 本发明的最佳实施方式
为便于说明本实用新型技术方案的特征及优点，以下结合具体实施例进行说明。实施例中各种不同物件是按适于说明的比例、尺寸、变形量或位移量而描绘，而非按实际元件的比例予以绘制。且以下的说明中，相同的元件是以相同的编号来表示。
如图1所示，本实用新型为一种整合再生能源的屋内节能供电装置，其主要包括：
一第一供电端10，其为一直流供电源，例如太阳能电池、风力发电机、水力发电机或燃料电池；
一第二供电端20，其为一交流供电源，例如市用电电源；
一控制模组30，其分别与该第一供电端10及第二供电端20相连接，并可检测该第一供电端10及第二供电端20的供电状况，以切换供电来源；
一稳压整流模组40，其与该控制模组30相连接，并借助该控制模组30控制切换稳压整流模组40与第一供电端10及第二供电端20的电性耦合状态；其中，该稳压整流模组40包含至少一稳压单元41、一整流单元42及一直流变频单元43；

结合上述结构，以下针对本实用新型的工作及原理作详细说明，而为便于解说，以下以太阳能电池为实施例叙述，非仅限于实施于太阳能电池：
如图2所示，当控制模组30检测到连接于第一供电端10的太阳能电池产生供电时，将稳压整流模组40切换至与第一供电端10电性连接，使第一供电端10所提供的电能经过稳压、整流及变频等工作后，将电能储存于该储能模组50内，以便供负载端需用电时使用，如图3所示，可通过该第一供电电路61供给电能，以达到有效利用太阳能发电和节能的目的。
再请参阅图4所示，当第一供电端10的太阳能电池因为天气等因素导致供电中断或不足以有效利用时，该控制模组30可将稳压整流模组40切换至与第二供电端20电性连接，使第二供电端20所提供的电能经过稳压、整流及变频等工作后，将电能储存于该储能模组50内，可确保天气状况长时间不佳时仍能保有充足储能，确实防止太阳能电池因天气等因素无法对储能模组50充电，而产生在需用电时储能用尽的窘况。
且该控制模组30更具有检测储能模组50的储能状态功能，以于该储能模组50储能饱和时，主动切断第一供电端10与第二供电端20的导通，防止因过度充电而导致该储能模组50损坏。
再者，如图5所示，该电能输出端60与储能模组50更可设有一第二供电电路62，以利用该第二供电电路62直接将第一供电端或第二供电端20所提供的电能，经过稳压、整流及变频等工作后，直接提供给该电能输出端60的负载端使用，如图6示，以于储能模组50储能不足或需大电流用电时，提供辅助供电之用。其中，本实用新型也可借助该控制模组30控制该第二供电电路62的导通或断路，以主动调整本实用新型的供电方式与状态。
本实用新型的节能供电装置可配置于建筑物的配电箱处，借助其将太阳能发电装置与市用供电端相结合，以达到结合输入再生能源发电及市用电的目的，并提供给原有的电器等用品使用，其本身结构简单、建构成本低廉，且所占空间不大、安装及使用方式简单容易，相当适合一般社会大众使用，可确实、有效地利用再生能源达到节能省电的目的。
虽然本实用新型是以上述最佳实施例作说明，但精于本领域技术者能在不脱离本发明精神与范畴下作各种不同形式的改变。以上所举实施例仅用以说明本实用新型而已，非用以限制本实用新型的保护范围。举凡不违本发明精神所从事的各种修改或变化，均属本实用新型保护范围内。
