The controller works as described and does its job quite well. My solar energy collection system consists of 4 solar panels with a total output of 550 watts at 12 volts, an EPEVER MPPT solar charge controller. designed for 60 amps, 3 batteries of 100 Ah each and 1 inverter with an output of 4000 W from 12 to 115 volts. I have a problem with my MT50 Remote Monitor. The soft keys often caught in the surrounding plastic and had to be re-centered with a fingernail. This resulted in the button being pressed multiple times, bypassing the function it was originally stuck in. After contacting the manufacturer, a new MT50 replacement device was immediately sent free of charge. The new device works perfectly! Overall, the support from the manufacturer was timely and excellent!
