I have one of your watt meter power analyzers wired between solar panel cable close to the controller via anderson plugs. I leave everything connected for days.When there is no sun at night, next morning the meter just has a bar across the top and have had to disengage it from the cable to get it to start reading. Is this the norm or will it restart if there is enough sun light to get it back up.
