Publication number: 20240128926Abstract: A method for testing a photovoltaic panel connected to an electronic module. The electronic module includes an input attached to the photovoltaic panel and a power output. The method activates a bypass to the electronic module. The bypass provides a low impedance path between the input and the output of the electronic module. A current is injected into the electronic module thereby compensating for the presence of the electronic module during the testing. The current may be previously determined by measuring a circuit parameter of the electronic module. The circuit parameter may be impedance, inductance, resistance or capacitance.Type: ApplicationFiled: December 19, 2023Publication date: April 18, 2024Inventors: Meir Adest, Guy Sella, Lior Handelsman, Yoav Galin, Amir Fishelov, Meir Gazit, Tzachi Glovinsky, Yaron Binder

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

Publication number: 20230367354Abstract: A method for maintaining reliability of a distributed power system including a power converter having input terminals and output terminals. Input power is received at the input terminals. The input power is converted to an output power at the output terminals. A temperature is measured in or in the environment of the power converter. The power conversion of the input power to the output power may be controlled to maximize the input power by setting at the input terminals the input voltage or the input current according to predetermined criteria. One of the predetermined criteria is configured to reduce the input power based on the temperature signal responsive to the temperature. The adjustment of input power reduces the input voltage and/or input current thereby lowering the temperature of the power converter.Type: ApplicationFiled: April 17, 2023Publication date: November 16, 2023Inventors: Meir Adest, Lior Handelsman, Yoav Galin, Amir Fishelov, Guy Sella, Yaron Binder
