Abstract:
1. A circuitry arrangement for a solar power plant comprising: at least one generator terminal configured to connect to a photovoltaic generator; a grid terminal configured to connect to an AC power grid; at least one transformerless inverter configured to feed electric power from a photovoltaic power generator when connected to the at least one generator terminal into an AC power grid when connected to the grid terminal; first electric lines extending between the at least one generator terminal and the at least one inverter, and second electric lines extending between the at least one inverter and the grid terminal; a galvanic isolation provided in all second electric lines carrying a current between the at least one inverter and the grid terminal; and an offset path leading from one of the first and second electric lines on a side of the galvanic isolation opposing the grid terminal to a reference potential, the offset path comprising:
