Flicker is a problem that occurs when __________
a. A solar photovoltaic system increases or decreases voltage.
b. The voltage in the grid causes the solar photovoltaic panel to create more voltage.
c. The power switch that connects the solar photovoltaic system to the grid turns on and off quickly.
Question 2
Low voltage ride through (LVRT) is ___________
a. The ability of an electrical generation system like a solar photovoltaic system to not fault out when the voltageon the grid gets too low.
b. A special circuit in a solar photovoltaic system generator that ensures that the proper voltage is supplied when the solar photovoltaic system is not connected to the grid.
c. A special circuit in a solar photovoltaic system generator that causes it to trip off when voltage gets too high.
d. All the above are true.
