    Abstract: Circuits integrated or integrable with a photovoltaic panel to provide built-in functionality to the photovoltaic panel including safety features such as arc detection and elimination, ground fault detection and elimination, reverse current protection, monitoring of the performance of the photovoltaic panel, transmission of the monitored parameters and theft prevention of the photovoltaic panel. The circuits may avoid power conversion, for instance DC/DC power conversion, may avoid performing maximum power tracking to include a minimum number of components and thereby increase overall reliability.

    Abstract: A system for providing power from a direct current (DC) source to the power grid. The system includes a first inverter with an input and an output. The input is adapted to connect to the DC source. A first switch disposed between the output and the power grid. A second inverter with a DC terminal and an AC terminal, the AC terminal is adapted to connect in parallel with the output of the first inverter. A battery adapted to connect to the DC terminal of the second inverter. A second switch connected between the DC terminal of the second inverter and the input of the first inverter. The second switch also operatively connects the DC source to the battery. The system may further include a charging circuit adapted to be disposed between the input and the DC terminal and a load adapted to connect to the output.

    Abstract: A photovoltaic power generation system, having a photovoltaic panel, which has a direct current (DC) output and a micro-inverter with input terminals and output terminals. The input terminals are adapted for connection to the DC output. The micro-inverter is configured for converting an input DC power received at the input terminals to an output alternating current (AC) power at the output terminals. A bypass current path between the output terminals may be adapted for passing current produced externally to the micro-inverter. The micro-inverter is configured to output an alternating current voltage significantly less than a grid voltage.

    Abstract: An apparatus of a junction box component housed in a junction box and designed to be coupled to a power generator. The junction box component may include one or more bypass mechanisms configured to bypass one or more substrings of the power generator in a case of malfunction or mismatch between the substring and the remainder of the power generators. The one or more bypass mechanisms may generate heat which may be transferred out of the junction box. The junction box component may be designed to conduct the heat towards the base of the junction box and/or the cover of the junction box. A heat dissipation mechanism may be mounted on the base and/or the cover. A bypass mechanism may bypass the entire power generator.
