Abstract: A photovoltaic (PV) system includes module-level power electronic (MLPE) devices that produce energy. The PV system includes a gateway to receive and send data to MLPE devices. The gateway also connects the PV system with a network, such as a local area network, that allows access to the Internet. The gateway provides functionality within the PV system to perform various processes to improve operation of MLPE devices.

Abstract: A photovoltaic system includes groups of solar cells that can be switched in and out of the photovoltaic system. In response to detecting initiation of rapid shutdown, a control circuit controls a switch device to switch out a group of solar cells to lower the output voltage of the photovoltaic system below a safety level. In response to detecting a release trigger that indicates resumption of normal operation, the control circuit controls the switch device to switch back the group of solar cells to restore the output voltage of the photovoltaic system to a normal operating level. Solar cells may be switched out by disconnecting them from the photovoltaic system and switched back by reconnecting them into the photovoltaic system. Solar cells may also be switched out by shorting them out of the photovoltaic system and switched back in by removing the short.

Abstract: A solar device system includes one or more solar devices shingled into an array of solar devices. Each solar device includes one or more current generation cells configured to generate electric current, a plurality of current buses, and a control circuit configured to distribute the generated electric current to the plurality of current buses, and route the generated electric current to an adjacent solar device. Additionally, the solar device system includes an array collector electrically connected to the one or more solar devices, the array collector being configured to collect the generated electrical current from the one or more solar devices and direct the generated electrical current to an inverter or a power grid.

Abstract: Differential power processing (DPP) converters are used within circuit architecture of solar power modules to process the mismatched power between solar elements in a power module. The DPP converters use various topologies to process the mismatched power. These topologies can include a housekeeping power supply where the housekeeping power is coupled to the main bus, or, through various other tapping topologies, including to a subset of PV cell substrings.
