How To Choose Right Solar Charge Controller

Solar charge controller functions.

How to choose right solar charge controller. If you are using one or more solar panels to charge your batteries you will need a quality charge controller with multi stage charging capability. This means if your battery is full it stops the charging and if your battery is reaching an unhealthy. An mppt charge controller may be doing well in one location but is not effective in another. The right solar battery controller rating influences the ability and performance of the solar power system.

For this reason mpptsolar has selected two charge controllers for solar panels one pwm and the other one mppt and decided to create this informative article to help you choose the right charge controller for your solar power system based on the type of panels and the battery you want to install. Finally we saw that the right type of solar charge controller pwm or mppt depends on the location temperature changes size of the system and your budget. The function of a charge controller is to regulate the charge going into your battery bank from your solar panel array and prevent overcharging and reverse current flow at night. The controller should also reduce the voltage to a trickle charge float voltage when batteries are fully charged to prevent overcharging.

It does this by using a transistor to shunt the pv charging circuit. Similarly pwm charge controller may not suits well in every size of the system.
