Discussion about solar power charger controllers.

Steemian Friends,
Today, I will discuss solar power charge controllers with Steemian friends. In a previous post, I discussed how solar panels generate electricity from the sun. Today, I will discuss devices that deliver the electricity generated from solar panels to batteries or electrical loads.

MPPT Solar Charger Controller

Solar panels generate electricity from sunlight and deliver it to the electrical load via two devices. Solar charger controllers are used to provide DC power. Inverters are used for AC power generation. Today, I will discuss solar charger controllers for a DC power supply. DC solar charger controllers are of two types.

Namely:

• PWM(Pulse Width Modulation)
• MPPT (Maximum Power Point Tracking)

• PWM(Pulse Width Modulation):
  PWM is a DC solar charger controller. It transmits DC power from the solar panel to the battery or load. A PWM solar charger controller is used for low load, low ampere, or small-sized solar panels. Generally, a PWM charger controller is used for a (0-10) ampere load.

• MPPT(Maximum Power Point Tracking):
  The MPPT solar charger controller is more advanced than the PWM charger controller. It provides the maximum power from solar panels by using electronic circuits. The electricity generated from solar panels is more than PWM. Its efficiency is much higher and more sustainable. For electricity generation above 10 amperes, an MPPT solar charger controller is used. It is larger in size than the PWM charger controller. The work of the two charger controllers is almost the same. The main difference between them is the load ampere. If the load current is higher, use MPPT; if it is lower, use PWM.

Function:
DC power is supplied to the battery through a PWM solar charger controller. Excess current or voltage is controlled by the charger controller. Besides, it automatically closes and opens the supply when battery charging is complete. The charger controller detects faults in the solar system through various signals.

I hope my Steemian friends have understood my lesson about solar charger controllers today. In the next post, I will discuss AC solar inverters.
