What separates ours to the cheaper ones you see?  They do not come with  the plug and play connectors.  They just have power and ground wires coming out of it which makes it more complicated to use.  With the connectors you simply run it inline with your solar panels to help diagnose issues by plugging it in.  No cutting connectors off and monkeying around.
