Top 8 Best Solar Charge Controller For Your Solar Panels

Have you spent a lot setting up your Solar system or you just about setting up your solar panel, and you are worried that the batteries might not last as much as described by the engineer due to poor usage? The solution is here, to protect your batteries, you need the best solar charge controller for your solar system, to avoid the batteries getting damaged due to overcharging. The solar charge controller will help to optimize your batteries, thus bringing to the barest minimum, the tendencies of your batteries getting overcharged and also prevent it from discharging unnecessarily.

There are presently so many variants of solar charge controller in the open market as at today and we know you might be confused as to identifying the best solar charge controller. The aim of this article is to, first of all, help you make the right decisions on the appropriate solar charge controller to buy. We would be showing you things/pointers to look out for in a solar charge controller before buying it. Also, we would review the best solar charge controllers in the market.

Things to Look for When Buying a Best Solar Charge Controller

A solar charge controller is very important and delicate to your solar system because, without the right solar charge controller, your whole solar system would not work efficiently as you would be constantly faced with overcharging and discharging. To know the best solar charge controller, you must consider the following important features.

The Type of Solar Charge Controller

Basically, there are two major types of Solar Charge controller in the open market for now. They are the MPPT (Maximum Power Point Tracking) controller and the PWM (Pulse Width Modulations).

The MPPT is designed to provide larger effects than the PWM. They are advanced and have varying functions which certainly helps you to protect and extend the lifespan of your Solar system batteries. However, the PWM is kind of elementary and his available for very cheap prices.

Manufacturer’s Pedigree

Another thing to consider before placing your money on any Solar Charge Controller is the pedigree/history of the manufacturer. As you are aware, there are many Solar Charge controllers in the market as at today, so an easy way of sieving the poorly made solar charge controllers away is by checking the history and also the pedigree of the manufacturer.

Durability

The Solar Charge Controller is designed to function almost 24 hours a day and 7 days a week so you don’t want to fall into the trap of buying Solar Charge Controllers that are not durable. Buying Solar Charge Controller that are not durable could indeed be frustrating and exhausting. In determining the durability of the Solar Charge controller, you have to check the components in which the Solar Charge Controller is made with. This will certainly show how durable the controller is.

Voltage consideration

Before deciding the best Solar Charge Controller for your Solar Panel, it is pertinent to know the type of voltage of your Solar Panel. There are varying types of the voltage of 12V or 24V and they tend to have a voltage of resume power supply of 11.8V or 23.6V and a charging current of 10A.

Although most users readily buy the 12V unit, it doesn’t necessarily mean it is the best. The best Solar Charge Controller for your Solar panel is the one that has the voltage as instructed by the manufacturers of your solar panel. When you buy a Solar Charge Controller that has below or above the voltage requirement, it would certainly not provide the desired result.

Waterproof

This is a necessary feature to consider before buying Solar Charge Controller. This is because Solar Charge Controller although could be placed indoor are also placed outdoor. You don’t want to buy a Solar Charge Controller that would get damaged due to water. To know whether the Controller is waterproof or not, you should check the specification and confirm from the seller.

Warranty

It is common knowledge that the Solar Charge Controller is expected to last as long as your Solar System. Just like every other mechanical device, they are susceptible to factory damage. So, you want to be sure that the Solar Charge Controller would be replaced when any fault is detected. Aside from the fact that the product would be replaced if any fault is detected, the warranty also gives assurances that the product is well fabricated and the manufacturer is willing to vouch for it.

Most defective and not well fabricated Solar Charge Controller don’t have a warranty. The Manufacturers are aware of the quality of the controller and thus, avoid giving warranty for the controller.

The next step is to add holes in the lid for you to be able to run the wires for the charge controller and the inverter. This is dependent on where you want to place the Solar charge controller if you intend to place it outside, then it should be visible. If you want it concealed, you could just easily put it inside the container for a more cloaked look.

Step 6: Connect the Inverter

The next line of action is to connect the Solar charge controller and the inverter to the batteries. Please ensure that the inverter is turned off before attempting to connect it. Also, for safety reasons and to avoid damaging the solar system, it is advisable that the charge controller is not connected to the solar panels yet.

Step 7: Connect the Solar Charge Controller

At this stage, all parts of your solar system should have been wired together. What is now to be done is to connect the solar charge controller to the solar panels and turn the inverter on and check to see that it works.

Step 8: Start enjoying your solar charge controller

You can now start enjoying your Solar Charge controller
