What Is An MPPT Solar Charge Controller And Who Is This For
A charge controller is an integral of most (if not all) power systems that need batteries. It regulates the energy flow from any source (like solar, hydro, fuel, and many others) to its battery bank.
A maximum power point tracking or more commonly known as MPPT is a kind of charge controller. It is set as an electronic DC converter that matches the solar array’s energy to the battery bank. An MPPT is one of the most efficient charge controllers available today.
You may wonder what’s unique about this kind of charge controller. It increases the efficiency of your solar arrays, so no energy is put to waste. There may be some discrepancies in the energy that your solar panels produce and the energy that your battery needs. The MPPT charge controller makes this flow so much easier and keeps all the energy it comes across with.
It is ideal for those who want to make the most of the sun, those who want to save more on energy, and those whose panels aren’t exposed to that much sunlight. That way, your panels can be more efficient as any solar energy that hits them is stored. This is also beneficial for home, industrial, and commercial use.
How Does It Work
The solar power system you must rely mostly on solar energy will need a solar panel. These solar panels work on their own. They absorb solar energy on the photovoltaic (PV) cells that are embedded on the panel. Unfortunately, they aren’t so smart.
So are the batteries. And sometimes, they cannot be in sync. Although they still produce quality solar energy, they might waste some as they can’t communicate properly without a suitable charge controller.
The MPPT works by identifying the top-tier voltage that matches the PV panel to your battery. That way, your battery will not be overcharged and will be charged in the shortest amount of time possible. As its name implies, it tracks out the maximum power point.
The MPPT is also responsible for keeping the panels in high-efficiency as they maximize having solar energy in all conditions. This latest innovation not only produces more power, but also protects your battery from overcharging.
This kind of charge controller gives you 10-30% of extra power than the standard charge controllers. With the latest mechanism of MPPTs, energy, and time in charging the batteries are not wasted, and the panels are in excellent condition for absorbing solar energy.
Are MPPT Controllers Worth It
Shifting your energy consumption to solar power is already worth it. It is eco-friendly, and it saves so much money in the long run. And the top-rated part is that it just utilizes the energy from the sun that shines daily. If this energy sheds some light on your solar panels, you’ll never run out energy for your appliances. And investing in an MPPT is even more worth it.
Having an MPPT is even maximizing out the capabilities of your solar power setup. As the standard charge controllers can’t regulate the asynchronous power of the PV panel and your batteries, this will keep efficiency up and give you the satisfaction of saving more money in the future.
How We Picked And Tested
Cyberspace can be helpful and dreadful at the same time. A single MPPT solar charge controller review can make a difference in how you view things and even give you bias on what to buy. These products have been researched, and their brands have been checked to ensure that these MPPT charge controllers are of high quality.

The ones in the reviews have very high tracking efficiencies. Most, if not all, currently have an approximate of more than 97% of tracking efficiency. If the actual and the available solar energy is matched at those rates, you will surely get the most out of your PV panels. This will also keep the battery life in good shape for an extended time.
State-of-the-art innovations have made it possible to not only keep the batteries protected but the PV panel and the charge controller as well. The reviewed charge controllers commonly have a protection system that prevents batteries from overcharging and over-discharging.
Your PV panels are also protected from short-circuiting, over-currents, and reverse polarity. And overall, the internal mechanisms of these units can protect itself from overheating.
The kind of battery will always be up to the user’s preference. They might have some bad experiences over the other. These reviewed ones cater to most battery types. Both lead-acid and lithium batteries are compatible with the ones we’ve carefully picked.
Both positive and negative grounding are included to give the consumers the liberty to choose which one they will have. Those who are still about to shift to solar energy can have the freedom to decide on the grounding first.
For those who already have their systems, both negative and positive ground for charge controllers add to your convenience.
Most of the MPPT charge controllers are already ready to connect to your mobile phones through their applications. Bluetooth connections are also integrated for easier access. Some even come with PC software, so customizations and monitoring are done on the bigger screen.
