Epever's Tracer MPPT Controller is cutting-edge technology with automatic voltage sensing, automatic configuration saving, using 60A on the main panel array to power the main battery pack along with a smaller mixed array panels are used by Epevers 4210 Tracer AN controlled. Connecting two arrays with Epevers Tracer AN Series controllers was a breeze - easy installation with a clear, simple display of system status. I have taken for both remote monitors. Feedback on the Epevers Tracer AN controllers is positive, they indicate reliability and stable operation. I have just purchased a 20A Tracer AN for my hydroponic system which is separate from the main standalone system. I love that I can adapt the controllers to suit different uses around my homestead - the Tracer AN controllers are the same for all models which makes them very easy to use.
