OLARITY

 

 
It is important to understand that the polarity of the PT (12Vac wall transformer) will change the polarity of any channel 
that is “net metering” enabled (highlighted in green). For instance, if the wall transformer (PT)  is unplugged turned 180 
degrees and re-plugged such that the 120V receptacle blades are reversed, all net metering enabled channel polarities 
will change. See