Shelling out an extra amount just to get more power can be draining. Investing in solar power is already a huge financial consideration, and this is not an exemption. Having the most suitable cheap MPPT charge controller can be a boon or bane for your solar power systems.
The mentioned brands are reputable to provide quality charge controllers that don’t necessarily break your wallets. And the units mentioned are reasonably priced for all the features and customizations that they provide.
Frequently Asked Questions
Who makes the most suitable MPPT charge controller?
There are a lot of MPPT charge controllers in the market today. While some brands are still trying to establish themselves in the solar power industry, these have already built their name in the game.
- Victron Energy
These brands are known to produce more than one kind of MPPT model and have been continuously improving their charge controllers. Some of them pioneered in the industry, and some have just settled their footing but have already captured most consumers’ trust. These brands have high-satisfaction rates in providing out the most suitable ones in the market.
What size MPPT charge controller do I need?
When you already have a solar panel and a battery, you need to make sure that these are compatible with each other, before you buy one MPPT charge controller. Some solar generators already have a built-in charge controller, so make sure that this issue won’t be in the way when you’ll upgrade your charge controller.
Having the right size is vital for your PV system. The size of the charge controller that you will need will depend on the solar panel’s current (amp). The solar system’s voltage will also matter.
If, for example, if you have 900W solar array, the next thing you need to consider is your battery’s voltage, for instance at 24V. You can divide your solar array wattage over your battery voltage, and you will get 37.5 amp. But you will still need to add about 25% of current increases, so that will give you 46.8 amps. We can then round this up for an easier choice of the right MPPT. So, you will need a charge controller that is at 24V, 50 MPPT.
Calculate the voltage and the amperes that you need, and you will have the right MPPT that will work most pleasing for the solar power setup you already have.
MPPT and PMW charge controllers: what’s the difference?
A charger controller MPPT technology has a higher solar energy conversion efficiency (about 95%) than PWM devices (about 75%). The former also boasts more features and can handle higher voltage and amperage. On the other hand, the latter is more affordable and tends to be used with small-scale solar systems.
Therefore, solar MPPT charger controllers work top-tier with systems containing 60 to 72 photovoltaic panels, allowing users to wire them in series. In contrast, PWM controllers are more suitable for 32-panel systems and can only accommodate a parallel setup.
Another difference is temperature tolerances. PWM controllers are only suitable in hot or warm climates, while MPPT devices work in any environmental temperature. It is worth mentioning that cold temperatures can increase solar panel voltage output, allowing MPPT controllers to capture the energy increase.
Is the MPPT charge controller always better?
Not necessarily. Even the top solar charge controller with MPPT technology will mean nothing to some folks in the same manner as some families might consider a PWM device useless. These solar charge regulators have pros that some homeowners might find appealing and cons they can do without.
For example, an MPPT charge controller is better than a PWM system if you have a large solar system capable of producing more than 400 watts. It is about twenty percent more efficient in converting solar energy than PWMs (95% vs. 75%), making it a better system for households that want efficiency.
However, households with modest solar energy output (<400 watts) will find MPPT overkill. Small-scale solar systems will do just fine with PWM devices instead of spending an unnecessary amount of money for a much more expensive MPPT model.
How long does an MPPT charge controller last?
The longevity of an MPPT solar panel charge controller is brand-dependent, although other factors can also limit its operating lifespan. Some manufacturers offer a five-year warranty, giving homeowners peace of mind that their charge controllers will last at least that long. Real-world experiences suggest these devices can last at least a decade.
How to use & install?
Having the basic knowledge of how a charge controller works will give you a glimpse of how to use it. The installation process can also be done alone or with an expert. But most of these charge controllers come with instructions on how they can be assembled at your comfort. Make sure that you have all the parts and the unit with you right before installation.
- Check out the diagram
Upon purchase, a diagram on how to make the connections comes with it. Check the description if you have the right materials and connectors before installation.
- Check the wiring terminals
