It’s important to know the proper usage of a solar charge controller, if you are relying heavily on solar energy in your day-to-day life. PV charge controllers come in all shapes and sizes. Easy to install, a PV charge controller is required in almost every solar power systems that utilize batteries. Most solar panel controllers come with either a simple LED or digital displays. These days you will also find these PV controllers with built-in computer interfaces for better monitoring and control.
How it works?
Its primary function is to regulate the power passing from the solar panels to the batteries. They assist in properly maintaining the solar power system batteries by preventing them from being over or under charged, thus offering long life to batteries. The current passing through the solar charge controller charges the batteries used in various household items. This current can also be passed to the invertors for converting direct current (DC) to alternate current (AC).
At night or when solar modules aren’t generating any power, power can actually flow backwards from the batteries to the solar modules, draining the batteries. The solar charge regulator would ensure that this doesn’t happen. If solar energy is not actually passing from the solar panels to the circuit, it disconnects the solar panels from the batteries and stops the reverse flow of current.
Finding the Right PV regulator.
You will find numerous PV charge conrollers manufactures, but finding a good quality solar charge regulator matters. Don’t go for those cheaper ones, as they may hamper battery life and increase overall expenses in the long run. For a little peace of mind don’t ever compromise on quality.
