Solar power generation output current is extremely short circuit

Technical Note – Short-Circuit Currents in SolarEdge Three Phase

Grid failures may cause photovoltaic inverters to generate currents ("short-circuit currents") that are higher than the maximum allowable current generated during normal operation. For this reason, grid operators may request short-circuit current ratings from vendors in order to prepare for failure scenarios.

Don''t Short Circuit A Solar Panel (Do This)

A short circuit happens when an excessive current runs through an unintended path – you overload the system. Yes, you can short a solar panel, but you likely won''t cause damage to the panel in this way. A solar panel is rated by its short circuit current and was likely shorted during testing. If your panel was damaged after you shorted it
