Solar controller is also known as solar charge and discharge controller. It is used in solar power generation systems to regulate the charging of batteries from photovoltaic panels. And provide automatic control device for the voltage sensitive equipment load control voltage. It regulates and controls the charging and discharging conditions of the battery. And it controls the power output of the solar cell module and the battery to the load according to the power demand of the load. It is the core control part of the whole photovoltaic power supply system.


MPPT solar controller full name maximum power point tracking type solar controller. Multiply the voltage and current of the solar cell to get the power. And then determine whether the solar cell’s output power reaches its maximum.




MPPT solar controller full name maximum power point tracking type solar controller. Multiply the voltage and current of the solar cell to get the power. And then determine whether the solar cell’s output power reaches its maximum.


If the operation is not at the maximum power point, adjust the pulse width, modulate the output duty ratio, change the charging current, and conduct real-time sampling again to determine whether to change the duty ratio. This optimization process ensures that the solar cells are always operating at their maximum power point to make full use of the energy output of the solar array.
