The best solar charger controller can be used to make sure that you do not overcharge and subsequently damage the solar energy storage system you have set up.
I find that using a solar charger controller allows you to regulate your battery so that you don’t exceed its voltage capacity.
Since there is often a lot of confusion about choosing the best charger controller for your needs, this guide will help you make an the best decision.
Check out the best controllers at the links below if you are in a hurry, or read on for the full reviews:
- GTPower 6000W Peak 1800W Low Frequency Pure Sine Wave Inverter Charger Controller
- Victron SmartSolar Charge Controller with Built in Bluetooth
- Sungoldpower 2000W Peak 6000W APV Low Frequency Pure Sine Wave Inverter Solar Charger Controller
- Zamp Solar 30A Controller
- Sungoldpower 3000W Peak 9000W Pure Sine Wave Inverter Solar Power Charger Controller
Choosing the right solar charger controller is important.
There are two main types that you can choose from: maximum power point tracking (MPPT) and pulse width modulation (PWM).
The PWM is not nearly as effective as the MPPT, which happens to be much more common.
MPPT controllers allow you to connect panels to have higher voltages with lower amps.
Consider the number of cells that you have in your solar panels, as well as the voltage of your battery bank.
By choosing a solar charger controller based on these two factors, you can choose the best one for your needs.
Why You Need a Solar Charger Controller
When you use a solar charger controller with your home solar system you will enjoy four main benefits:
● It’s easy to protect your batteries from becoming completely discharged
What to Look for in a Solar Charger Controller
I find that to choose the right solar charger controller for your solar panels, you need to know a little basic information about your setup, as well as your needs.
Make sure to take into consideration the type of charger controller that is recommended for your type of solar system.
It’s also important to consider how much maintenance your charger controller will need, as well as how much maintenance will cost.
If you live in a hot climate, then you need to find a charger controller that can withstand the higher temperatures.
Additionally, make sure that you choose a charger controller that is the right option for your size system. Some charger controllers are better used with smaller solar systems, while others can handle the loads of larger systems.
How to Use your New Solar Charger Controller
It’s surprisingly easy to use a solar charger controller.
While many people think that you have to constantly monitor your charger controller, I don’t find that to be true.
Rather, you can easily connect your charger controller to your solar panel and your battery, and once it is set up and running correctly, it will monitor your battery condition and protect it from damage.
Some solar charger controllers have LCD displays that make it easy for you to customize charging.
This makes your solar circuit more controlled and advanced, but for people just getting started, I find that a traditional controller without all of the additional features provides you all of the benefits that you need.
As you get more comfortable using a charger controller, you may find that you want to use one that syncs with your phone so you can control it via an app.
Is There Any Controversy?
The only controversy that you will find around solar charger controllers is when people don’t think that they need to use them as a part of their home solar systems. I believe that neglecting to buy this powerful, yet inexpensive, piece of equipment can set you up for major problems with your solar system.
Precautions to Take When Using a Solar Charger Controller
If you want to go completely off the grid, then you will need to choose the right solar charger controller for your home, as it will help protect your battery.
Choosing between PWM and MPPT controllers is the biggest decision that you are likely to face.
Pulse Width Modulation (PWM) controllers are standard and generally cost less than their counterparts.
They slowly reduce how much power enters your battery as your battery approaches capacity.
When you opt for a PWM controller, you have to make sure that your battery and your solar panel system have the same voltages.
I find that this means that these controllers are a better option if you have a smaller DIY system with lower voltage panels.
On the other hand, Maximum Power Point Tracking (MPPT) controllers tend to be more expensive, but can adjust their input and output power to be the same as the attached battery.
These controllers are much more effective and I think that they are ideal for enjoying all of the power that your solar panels offer, especially when charging a larger home system.
Best Solar Charger Controller
This powerful solar charger controller is durable, easy to install, and offers unique features that allow you to control your power without a lot of effort or problems. Users can easily turn the unit off and on, rely on eight preset selections for battery type when charging, and even use less power than other types of units, making this a good choice for many people.
Unlike some other charger controllers that don’t offer easy monitoring, this option from Victron makes it easy to control the charger via some smartphones and other devices. Can be used up to 220W at 12V and 440W at 24V. Comes with a five-year warranty in case of problems, and is very affordable.
Not only will you enjoy all of the features in a standard solar charger controller, but with this product you can also make your solar system much easier to wire and to handle. With multiple alarms designed to alert users to problems and to troubleshoot issues with the solar system, this product is easy to set up and to use.
● Costs more than other controllers on the market
When this product is mounted in an indoor location so that it is protected from the rain, not only will it safeguard your batteries from damage, but it also makes it very easy to monitor battery use and charging. Unlike other controllers that are a little more difficult to read, this one is ideal for beginners who may otherwise struggle with understanding how the controller is working.
This charger controller is easy to install and makes it easy to adjust the charging current. The LCD screen, while small, is easy to read and provides plenty of information about how the controller works, as well as information about any alarms that may go off when it is in use. Thanks to the remote, you can easily adjust the controller.
I think that if you are just getting started with a solar power system at your home, then you will want to choose the Zamp Solar 30A Controller.
It is not nearly as overwhelming to look at and to use as some of the other available charger controllers.
This means that if you are new to the world of solar power and are just learning how to use a controller to protect your battery, that you can easily set this option up without a lot of work.
Unlike some of the other controllers on this list, specifically the SUNGOLDPOWER 3000W Peak 9000W Pure Sine Wave Power Inverter, it is easy to connect this controller to your solar power system without worrying about wrong connections.
This product will offer you all of the benefits of more expensive solar charger controllers without being so difficult to operate.
