Best MPPT Charge Controller Review – Buying Considerations

Today you can find a large number of load controllers that are available on the market. However, there are some subtle aspects to consider that will help you make a better decision.

It is a set of features that only experts can handle perfectly. So, here we save you the task of researching for hours what the following aspects are all about.

Maximum Input Voltage

One of the well-known myths is that a 12-volt battery bank can be compatible with a 12-volt panel. However, we can mention that this is not entirely true. For that, it is necessary to take into account that energy can vary depending on how it is generated.

In the case of solar energy, then the intensity is not always the same all the time. It is quite common since the sun is not the same all day long. So, this mostly affects the vast majority of panels. Each of these panels will not work at the nominal voltage, due to this variation in energy intensity.

On the other hand, a very common mistake is made by some dealers and homeowners. Some of them may want to create a grid connection system by connecting several panels. Therefore, the controller will need an even higher maximum input voltage.

Only in this way is it possible to compensate for all the additional power needed. The maximum input voltage, the more convenient the load controller will be. In this way, it will be much easier to take into account the different energy variations.

Battery Voltage

The important thing here is that you will be able to find in most of the options, a range between 12 and 48 V DC. However, depending on the batteries or devices you need to work with, then you may need between 60V or 72V. A standard level is usually around 12 VDC. 

Of course, for some people, this is not enough because they are whole homes or very large composite systems. So, in this case, of course, a much higher voltage capacity will be needed.

So, the battery voltage must be exactly adapted to all your needs. This way, you might find an option with a standard voltage or a higher level.

Maximum Output Current

In particular, this aspect indicates the number of devices you will be able to power from the size and type of the battery bank. Exactly the number of amps will be used to charge certain devices. Therefore, it is necessary to analyze the range of amperes that one of the options we have listed can provide.

This will give you much better performance with the 80-amp chargers. Conversely, you can also find more affordable options that offer between 20 and 30 amps. Here you can analyze the number of devices you need to power day after day.

In the same way, you will be able to avoid buying a unit that is insufficient for you.

Additional Features

In these times, you will be able to find a lot of really useful additional features. Each of them can provide you with some advantages for the personalization of your home systems. So, this will be useful, especially when you have batteries and solar panels.

In particular, the best additional features are based on the security you get. So, since you are working with electricity and solar energy, some drawbacks might occur. So, the following features will keep you away from these hazards.

Having a data logger or LED display can increase the functionality of a charge controller. Also, two other useful features are the remote-control management system, along with other safety functions.

Therefore, avoiding electric arcs, reverse polarity, short circuits, overload, or over voltage will be very useful. In this way, you will avoid spending extra money on various repairs.

Along with this, you will also have the ability to find the unit that best suits your needs.

Best MPPT Controller – Must Known Q&A

MPPT ControllerQ. 1: Are MPPT controllers worth it?

Ans: In simple words, we can mention that a load controller is worthwhile, as it can provide a set of excellent benefits. On the one hand, you will have an extra percentage of energy that can benefit a large home system.

Also, the best units can offer certain useful protections. Some of these are protection against short circuits, overvoltages, or reverse polarity. On the other hand, it may be that the voltage of the array bank does not match the array and its voltage itself.

To solve this incompatibility, you can use an MPPT charge controller. This will allow your home system to operate and provide better results. 

Q. 2: Which is better PWM or MPPT?

Ans: Between these two possibilities, the MPPT charge controller is by far the most convenient option overall. This does not include mechanical connections that can be damaged. While the PWM option offers more complexity most people choose the MPPT.

First of all, in several different areas, you will have certain considerable advantages. Each of these options allows you to convert excess voltage to a certain number of amps. This can be very useful for many homeowners, but also some merchants.  

Q. 3: How do MPPT charge controllers work?

Ans: In principle, this charge controller needs to verify the output of the PV module. In the same way, it also compares this with the battery voltage. Therefore, the charge controller can find the optimum power.

This optimum power will then allow a certain charge to be produced for the battery. This charge in turn becomes the optimal voltage to achieve the maximum current.

On the other hand, when this unit is connected to the battery, it will be able to supply power to a DC load.

Q. 4: What size MPPT charge controller do I need?

Ans: Today, you can find different charge controllers, and of course, different capacities. So, among the common classifications, it is possible to find charge controllers of 48 volts, 24 volts, and 12 volts. You should choose the one that best suits your needs.

On the other hand, the amperage can be rated from 1 to 60 amps. Also, all voltage ratings range from 6 to a maximum of 60 volts. When you have solar panels with an amperage of 14, then you need a charge controller of at least 14 amps. 

Q. 5: How many watts can a 20-amp charge controller handle?

Ans: In concrete terms, you will have the possibility to drive at 480 watts with a 20-amp unit. It is important to consider that many solar panels work with variable solar energy.

In other words, solar energy is not the same throughout the day. On the contrary, it is very common for the energy to vary depending on the time of day. Besides, it is convenient that a charge controller is connected at all times, between the solar panels and the batteries.

In this way, the correct compatibility of the solar energy to the batteries can be obtained. In the same way, it is also possible to avoid the discharge that usually occurs in the batteries.

Q. 6: What is the disadvantage of PWM?

Ans: One of the main disadvantages of PWM is variation. In particular, this variation is because power is variable in the pulse width. To do this, we must consider that the transmitter can handle power. This is also true when we talk about the maximum pulse width.

Therefore, to obtain a good operation and use the communication correctly, the bandwidth must be big enough. It must even be large enough when compared to pulse width modulation. 

Q. 7: What is the purpose of MPPT?

Ans: Here, the main objective of this load controller is to extract the maximum possible power using an algorithm included in its design. In turn, this procedure is carried out, taking into account a set of safety conditions. 

Final Words

After analyzing each of the options listed here, you will be able to find the best MPPT charge controller for the money. It’s one of the best investments you can make for any home energy system. This will make it much easier to take advantage of the full potential of the electric current, or of a solar energy system.

On the other hand, you’ll avoid overspending on other options of questionable quality. As we have already mentioned, not all of these options will be able to protect you from certain electrical hazards. Some of them, such as polarity reversal, over-voltage, and short circuit, can be devastating at certain levels.

Therefore, it is always preferable to purchase a good charge controller, rather than spending money on many repairs. So, all that remains is to decide which option is best for you and to start increasing energy efficiency. Without a doubt, this is an excellent energy saving.
