Review on SUNYIMA 60A MPPT Solar Charge Controller - LCD Display, Dual USB, Multiple Load Control Modes - New Mppt Technology, Max Charging Current 60A by Gabriel Tomato

Works, that's all. Not sure what Amazon's policy is for false product advertising, but this is clearly not an MPPT controller! After using it alongside a real MPPT controller and comparing the data, it doesn't come close. Less voltage on panels and less on batteries. I have 8 panels and split them into 4 with this controller and 4 with the slightly more expensive MPPT and was hoping it would be about the same but it wasn't. So I tried to compare it with a cheaper PWM and in fact its specs were almost identical. Just buy a cheaper PWM or spend a little more and get a real MPPT controller.
