I use this in a remote summer house and have it running at just below max capacity. It is pushing more amps to the batteries then any other controller that I have used. The build quality is great on this. Its a solid unit. I have it running a 12v battery bank from a 48v mixed array (440w array and a 240w array) and get around 50-52amps at peak sun into the batter bank. The arrays and charger are also around 80 feet apart so having a controller that would convert the voltage was critical.
