Characteristics of the Best MPPT Solar Charge Controller in India

A complete solar power system consists of many components, and a solar charge controller is a vital part of it. It is used to modulate the current amperage moving from the solar panels to the batteries. A solar controller is basically a regulator that prevents the batteries from overcharging, which may cause heating and thereby pose a safety risk.

There are broadly two types of solar charge controllers—PWM controllers and MPPT controllers. PWM or Pulse-Width Modulation tend to be smaller and operate on battery voltage, whereas MPPT controllers use newer technology that operates on maximum power voltage. In this article, we will understand everything you need to know about solar controllers, including the top characteristics of the best MPPT solar charge controller in India.

What is an MPPT Solar Charge Controller?

Maximum Power Point Tracker, or MPPT, is basically used to maximize the output of a solar power system. It was first invented by an Australian company in 1985, and this technology is now used in many grid-connected solar inverters and solar charge controllers.

MPPT is an advanced technology that enables solar panels to operate at the maximum power point or, more specifically, the optimum current and voltage for maximum power output. The best MPPT solar charge controller in India can be up to 30% more efficient. Also, MPPT controllers fall on the expensive side among the different types of solar charge controllers.

How Does an MPPT Solar Charge Controller Work?

The working principle of the best solar charge controller is quite simple. Since a varying amount of sunlight falls on the solar panels throughout the day, the panel current and voltage tend to vary. So, with the goal of generating the most power, an MPPT sweeps through the solar panel voltage and finds a sweet spot, or more formally, the best combination of current and voltage, in order to produce maximum power.

This technology has the ability to continuously track and adjust the panel voltage to maximize the power output, irrespective of the time of the day and weather conditions. Now that we know what an MPPT solar charge controller is and how it works, it is time to look at the top characteristics of the best MPPT solar charge controller in India.

Characteristics of an MPPT Solar Charge Controller

Here are some of the key characteristics of the best solar controller:

• The best MPPT solar charge controller in India allows the solar array to be at a higher voltage than the battery bank. This is very useful for areas that receive lesser sunlight or during winter when the sun doesn’t shine for long.
• This technology offers an increased charging efficiency of up to 30% compared to the PWM solar charge controllers.
• The MPPT solar charge controller also provides greater flexibility for the growth of systems, which is quite relevant for commercial establishments.
• They generally come with a longer warranty period compared to other types of solar charge controllers.
• An MPPT solar charge controller is essential for a solar power system to extract optimal power from the solar panels. It makes the panels operate at a voltage close to the maximum power point.
• An MPPT controller reduces the complexity of the system while making it highly efficient.

Difference Between MPPT & PWM Solar Charge Controller

Here is a table to give you a brief idea about the key differences between the PWM and MPPT solar charge controllers:

Parameter	PWM	MPPT
Efficiency	PWM controllers are relatively less efficient. The maximum efficiency can go up to 65%.	MPPT controllers are quite efficient. Their efficiency can go up to 95%.
Size	They are smaller in size.	The MPPT controllers are designed to support big solar panels in an effective manner.
Limitation	They cannot be used with bigger solar panels.	MPPT controllers are recommended with a bigger solar power system due to their high efficiency
Cost	They are less expensive.	They are relatively expensive.
