METHOD AND ARRANGEMENT FOR GROUNDING PHOTOVOLTAIC SYSTEM AND PHOTOVOLTAIC SYSTEM

摘要

A method and an arrangement for grounding a photovoltaic system comprising one or more photovoltaic panels configured to provide a DC output, the arrangement comprising a first switch (S1 ) and a first impedance (Z1) connected in series between a first pole (P1) and a second pole (P2) of the arrangement, a second switch (S2) connected in parallel to the first impedance (Z1), and control means (42) configured to switch on the second switch (S2) after the first switch (S1) is switched on.
