This is NOT an MPPT controller as described, it is a PWM controller. I tested it and it should maintain the PV panel volts at its MPPT value of 30 to 38 volts but it reduced it to just over the battery voltage of 14 volts.

Eugene atrue MPPT would still output 14 volts but the Amps will go higher than rated on panel. (say panel can push 5amps @ 19v for a 100w. it will go 14.4v but @ 6.5amps) vs PWM will go 14.4 * 5amps at max which is a mere 72watts out of a 100watt solar panel.
