  • Serially Connected Inverters
    Publication number: 20220077757
    Abstract: A photovoltaic power generation system, having a photovoltaic panel, which has a direct current (DC) output and a micro-inverter with input terminals and output terminals. The input terminals are adapted for connection to the DC output. The micro-inverter is configured for converting an input DC power received at the input terminals to an output alternating current (AC) power at the output terminals. A bypass current path between the output terminals may be adapted for passing current produced externally to the micro-inverter. The micro-inverter is configured to output an alternating current voltage significantly less than a grid voltage.

  • Testing of a photovoltaic panel
    Patent number: 11264947
    Abstract: 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.
