Abstract
A system and method of monitoring a photovoltaic (PV) installation includes providing a string of multiple panel interface device enabled PV panels; operatively connecting an inverter to the string; operatively connecting at least one PV panel to the string; discharging an input capacitance of the inverter; comparing a current in the string to a predetermined current threshold value; and controlling connection of the at least one PV panel to the string based on the comparing of the current in the string to the predetermined current threshold value. A panel interface device may be used to discharge the input capacitance of the inverter.
