The MPPT solar controller utilizes maximum power point tracking technology to ensure that the photovoltaic system is charged with maximum current, even if some components fail or the light is relatively dim due to weather.

The maximum power point tracking technology will greatly "increase" the charging current of the solar power system. For example, the PV module has 8 amps flowing into the MPPT solar controller, and the MPPT solar controller may generate 10A current to charge the battery. What needs to be reminded here is that the MPPT solar controller itself does not generate current, and the energy input to the MPPT solar controller is equal to its output energy.
 MPPT is also charged in three stages to ensure battery life. When the voltage of the solar panel is much higher than the battery voltage, we usually recommend using the MPPT controller, which improves the efficiency more. Due to its complex design and high cost, its widespread application is largely limited. Low-power and low-voltage solar photovoltaic panels, most customers still prefer to use PWM controllers, which are economical.
