FAQS 4
How to provide voltage support in PV inverter?
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.
What does a PV inverter do?
The inverter establishes the connection between the photovoltaic (PV) system and the electrical grid and holds paramount significance. These inverters incorporate transformers to regulate the direct current (DC) voltage supplied to the inverter and to provide isolation between the PV system and the grid 8, 9.
How does a solar inverter work?
The DC voltage generated by the solar panels is fed into the single-input, multiple-output boost converter, which increases the voltage to the required level before supplying it to the 53-level inverter.
What is over current protection mechanism in PV inverter?
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. The triggering of over current protection will lead to disconnection of inverter from the grid which is unfavourable during LVRT period.
