<p>A protective circuit for an electrically floating photovoltaic array including a plurality of strings, each string including one or more photovoltaic modules connected in series, the plurality of strings being connected in parallel to supply electrical power from the photovoltaic modules to a load. A first string of the plurality of strings further includes two diodes connected in series, with one or more of the photovoltaic modules connected in series between the two diodes, to prevent a harmful reverse current through at least one photovoltaic module in the event of a multiple earth fault.</p> |
