A solar charge controller is essentially a solar battery charger wired between the solar panel and battery. There’re two main types of solar charge controllers – PWM (pulse width modulation) and MPPT (maximum power point tracking) with the latter being the primary focus of this post. MPPT Solar Charge Controllers?
CN3791 MPPT Solar Charge Controller Module! The CN3791 MPPT solar charge controller module uses the CN3791 IC which’s a pulse width modulated switch-mode lithium-ion battery charge controller that can be powered by a photovoltaic cell with maximum power point tracking function.
Using the MPPT algorithm, an MPPT solar charger controller can quickly and accurately track the ideal maximum power point (MPP) of a photovoltaic array to obtain the maximum solar energy. This significantly improves the solar system efficiency.
The microcontroller used is in this controller is Arduino Nano. This design is suitable for a 50W solar panel to charge a commonly used 12V lead-acid battery. You can also use other Arduino board like Pro Mini,Micro and UNO. Nowadays the most advance solar charge controller available in the market is Maximum Power Point Tracking (MPPT).
So the Solar panel is now behaving like a 66-watt panel. This equates to a loss of 100W-66.6W = 34W ( 33.4%). This is the reason for using an MPPT charge controller instead of a standard charge controller like PWM. The MPPT controller is consists of a DC-DC converter where the duty cycle is varied to track the Maximum Power Point.
PWM type is an advanced version of an on/off type solar charge controller. A PWM signal is used to control the switching rather than direct on/off. This type of charge controller is a little better than the on/off type charge controller but still can not use the maximum generated power.
