Solar Charge Controller
A solar charge controller is used to regulate the energy flow from the solar panels to the battery by adjusting the parameters of Intensity (I) and Voltage (V).

MPPT Charge Controllers
The MPPTor ‘Maximum Power Point Tracking‘ controls are much more sophisticated than the PWM controllers and allow the solar panel to run at its maximum power point or, more precisely, at the optimum voltage for maximum power output. Using this smart technology, MPPT Solar Charge Controllers can be up to 30% more effective based on the attached solar panel’s voltage and voltage.
The controller takes in power from solar panels.
The controller regulates the amount of power that goes to the battery.
The controller only allows power to flow from the solar panels to the batteries.
The controller monitors the battery's voltage to prevent overcharging.
