Abstract
A 'smart' junction box for photovoltaic systems provides electrical measurements of strings of photovoltaic cells to detect premature photovoltaic cell degradation, bypass diode failure, and arcing, and report the same to a central location and/or to provide for automatic disconnection of a given string of photovoltaic cells. The smart junction box also provides general reporting of electrical characteristics to the central system and allows disconnection by command from the central system.
