Solar Panel Controller that Can Handle Two 190 Watt Solar Panels

Question:

Hello, We already have a 110W solar panel on the roof of our trailer and the solar controller will accept up to 190W. Solar Controller: gp-pwm-10-sq If we add a second 110W panel will we have to swap out the solar controller as well or will is just be limited to 190W? Thanks in advance for considering my question.

The controller you have now can only accept up to 190 watts of power so you will need a new one. We have the Go Power MPPT Solar Charge Controller # GP54FR which can handle the wattage you'll have. This can handle 12V up to 800 watts, 24V up to 1,600 watts, 36V up to 2,400 watts, and 48V up to 3,200 watts.
