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

Publication number: 20240128757Abstract: A method to control storage into and depletion from multiple energy storage devices. The method enables an operative connection between the energy storage devices and respective power converters. The energy storage devices are connectible across respective first terminals of the power converters. At the second terminals of the power converter, a common reference is set which may be a current reference or a voltage reference. An energy storage fraction is determined respectively for the energy storage devices. A voltage conversion ratio is maintained individually based on the energy storage fraction. The energy storage devices are stored individually with multiple variable rates of energy storage through the first terminals. The energy storage is complete for the energy storage devices substantially at a common end time responsive to the common reference.Type: ApplicationFiled: October 17, 2023Publication date: April 18, 2024Inventor: Meir Gazit

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

Patent number: 11888387Abstract: A distributed power system including multiple DC power sources and multiple power modules. The power modules include inputs coupled respectively to the DC power sources and outputs coupled in series to form a serial string. An inverter is coupled to the serial string. The inverter converts power input from the serial string to output power. A signaling mechanism between the inverter and the power module is adapted for controlling operation of the power modules. Also, for a protection method in the distributed power system, 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.Type: GrantFiled: December 5, 2016Date of Patent: January 30, 2024Assignee: Solaredge Technologies Ltd.Inventors: Meir Adest, Guy Sella, Lior Handelsman, Yoav Galin, Amir Fishelov, Meir Gazit, Yaron Binder
