Solar Charge Controller
A charge controller, charge regulator goes between the batteries and solar panels. The current coming from the solar panel and going towards the battery is regulated by charge controller. This prevents overcharging by regulating the charge to the batteries.
The pulse width modulation (PWM) used to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors. This gradually lower the amount of power applied to the batteries as it gets closer to fully charged.
What is the use of solar charge controller?
This will help you to protect your solar batteries from overcharge. Control the PV input from the solar panel to charge the battery apart from the day consumption. If the system was connected on your electricity utility, charge controller will help you to protect the system battery overcharge. If the battery gets over charge required then the battery worn out very soon or even a safety issue of busting the battery. So charge control with built MPPT is more advance and effective way of preventing your system for long and safety life.
Charge control comes with various ampere power and brands, Some of the leading brand in charge controller is Luminous charge controller in india. It comes with 1-year warranty and price starts from 1200 Rs fro 10 amps solar charge controller.
Find the manual in the charge controller box and undestand the circut diagram how to connect the controller to your solar system.
MPPT solar charge controller
The maximum power point tracker or MPPT is an electronic DC to DC converter. This converts the higher voltage from the solar panel down to the lower voltage needed to charge batteries.
