Patent number: 11962243Abstract: A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.Type: GrantFiled: June 10, 2021Date of Patent: April 16, 2024Assignee: Solaredge Technologies Ltd.Inventors: Meir Adest, Lior Handelsman, Yoav Galin, Amir Fishelov, Guy Sella

Publication number: 20240048097Abstract: A method of signaling between a photovoltaic module and an inverter module. The inverter module is connected to the photovoltaic module. In an initial mode of operation an initial code is modulated thereby producing an initial signal. The initial signal is transmitted from the inverter module to the photovoltaic module. The initial signal is received by the photovoltaic module. The operating mode is then changed to a normal mode of power conversion, and during the normal mode of operation a control signal is transmitted from the inverter to the photovoltaic module. A control code is demodulated and received from the control signal. The control code is compared with the initial code producing a comparison. The control command of the control signal is validated as a valid control command from the inverter module with the control command only acted upon when the comparison is a positive comparison.Type: ApplicationFiled: June 21, 2023Publication date: February 8, 2024Inventors: Guy Sella, Meir Adest, Lior Handelsman, Yoav Galin, Amir Fishelov, Meir Gazit, Ilan Yoscovich, Yaron Binder
