摘要： 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.

摘要： A direct current (DC) power combiner (19) operable to interconnect multiple interconnected photovoltaic strings (8). The DC power combiner may include a device adapted for disconnecting at least one photovoltaic string from the multiple interconnected photovoltaic strings, each photovoltaic string connectible by a first and second DC power line. The device may include a differential current sensor (RCD1) adapted to measure differential current by comparing respective currents in the first and second DC power lines. A first switch connected in series with the first DC power line. A control module (10) operatively attached to the differential current sensor and the first switch. The control module may be operable to open the first switch when the differential current sensor measures the differential current to be greater than a maximum allowed current differential, thereby isolating the first DC power line from the DC power combiner and disconnecting the photovoltaic string from the interconnected photovoltaic strings.
