What is the MPPT Solar Charge Controller?

With the growing need for renewable sources of energy, solar power systems have gained popularity among electricity users worldwide. The solar power supply not only caters to power needs but also nurtures an eco-friendly mode of electricity production.

Solar power systems have become a staple in most geographical regions where grid power is inaccessible, or people are aware of deteriorating environmental health. However, a solar power system is incomplete without MPPT technology.

The MPPT technology ensures that the maximum amount of captured solar energy is utilized by the solar power stations. You will find a spectrum of MPPT solar charge controllers in the market that function to maintain maximum power output in the solar power system.

Without an MPPT solar charge controller, the solar power station may face some malfunctions. Thus, you must look for a good quality MPPT controller or a solar power station, which can be found at EU.Oukitel.

What is an MPPT Solar Charge Controller?  

The Maximum Power Point Tracking solar charge controller actually converts DC to DC and makes sure that the maximum potential of solar panels is utilized to supply a household. We all know weather conditions fluctuate within weeks or even days.

That is why the solar power supply systems are loaded with MPPT solar charge controller that ensures maximum flow of electricity from solar panels to the batteries. For instance, while power output at sunny days is at its peak, there can be days when the clouds block the sunshine.

On days like these, the solar panels may absorb less sunlight, but the MPPT solar charge controller will push your solar generator kit and keep it going at its maximum pace. It persistently monitors the power output of solar panels and identifies the maximum power point.

Once the controller identifies the maximum power point, it then adjusts the voltage coming from solar panels to match the optimum voltage level needed by the battery. Resultantly, it ensures that the maximum power supply is delivered to the home.

On the other hand, the conventional generator for apartments simply cuts off the voltage to match the power supply needs of the battery. However, as more and more people are relying on solar power supply, the manufacturers are producing the best indoor generator that come with MPPT solar charge controller.

Not only is there a shift in manufacturing, but the market demand has also been revolutionized. Thus, people are also looking for solar power generators that come with MPPT controllers because of their functionality.

How Does MPPT Work?

Before we understand the functioning of MPPT solar charge controllers, let us find out how power, voltage, and current are interconnected. For that, we will have to revise a bit of our physics lesson.

Remember Ohm’s Law, which states power is directly proportional to voltage when current is constant and vice versa. The MPPT controller is an application of this law, and it manages voltage and current in a way that results in maximum output.

Let’s define power, voltage, and current:

• Voltage: It is a pressure between the two nodes of a circuit that induces the flow of charge through the circuit
• Current: It is the flow of charges through the circuit
• Power: It is the measure of energy produced or consumed

Here is the Ohm’s Law:

P = V x I

To put it simply, the power increases when there is a rise in voltage and the current is constant. Likewise, the power also increases with an increase in current when the voltage is not fluctuating.

There can be days with scorching heat when the electricity production by the solar panels reach its peak, On the other hand, there can be times when the sky is cloudy and there is little sunshine for your solar panels to convert it into electric energy.

MPPT continuously tracks down these fluctuations and adjust the voltage and current so that, the power is maximum possible power is generated and stored in the battery of a portable power station or any power station.

Brands in solar power supply industry have taken a step further in terms of technology and are producing portable generators for home backup that come with MPPT installed in them. Oukitell is among the leading names that offer high quality portable solar power stations with in-built MPPT charger.

Benefits of Using MPPT Solar Charge Controllers

MPPT solar charge controllers are a revolutionary invention in the solar power supply domain. It has made it possible for portable solar power stations to ensure stable and utmost output despite the disruptive external factors.

Here is a list of benefits that the MPPT solar charge controllers offer to its users:

• Amplified Power Harvesting: When MPPT is at work, there is no way the solar power stations are not working at their utmost potential. It pulls out all the stops to ensure maximum power output.
• Improved Battery Efficiency:Once the MPPT has made sure that the solar power station is working at its maximum potential, the battery is positively impacted. It makes sure that the battery is charged faster and more efficiently even when the sunlight is blurred.
• Better Performance Despite Fluctuations: No matter how frequent are the weather fluctuations, the MPPT makes sure that the portable solar power stations are functioning properly.
• Increased Power Utility:  The MPPT controller reduces energy wastage and enables maximum utilization of solar energy.
• Long Battery Life:  It adjusts the voltage and current so that the battery gets an optimum level of electric energy. Also, the MPPT controller keeps a stable power flow, which protects the battery from overcharging or undercharging. As a result, the battery lasts longer than you expect.

Now that you know there is a spectrum of benefits that the MPPT offers, you might be on the lookout for the best portable solar power station that comes with an in-built MPPT.  Oukitel solar generators are quite famous among people who rely on solar power supply.

The Oukitel power station comes with an in-built MPPT that ensures efficiency and maximum power output. It will safeguard your battery’s health and will help increase its lifespan.

MPPT vs. PWM Controllers

The Pulse Width Modulation controller works as a switch between the solar panels and the batteries. It turns on when the solar power station is in bulk charger mode and switches off when it is not.

Both the MPPT controller and the PWM controller are poles apart and have multiple key differences. MPPT is used for more complexed and higher powered solar power stations. Furthermore, it is also effective in dealing with the fluctuating weather conditions. On the other hand, PWM has no such functions.

Here is the comparison between the two:

MPPT	PWM
It boosts efficiency by adjusting current and voltage to get maximum output from the solar panels. It increases the efficiency by 30%	It reduces the voltage as the battery charges. PWM can only reduce the voltage, but it cannot improve the efficiency even when weather conditions fluctuate.
MPPT controllers are expensive compared to the PWM because these deploy advanced technology.	PWM comes with a basic design and hence is cheaper than the MPPT controllers.
MPPT controllers can handle high-voltage solar panels and can better utilize excessive current.	PWM works only when the battery voltage and the panel voltage are in alignment.

 

How to Choose the Right MPPT Solar Charge Controller  

While you go out shopping for an MPPT solar charge controller, there are multiple factors that you must look into. For instance, the MPPT solar charge controller should be able to sustain the need for a portable solar power station at your home.

For that purpose, you must look into the system size, voltage range, and configuration of the solar panels. Here are the factors to look into when you go shopping for an MPPT solar charge controller:

• System Size:  You should know the size of your solar power supply,including the number of solar panels, the capacity of the battery, etc. The bigger the size of your solar power station, the more powerful MPPT you will need.
• Voltage Capacity: One should choose an MPPT controller that falls in the maximum voltage range of the solar panels at your home.
• Efficiency: Make sure that the efficiency of the MPPT controller is up to 95% and not less than that.

However, if you are looking for the right MPPT controller for your house, you can rely on the OUKITEL BP2000 Solar Generator 2200W. This solar generator kit comes with the following products:
