The working principle of a 100 amp MPPT (maximum power point tracking) solar charge controller is based on the fact that the current-voltage (I-V) characteristics of a photovoltaic (PV) solar panel array are non-linear, meaning that the amount of power that can be extracted from the array varies with the voltage and current.
The MPPT solar charge controller continuously tracks the maximum power point of the PV solar panel array and adjusts the voltage and current of the charging process to extract the maximum amount of power possible.
To do this, the controller uses a control algorithm that compares the current and voltage of the PV solar panel array to the current and voltage of the battery or battery bank being charged. Based on this comparison, the controller adjusts the charging process to ensure that the maximum power is being transferred from the PV solar panel array to the battery or battery bank.
In addition to optimizing the charging process, the 100 amp MPPT solar charge controller also provides protection for the battery or battery bank by preventing overcharging and over-discharging, as well as controlling the load connected to the battery or battery bank.
Overall, the MPPT solar charge controller helps to improve the efficiency of the charging process and extend the lifespan of the battery or battery bank.
