本发明的较佳实施方式
如图1所示，一种组合式模块化户用储能系统，包括逆变器200、电池箱100和底座300，所述的逆变器200、电池箱100和底座300从上往下依次形成可拆卸连接，还包括呈竖直设置的侧板组件，所述的逆变器200、电池箱100和底座300的两端分别与侧板组件固定连接。
本发明，采用了模块化设计，单模块的设计可进行分包装运输，便于安装、运输及后期扩容；电池箱100与逆变器200层叠安装，省去了分开安装的繁琐，系统连接更加便捷。
电池箱100和与逆变器200可根据系统组合配置，如图3所示，在逆变器200和底座300之间设有若干个电池箱100，若干个电池箱100从上往下依次叠合并形成可拆卸连接，位于最上方的电池箱100顶部与逆变器200底部固定连接，位于最下方的电池箱100底部与底座300顶部固定连接。在实施例中， 可根据应用需求组合配置电池箱100容量与数量以及逆变器200功率大小，虽然图2中示出了3个电池箱100相互叠合，但并不代表只能叠合3个电池箱，也可以是2个，4个或更多个。
在本实施例中，结合图2所示，侧板组件包括左侧板400和右侧板500，所述的左侧板400和右侧板500上分别设有若干沿左侧板400和右侧板500的轴向设置的连接孔，连接孔与逆变器200、电池箱100和底座300的位置对应，锁紧件穿过连接孔后使左侧板400和右侧板500分别与逆变器200、电池箱100和底座300形成固定连接。锁紧件可以是螺丝、螺钉或螺栓等，在逆变器200、电池箱100和底座300的两端设有与连接孔对应的螺孔，用于连接。
再结合图4和图5所示，左侧板400和右侧板500上设有若干加强筋，加强筋也即支撑柱，用于提高左侧板和右侧板的强度，起到抗震效果，加强筋使整个侧板组件强度明显提高，从而使整个系统更加稳固。连接孔设置在加强筋上，左侧板400和右侧板500分别通过连接孔与逆变器200、电池箱100和底座300的两端固定连接。
具体的说，如图4和图5所示，逆变器200、电池箱100和底座300的两端分别设有与左侧板400和右侧板500上的连接孔相配适的逆变器固定孔202、电池箱固定孔103和底座固定孔302。逆变器固定孔202、电池箱固定孔103和底座固定孔302均为螺纹孔，便于采用螺纹件与左侧板和右侧板进行连接。本领域技术人员应当理解，左侧板和右侧板上的连接孔，以及逆变器固定孔202、电池箱固定孔103和底座固定孔302的位置和数量可以根据实际情况进行设置，目的是用于实现连接，连接孔的数量大于逆变器固定孔202、电池箱固定孔103和底座固定孔30的数量，便于后期电池箱的扩容。
底座300底部设有底座安装孔301，底座安装孔301与地面地脚螺栓固定，用于固定整个户用储能系统。底座300顶部设有底座定位销303，电池箱100的底部设有与底座定位销303相配适的电池箱定位孔101，当电池箱100置于底座300上时，底座定位销303插入到电池箱定位孔101中，所述的电池箱100顶部设有电池箱定位销102，逆变器200底部设有与电池箱定位销102相配适的逆变器定位孔201，当逆变器200置于电池箱100上时，电池箱定位销102插入到逆变器定位孔201中。
上述的定位孔与定位销，相互配合，安装方便，使底座300、电池箱100和逆变器200完成层叠安装，安装完成后实现了径向定位，径向位置保持稳固。
优选方案，底座定位销303有两个并位于底座300中心线的两侧，所述的电池箱定位孔101和电池箱定位销102分别有两个且位于电池箱100中心线的两侧，所述的逆变器定位孔201有两个且位于逆变器200中心线的两侧。
更有选的方案，两个底座定位销303沿底座300对角设置，所述的两个电池箱定位孔101和两个电池箱定位销102分别沿电池箱100的对角设置，所述的两个逆变器定位孔201分别沿逆变器200对角设置。对角设置，便于对位固定，方便安装。
申请人发现，设置两个对角的定位孔和定位销，是最佳方式，如设置3个或以上的定位孔和定位销，在加工过程中需要保证非常精确的尺寸，否则安装时会导致定位销和定位孔无法一一对应，无法实现层叠，两个定位孔和定位销的对角设置，既保证了定位的强度和精度，又能方便调整角度进行配适。
如图5和图6所示，电池箱100靠近左侧板400的一端设有若干个电池箱防水连接器104，用于电池箱的正负极连接与控制连接，所述的右侧板500上设有外部接口板501。外部接口板501用于外部进线，可匹配配线保护用软管，位置不限。
逆变器200靠近左侧板400的一端设有若干个逆变器防水连接器203，用于逆变器与电池箱的正负极连接及控制连接。逆变器200靠近右侧板500的一端设有若干个防水接头205，用于光伏直流侧输入、电网侧及负载交流侧输出、外部通信等。逆变器200顶部可拆卸的设有顶盖207，用于客户现场开盖进行系统接线，完成接线后，闭合顶盖。逆变器200的其中一个侧壁上设有指示灯204，另一个侧壁上设有散热器206，用于逆变器的功率器件散热。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
