The energy storage side and the photovoltaic side are easily distinguishable. 
(1) Color distinction: The color of the connector body at both the photovoltaic panel end and the wire end is gray; both the connector at the energy storage panel end and the wire end are blue; the connection scenario of the connector can be distinguished from the appearance. 
(2) Foolproof design: The connectors in the two scenarios have a foolproof design at the insertion point, and the gray and blue connectors cannot be plugged together.
