Review on Efficient Solar Charging With 80A MPPT Charge Controller - Ideal For AGM, Sealed & Lithium Batteries by Bryan Murphy

Notice that the screen locked this morning. I tried resetting the device several times by removing both solar panel power and battery power to no resolution. The safety features of the device stopped working such as if no battery power is present the device does not shut down. If not watched it could start a fire.Also for such an expensive controller it is not up to FCC specifications (United States Federal Communications Commission). It outputs a whole lot noise (RFI) in the VHF bands of the spectrum. I don't know how they can sell the device if it is outputting harmful radio frequency interference. By law devices are not allowed to emit RFI that is harmful or causes noise in any of the radio communications bands.It would seem a lot of people are having issues with this device. Are not able to get easy customer service from the manufacture.
