Review on Renogy Rover 60 Amp MPPT Solar Charge Controller: All-in-One Adjustable LCD Display for Gel, Sealed, Flooded, Lithium Batteries by Tyler Suarez

My problem with the charge controller is the voltage measurement. It was about 0.7 volts higher than the measured battery voltage. And the charge controller has Bluetooth connectivity that can't be matched at the famous 80 feet. There is a need to improve the charge controller's communication with something like an Ethernet system. You need to fix the voltage detection in the charge controller.
