STRING CONTINUITY MONITORING

摘要

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.

1. A method of monitoring a photovoltaic (PV) installation, said method comprising:
providing at least one PV panel reconnected to a power system after a previous disconnection, wherein said power system does not draw current from said at least one PV panel; determining whether a maintain connection condition is satisfied to maintain connection of said at least one PV panel to said power system; and controlling said connection of said at least one PV panel to said power system based on whether said maintain connection condition is satisfied.
