摘要： A method of configuring an installed energy harvesting device to comply with a local grid connection standard is provided. The method identifies a local grid connection standard for an energy harvesting device that has been installed in a physical installation. The method then configures the energy harvesting device to apply the identified grid connection standard. To identify the local gird connection standard, the method determines a physical location for the installation of the energy harvesting device. The method then identifies the local grid connection standard based on the determined physical location.

摘要： We describe a photovoltaic (PV) panel system comprising a PV panel with multiple sub-strings of connected solar cells in combination with a power conditioning unit (microinverter). The power conditioning unit comprises a set of input power converters, one connected to each sub-string, and a common output power conversion stage, to provide power to an ac mains power supply output. Integration of the micro-inverter into the solar PV module in this way provides many advantages, including greater efficiency and reliability. Additionally, embodiments of the invention avoid the need for bypass diodes, a component with a high failure rate in PV panels, providing lower power loss and higher reliability.
