6 FAQs about [Causes of short circuit in solar photovoltaic power generation]

Why are PV inverters able to supply more short circuit current?

In principle the PV inverters are able to supply more short circuit current during fault scenarios than only 1 p.u. reactive current due to current reserve margin of the inverter system. The control is able to limit the current injection during faults to the nominal but also to an overload current limitation of the generation system.

What is short-circuit current in a solar cell?

The short-circuit current is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar cell is short circuited).
