Best Solar Charger Controller

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:

  1.  GTPower 6000W Peak 1800W Low Frequency Pure Sine Wave Inverter Charger Controller
  2.  Victron SmartSolar Charge Controller with Built in Bluetooth
  3.  Sungoldpower 2000W Peak 6000W APV Low Frequency Pure Sine Wave Inverter Solar Charger Controller
  4. Zamp Solar 30A Controller
  5. 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:

        You can prevent current from backflowing to the solar panel

        It’s easy to regulate the power that goes from the solar panel to the batteries so that it doesn’t fluctuate and damage your battery units

        You can ensure that the batteries are fully charged

        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.
