摘要： An apparatus and method for protection in power installations are disclosed. The apparatus includes a power converter (505,605) configured to convert input power to direct-current output power on a power converter output terminal, the power converter comprising a controller (306) and a receiver (507, 607). The receiver provides an enable signal to the controller in response to a presence of a varying signal superimposed on the power converter output terminal. The controller shuts down the conversion of the input power to the direct-current output power if the power converter does not receive the enabling signal from the receiver.

摘要： A method for arc detection in a system including a photovoltaic panel and a load connectible to the photovoltaic panel with a DC power line. The method measures power delivered to the load thereby producing a first measurement result of the power delivered to the load. Power produced by the photovoltaic panel is also measured, thereby producing a second measurement result of power produced by the photovoltaic panel. The first measurement result is compared with the second measurement result thereby producing a differential power measurement result. Upon the differential power measurement result being more than a threshold value, an alarm condition may also be set. The second measurement result may be modulated and transmitted over the DC power line.

摘要： A protection method in a distributed power system including of DC power sources and multiple power modules which include inputs coupled to the DC power sources. The power modules include outputs coupled in series with one or more other power modules to form a serial string. An inverter is coupled to the serial string. The inverter converts power input from the string and produces output power. When the inverter stops production of the output power, each of the power modules is shut down and thereby the power input to the inverter is ceased.

摘要： A junction box assembly 210 for providing an electrical connection to an electrical wire (e.g. bus ribbon 102) attached to a photovoltaic (PV) panel comprises: a lower portion 210 with an entry slot 210b for wire entry; and a raised protrusion 208, over which the wire 102 is bent and formed to be substantially the same shape as the protrusion 208. A clamp 300 may be attached to the lower portion 210 to hold the wire 102 in place for providing the electrical connection. The lower portion 210 may have an elastic, polymeric element 206 disposed between the raised portion and the wire. The raised protrusion itself may have an elastic, polymeric element. The junction box assembly 210 may include an upper portion with a terminal 536 (e.g. spring-loaded) which operatively connects to an electric load (e.g. DC-DC or DC-AC converter, DC motor, battery), wherein the terminal 536 is adapted to be applied under pressure onto the wire 102, thereby conforming the terminal 536 to be substantially the same shape as the protrusion 102. The upper portion may include a diode (e.g. by-pass or blocking) connected to the terminal 536.

摘要： Arcs are detected in a power generation system 201 including a photovoltaic (solar) panel 200 and a load 250 connected to the photovoltaic panel with a DC power line. The power delivered to the load or the noise voltage of the load is measured to produce a first measurement result. The power produced by the panel or the noise voltage of the panel is measured to produce a first measurement result. The first measurement result is compared with the second measurement result to give a differential power measurement result. If the differential power measurement result is more than a threshold value, an alarm condition may be set. The second measurement result may be modulated and transmitted over the DC power line. The power produced by the panel may be measured by an electronic module. The power delivered to the load may be measured by a controller 204 using a sensor 206. The load may be an AC/DC or DC/DC converter. Multiple panels and electronic modules may be connected to form a serial string.

摘要： A distributed power system wherein a plurality of power converters are connected in parallel and share the power conversion load according to a prescribed function, but each power converter autonomously determines its share of power conversion. Each power converter operates according to its own power conversion formula/function, such that overall the parallel-connected converters share the power conversion load in a predetermined manner.
