摘要： Methods for measuring insulation resistance in a photovoltaic (PV) array may include partitioning the PV array into groups of PV panels, isolating a group of PV panels selected for an insulation resistance measurement from other groups of panels by setting bypass selectors on each PV panel in the PV array, and making an insulation resistance measurement for the selected group. If a measured value of insulation resistance for a selected group corresponds to an insulation problem in a PV array component, a separate measurement of insulation resistance may be made for each PV panel in the selected group. Insulation resistance measurements may be made accurately and rapidly for large PV arrays without disconnecting and reconnecting cables between panels. Measurements may be made at frequent, regular intervals to permit changes in insulation resistance to be detected before damage from dielectric breakdown occurs.
摘要翻译：用于测量光伏（PV）阵列中的绝缘电阻的方法可以包括将光伏阵列分隔成多组光伏面板，通过在每个光伏面板上设置旁路选择器来将为绝缘电阻测量而选择的一组光伏面板与其他面板组隔离光伏阵列，并为选定的组进行绝缘电阻测量。如果选定组的绝缘电阻的测量值对应于PV阵列组件中的绝缘问题，则可以对所选组中的每个PV面板进行绝缘电阻的单独测量。对于大型光伏阵列，绝缘电阻测量可以准确而迅速地进行，而无需断开和重新连接面板之间的电缆。可以定期进行频繁测量，以确保绝缘电阻发生变化之前检测到绝缘电阻的变化。

摘要： A photovoltaic (PV) panel monitoring apparatus includes a monitoring module for measuring parameter values related to PV panel output, comparing measured values against minimum and maximum values saved in the monitoring module, and outputting an alarm signal when a measured value is outside a range defined by the minimum and maximum values. An alarm signal causes a visual indicator to activate and an audible indicator to sound, thereby assisting maintenance personnel in locating a PV panel with an out-of-range parameter value. The monitoring module further includes a PV panel identification memory for saving an identification code for each PV panel in a PV array. The identification code is transmitted with time, date, and parameter data when the monitoring module detects an out-of-range parameter value. Data may optionally be transmitted from the monitoring module through a communications input/output port or through a wireless transmitter to an external monitoring and control system.

摘要： A system for maximizing power output from a photovoltaic array includes a configurable photovoltaic panel having a series-parallel selector and a bypass selector electrically controlled by a node controller. Some embodiments further include a plurality of configurable photovoltaic modules. A configurable photovoltaic panel may selectively be electrically connected to other configurable photovoltaic panels in a series circuit, a parallel circuit, or a combination of series and parallel circuits according to switching states set by the node controller for the bypass selector and series-parallel selector. A number of configurable photovoltaic panels connected in series and a number connected in parallel may optionally be selected in response to a change in an output voltage from a photovoltaic array, for example a voltage change resulting from a change in illumination, thereby causing the output voltage from the photovoltaic array to be greater than or equal to a minimum input voltage for an inverter.

摘要： A method for controlling output from a photovoltaic array comprises changing electrical connections between photovoltaic panels in the array in response to changes in parameters related to a selected power transfer objective. Examples of power transfer objectives include matching array impedance to changes in electrical load impedance, outputting power at a maximum power point value, and maintaining array output voltage within the input voltage range of an inverter during changes in temperature, illumination, or other parameters affecting photovoltaic panel output. Photovoltaic panels adapted for reconfigurable electrical connections to other photovoltaic panels, referred to as intelligent nodes, are electrically interconnected according to the disclosed method in combinations of serial and parallel circuits selected according to measured and calculated values of parameters related to the selected power transfer objective. A photovoltaic array operating in accord with the disclosed method may be rapidly reconfigured to adapt to changes in measured parameters or changes from one power transfer objective to another.
