How to choose a good MPPT solar charger controller?

The MPPT solar controller is more complicated, and the cost is also higher. The price is usually several times - ten times that of the PWM solar controller.The MPPT controller can detect the power generation voltage of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with the maximum power output. The MPPT controller also supports connecting more solar panels in series (high dropout), which is also a big advantage.In this case, the cross-sectional area of the connecting cable can be greatly reduced, resulting in a corresponding reduction in the overall cost of the system.

2) The MPPT controller will ensure that the solar panel is always in the best operating condition. In some cases, such as when the weather is cold, the charging efficiency provided by the MPPT method is 30% higher than that of the PWM method (high charging efficiency).

3) MPPT controller is a better choice for large systems, its higher efficiency means good economic benefits. In addition, the MPPT controller allows users to obtain maximum power from the solar panel system, which is a clear advantage in situations where there is additional power demand and limited space prevents the expansion of the solar panel system.
