本研究整合現有功率優化器設計、最大功率點追蹤法等，開發以並聯架構輸出的分散式獨立型太陽能系統。以使用微控制器PIC32做為運算核心的系統控制器建立與功率優化器的通訊，傳送穩壓指令並接收太陽能板輸出電壓、電流等相關資訊進行最大功率點追蹤。本研究也將電池管理系統整合至系統控制器中，包括兩階段式充電法的充電保護機制與開路電壓法搭配庫倫法的電量估測方法。此外，添加BM77藍牙模組至系統控制器中，配合以UNITY開發之應用介面讓使用者可以使用行動裝置透過藍牙通訊進行發電狀況監控與對控制器內之參數進行設定，達到無線監控的功能。
於測試階段，利用LabVIEW軟體，針對不同溫照度條件進行特性曲線模擬，提供系統控制器進行MPPT，驗證二次式極值演算法程式撰寫的正確性；接著透過太陽能模擬器模擬太陽能板輸出實際電壓電流配合功率優化器進行系統功能測試。
系統實測階段，以不同太陽能板條件進行系統整日發電測試，驗證系統自動開機與關機、MPPT運算與電池管理等系統功能穩定性。加上定時開啟的功率負載進行長時間的系統應用測試，驗證系統長時間運作下的充放電狀況，驗證系統的可靠性。

This paper presents a distributed stand-alone photovoltaic system design utilizing Bluetooth technology for monitoring. The ability to conduct Maximum power point tracking (MPPT) are established for the system. A power optimizer design established previously is used in the system. A new stand-alone PV system controller design using microcontroller (MCU) PIC32 as CPU is built and BM77 is used as Bluetooth interface for the controller. A battery management system including two-stage charging control and battery capacity estimation is also integrated in the controller. A mobile device APP interface software application using Bluetooth communication for monitoring and controlling is developed by UNITY multiplatform game engine.
To test the system, some simulations and field test experiments are conducted. PV characteristic curve with different irradiation is firstly simulated by LabVIEW in order to verify functionality of Quadratic Maximization (Q.M) MPPT program in the controller. By using Solar Array Simulator, the MPPT function with real power input and two-stage charging control are tested. Then, some field test including stability test for system operation for different durations and different load conditions with two PV modules configuration is conduced to verify the system function.
