6 FAQs about [Solar power generation after transformer shutdown]

When do solar inverters shut down?

To prevent a bad situation getting worse, solar inverters will shut down once grid voltage reaches a set limit. Usually, older inverters have higher set points while most modern ones can reduce their output gradually as grid voltage rises. South Australia Power Networks get over 10 complaints a day about grid over voltage.

What voltage does a renewable transformer use?

Renewable transformers also have different voltages than the standard industrial voltages you might have seen. 800, 630, and 600 are all common voltages used with solar arrays. 800V is more common with European inverter manufacturers; 630V is usually found in larger solar arrays; and 600V is the most common voltage for solar inverters.

Can overvoltage-induced inverter disconnections prevent solar power losses?

Scientists at the University of South Australia have identified a series of strategies that can be implemented to prevent solar power losses when overvoltage-induced inverter disconnections occur, due to voltage limit violations.

What happens if a solar PV system is incorporated into the grid?

When solar PV is incorporated into the grid, power swings occur in the transmission line. The system becomes unstable as a result of power fluctuations. The transmission line impedance is compensated by DTCSC to keep the system steady , (Fig. 7).

What happens if grid voltage is higher than solar power?

Electricity flows from higher voltage to lower voltage. This means if the grid voltage is higher than the voltage produced by rooftop solar, that solar power system will be unable to export energy.

How many times a year does solar power go down?

In August, Richard Chirgwin wrote about how the problem is getting worse. He reported that, according to Solar Analytics, 50% of their customers had their solar energy reduced or shut down at least 50 times a year. That’s an average of about one or more times a week, although these events will be less common in winter when solar output is lower.
