  • Patent number: 10847972
    Abstract: In one embodiment, a photovoltaic (PV) power generation system includes a plurality of PV arrays coupled to an automatic switchbox that connects the one or more PV arrays in series or in parallel with each other based at least in part on output voltage of the switchbox. In this embodiment, the automatic switchbox monitors the output voltage and ensures that the output voltage is within a predetermined operational range. If the output voltage exceeds a first predetermined voltage, then the array switchbox electrically couples one or more PV arrays in parallel with each other, which reduces the output voltage within the predetermined operational range. If the output voltage falls below a second predetermined voltage, the switchbox connects one or more PV arrays in series with each other, which increases the output voltage to within the predetermined range.

  • Patent number: 10326267
    Abstract: Provided herein are improved apparatuses and methods for protecting polarity sensitive loads in DC power circuits that include a power source, a relay coupled to the power source, and a polarity sensitive load coupled to the relay. A diode can be coupled between the power source and the relay. When the power source provides a DC voltage of a desired polarity, the diode can block a current from flowing to a coil of the relay. Consequently, the relay can provide a current path to the polarity sensitive load. When the power source provides a DC voltage of an incorrect or reverse polarity, the diode can allow a current to flow to the coil of the relay. In turn, the coil of the relay can be energized, causing the relay to disrupt the current path provided to the load, thereby protecting the polarity sensitive load from the reverse polarity condition.

A shutdown implementation module is coupled between an energy panel arrangement and a power converter that converts DC power from the energy panel arrangement to AC power for an AC power grid. Responsive to identifying a power shutdown condition, the shutdown implementation module shuts down output power from the energy panel arrangement to the power converter.

The shutdown implementation module may be located within a threshold distance from the energy panel arrangement (e.g., within about 10 feet) so that the output power may be shut off within a threshold timespan (e.g., within about 10 seconds).

    Abstract: Systems, methods, and devices relating to the control of power conditioning systems. For a micro-inverter, a controller block controls the DC/DC converter while a separate controller block controls the DC/AC inverter. A dynamic maximum efficiency tracker (DMET) control block receives state variable outputs from the converter and the inverter. The control block then perturbs specific control input parameters for the converter and the inverter and determines the effect of the perturbation on the converter and inverter efficiencies and on micro-inverter efficiency as a whole. If the efficiency decreases, then the direction of the perturbation is reversed. Other system control tasks, such as maximum power point tracking and DC-bus voltage regulation can be performed concurrently by adjusting other control input parameters.

The operation of the system may yield direct current or with the integration of bidirectional micro-inverters create distributed alternating current generation enhanced with energy storage and control two way energy flows between the solar system and the grid.

  • Patent number: 9876360
    Abstract: An improved micro-inverter apparatus is disclosed for intelligently controlling energy harvest from photovoltaic solar panels based on one or more adjustable, user-defined variables. The improved micro-inverter apparatus may include a microcontroller configured to monitor the operating temperature of its micro-inverter and control the power harvested from associated solar panels in order to ensure the operating temperature of the micro-inverter does not approach a level that would damage the micro-inverter's circuitry or other components. Similarly, the micro-inverter apparatuses' microcontroller may be configured to monitor the total harmonic distortion of the micro-inverter's AC power output and control the power harvested from associated solar panels in order to ensure the total harmonic distortion of the AC power output does not exceed a threshold level.

  • Patent number: 9825584
    Abstract: Apparatus and techniques for controlling measurement of an electrical parameter of an energy source can be used to obtain information for use in enhancing a power transfer efficiency between the energy source and a load. For example, during a first measurement cycle, information indicative of the electrical parameter of the energy source can be obtained using a measurement circuit during a first sampling duration in which the load is decoupled from the energy source. The information indicative of the obtained electrical parameter can be compared to a threshold. In response to the comparing, a different second sampling duration can be determined for use in obtaining information indicative of the electrical parameter during a subsequent measurement cycle. The information indicative of the electrical parameter of the energy source includes information for use in enhancing the power transfer efficiency between the energy source and the load.

    Abstract: An illuminated ornament having an electronics assembly including a battery holder, a cap, a light emitting source and a control circuit is inserted through a hole axially into the ornament enclosure thereby locating the light source at a distance from the enclosure wall. The enclosure wall allow light to travel therethrough. A diffusing and reflecting cap which is preferably conical shaped converging towards a disk shaped end wall surrounds the light source and both allows light to travel therethrough and reflects light behind the light source to the enclosure wall. The battery holder is permanently attached to the assembly cap and the electronics assembly is removable from the enclosure in one piece. The assembly cap closes the hole. The differential pressure between the inside and outside of the enclosure is relieved preventing air and water entry through the assembly cap to enclosure interface.
