260 V limit is temporarily exceeded, it will switch off immediately. The inverter will display a grid error message if this occurs.
Under grid voltage sags, over current protection and exploiting the maximum capacity of the inverter are the two main goals of grid-connected PV inverters. To facilitate low-voltage ride-through (LVRT), it is imperative to ensure that inverter currents are sinusoidal and remain within permissible limits throughout the inverter operation.
When a fault (such as a short circuit, flickering, or loss of grid power) occurs on the grid, even if it is transient in nature, the conventional grid-tied PV inverters automatically cut themselves off from the grid. The inverters are configured in this fashion to prevent damage from transients of over current or over voltage.
To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.
