Are MPPT solar charge controllers Worth It? All things considered, the MPPT solar charge controllers is much better than the PWM solar controller and is well worth buying. Because the MPPT solar charge controllers can capture 25% more power, this is a very cost-effective option.
Why can MPPT solar charge controllers generate 25% more electricity?
From the figure below, we can know that the working voltage of the solar panel is relatively high. When charging the battery through the PWM solar controller, the current does not change, but when charging the battery through the MPPT solar charge controller, the current increases. This is the source of 25% more electricity.
The extra 25% of the power comes from the solar panel, but the PWM solar controller is replaced by the MPPT solar charge controllers, which increases the power by 25%, so the MPPT solar controllers is worthy of our choice.
Another advantage of the MPPT solar charge controller is that it has high voltage input. For example, to charge a 48V battery, the input voltage of the MPPT solar controllers can reach 150V, while the PWM controller is only 72V. The advantage brought by high voltage is low light performance. Well, that means more power is generated on cloudy days.
