    • A maximum power level sensor and method for reliably providing instantaneous estimates of maximum power level for a photovoltaic system including one or more photovoltaic cells under prevailing conditions of irradiance, array temperature and spectrum of sunlight. The maximum power level sensor produces a reference voltage signal which is proportional to the maximum power level of the photovoltaic system. The maximum power level sensor comprises a reference circuit including at least one reference photovoltaic cell and a thermistor network in parallel with the reference cell. The thermistor network comprises at least one negative temperature coefficient thermistor, at least one resistor in parallel with the thermistor, and at least one resistor in series with the thermistor and the parallel resistor. The thermistor is positioned in or on the photovoltaic array. The reference cell is preferably constructed of materials which are similar to those of the photovoltaic cells in the photovoltaic system.

    • A system for combining multiple direct current power sources is provided. The system is operable to combine multiple feeds from an array of power generating elements, such as solar panel arrays and combine the feeds into a single voltage output. The system includes a current monitoring assembly operable to monitor the current from each input to evaluate whether there is a malfunction or other problem associated with a particular output. The system also includes a noise detection assembly for monitoring the current to evaluate whether there is a malfunction or other problem. An alarm or other signal can be provided to inform the operator of which power generating element in the array need to be analyzed in response to the output from the current monitoring assembly and the noise detection assembly.
    • 提供了一种用于组合多个直流电源的系统。 该系统可操作用于组合来自发电元件阵列的多个馈电,例如太阳能电池板阵列,并将馈电组合成单个电压输出。 该系统包括电流监测组件,该电流监测组件可操作以监测来自每个输入的电流以评估是否存在故障或与特定输出相关的其他问题。 该系统还包括一个噪声检测组件,用于监测电流以评估是否有故障或其他问题。 可以提供警报或其他信号以通知操作员响应于来自电流监测组件和噪声检测组件的输出而需要分析阵列中的哪个发电元件。
