Function of solar charge controller

A solar charge controller (or solar regulator) is a device which limits the rate at which electric current is added to or drawn from deep cycle leisure batteries in a solar electric system. It prevents overcharging which can reduce battery performance or lifespan, and may even pose a safety risk. It also prevents completely draining ("deep discharging") of a battery which can also reduce battery lifespan.
Basically, the function of the charger controller is set up / set voltage obtained from the hot sun for an entry into the battery voltage becomes excessive.

You need to buy the best quality solar charge controller to increase your battery's life. A cheap solar charge controller will result in short life of the battery and you will have to incur expenses by replacing your batteries regularly. Most of the solar kits have easy installation methods and if you follow the instructions step by step you will not face any challenges.

 The quality of your solar charge controller affects the lifespan of your batteries. When the battery has a charge deficit the lead plates which are inside the battery corrodes and this process of corrosion produces electricity. When you recharge your batteries, your plates are also rebuilt which supplies ample charge.
