  • Publication number: 20200036326
    Abstract: A modular photovoltaic (PV) system can include a PV cell, a frame coupled to the PV cell, and a converter. The frame is configured to support a plurality of pairs of externally accessible connectors, each pair having a positive voltage connector and a negative voltage connector, the positive voltage connector of each pair of the plurality electrically connected to each other and the negative voltage connector of each pair of the plurality electrically connected to each other. The converter is configured to receive voltage from the PV cell and change the voltage for output at one or more pairs of the externally accessible connectors. The converter may include Maximum Power Point Tracking services to manage the power output from the PV cell. Multiple PV systems may be connected to each other in coplanar and non-coplanar relationships. In some embodiments, the frames have triangular, rectangular, or other polygonal shapes.

  • Patent number: 10447043
    Abstract: A photovoltaic (PV) system includes a system control module that determines the presence of a microinverter chain termination end cap. The end cap includes an embedded circuit. The embedded circuit includes components having resistive, reactive, or impedance values. A signal source provides a signal through the microinverter chain. A parameter for a sensed signal detected by the system control module is used to determine the presence of the end cap using a change between the parameter for the sense signal and a reference parameter.

  • Patent number: 10404190
    Abstract: Technologies for communicating information from an inverter configured for the conversion of direct current (DC) power generated from an alternative source to alternating current (AC) power are disclosed. The technologies include determining information to be transmitted from the inverter over a power line cable connected to the inverter and controlling the operation of an output converter of the inverter as a function of the information to be transmitted to cause the output converter to generate an output waveform having the information modulated thereon.

  • Patent number: 10205417
    Abstract: An electric system includes a local power controller and solar panel system that includes a plurality of solar modules on one or more branch circuits. A method for commissioning the electric system includes an installer using a commissioning device to send and receive information from a remote system and the local power controller performing an automatic self-test of the electric system. The results of the self-test may be packaged with photographs and measurements of the electric system and sent to a remote system where an inspector can inspect the electric system remotely. After receiving approval by the inspector, the local power controller may automatically activate each branch circuit of the electric system and thus enabling the electric system to generate electricity.

  • Patent number: 10126131
    Abstract: Location functionality to determine the geospatial location of a PV module is described. This functionality may be performed at the PV module site itself as well as remote from the PV module site. The location functionality may involve the analysis of data collected from the location of the PV module or modules being analyzed as well as data from locations of other PV modules, which are not being analyzed. This data, from other PV modules may be gathered, recorded, and used as a benchmark, or for some other purpose in embodiments.
