An MPPT controller typically achieves about 20% (but up to 40%) better charging power than a traditional PWM controller. Despite the higher purchase price, it pays for itself quickly. The charging efficiency of the MPPT controller is approx. 95-98%, while the efficiency of the pulse width controller is approx. 50%-60%, due to the rough on-off regulation. The MPPT controller always looks for the intersection of the highest panel voltage and current as the cut-off point and converts the excess voltage into charging current with a chopper.
NOTE! This model exceptionally lacks the charging and consumption current view! The consumption current reading comes through the output port, but usually in cabins and motorhomes the consumption is electrified directly from the battery, so this output port is usually irrelevant.
Charging works normally, but the charging and consumption current values will not appear on the screen.
