How To Choose Mppt Solar Charge Controller For Pv Module

There are two types of charge controllers.

How to choose mppt solar charge controller for pv module.

What a solar charge controller does. It delivers power from the pv array to system loads and the battery bank. A mppt solar charge controller is one of several types of charge regulator. Lucky for you you are now equipped with the information that you need to choose the best solar charge controller for your solar power system.

As long as your pv system has rechargeable batteries you ll need a charge controller to protect it from being over charged especially caravan batteries of your roof mounted solar panel system. For example if pv module has to be placed far away from charge controller and battery its wire size must be very large to reduce voltage drop. 12v solar panels up to 70w. When the battery bank is nearly full the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off.

Through its control and regulatory functions the solar charge controller will prevent the overcharging of your solar system s battery. Flexcharge pv7d charge controller 7a 12v. Mppt solar charge controller allows users to use pv module with a higher voltage output than operating voltage of battery system. Think of a solar charge controller as a regulator.

The most important job of all solar charge controllers is to properly charge the batteries and to give them as long a life as possible. In fact the difference between the voltage supplied by the panel example 36v and the voltage required by the battery at that moment example 14v is not lost but is transformed by the mppt. Solar charge controllers are designed to ensure the control of the processes for charging and the discharge of your solar power battery bank within the solar panel powering system. 12v solar panels 5w 45w.

12v solar panels up to 120w. Pulse width modulation pwm maximum power point tracking mppt the difference between these two types of controllers is that the pwm is not as efficient the mppt. Mppt stands for maximum power point tracking and a mppt charge controller is used in the very common case where your solar array s voltage is higher than your battery bank s voltage. Unlike the pwm charge controller which considers only the current in order to charge the battery the solarix mppt controller considers all the power of the solar panel therefore voltage and current.
