Most people that own residential electric vehicles don't consider the advantage of an intelligent solar charge controller and don't take the time to understand its benefits. And they are missing out on a good investment in the long run.
The first thing that you need to understand is that there are two forms of solar charge controllers and one is a solar panel controller and the other is a solar charge controller for the battery pack. They both serve the same purpose but the latter has some unique benefits over the former.
The solar charge controller is what monitors the charge in the batteries and then switches on the charging circuit. It does this by utilizing some of the energy from the sun as a source of power.
This can work best if the sun is up most of the day. But if the sun is lower in the sky during the daytime, then the solar charge controller is useless because it cannot be used effectively.
On the other hand, a solar charge controller for the battery pack is a more modern unit. It's comprised of a microprocessor chip that can tell the difference between sunlight and heat from the sun(20A MPPT solar charge controller: solar charge controller).
It will then determine that the battery pack needs to be fully charged to continue the process. And that's why it is a better idea to buy a charge controller that uses solar energy to initiate the charging process.
The efficiency of the solar charge controller for the battery pack is higher than that of the solar panel controller. And this means that you can save a lot of money by simply buying a solar charge controller for your battery pack instead of buying a solar panel.
The solar charge controller for the battery pack also has a back-up system so that if the sun isn't up high enough during the day, it will still initiate the charging process. And this way, your battery pack will still be fully charged up when the sun rises.

On top of the savings on your electric bill, you also save on the amount of energy that you use to recharge your car with the solar charge controller. And this in turn means a lot of money saved.
Another advantage of a solar charge controller for the battery pack is that you don't have to worry about it overheating or failing because of the sun. It is durable enough and has a big enough battery capacity to withstand any of the weather.
You also don't have to worry about anything at all if you need to uninstall the solar charge controller from the car. Just simply unplug it from the car's electrical system and then you can start using your battery without the need for a charger.
So next time you are thinking about investing in a new car, do yourself a favor and buy a solar charge controller for your battery pack. You will be glad you did and the savings on your electric bill will be just icing on the cake.
