Details of MPPT Solar Charge Controller Settings Pakistani Method

There are various types of Solar Charge Controllers and Smart Battery Chargers are available in Pakistani market. Solar battery chargers or charge controllers are efficient devices for standalone small 12-Volt DC Solar Power Systems.

 

There are two main types of Solar charge controllers thar are PWM Solar Controllers and MPPT Solar Charge Controllers.

Solar Charge Controller is such type of device which is designed to charge Battery or batteries from Solar Panels, its main feature is to protect battery from over-charge and over dis-charge, also to provide power to connected load.

To understand the efficiency and working of MPPT controller you have to read the following lines.

PWM solar charge controllers are basic type of controllers which are widely used to handle small battery and small load. Usually used in solar powered streetlights, its charges battery at Day and Power the light at night.

MPPT solar charge controllers can handle large number of loads, this type is usually used small standalone DC Solar systems where it charges battery at day during sunlight and also provide power, at the same time, to connected load such as DC Fans and DC lights in homes and provides backup power at night from battery.

However, PWM controllers can also provide power to the load while charging the battery at day but there are differences between them that are Efficiency, Charging Method, Suitability and Price.

MPPT technology is more advanced and efficient, it adjusts input to harvest maximum power from the solar array, while PWM operates at lower efficiency.

MPPT controllers are up to 30% more efficient. MPPT matches panel resistance to battery resistance, on the other side PWM pulls down panel voltage to match battery voltage.

MPPT controllers are suitable for larger solar systems, while PWM controllers are cost-effective and reliable for smaller systems.

PWM stands for Pulse Width Modulation while MPPT stands for Maximum Power Point Tracking, hope you can now easily understand the differences between PWM and MPPT technology.

In simple words the MPPT controller converts the extra voltages of the connected solar panel to Amperes to increase efficiency on the other side the PWM controllers are low in cost than MPPT.
