Solar Charge Controller is an electronic device that controls the electricity flowing from the solar network to the battery. This ensures that the deep cycle battery doesn't recharge during the day and that the solar panels don't recycle and drain the battery at night. Some charge controllers have additional features such as lighting and load control, but power management is the main task.
Solar charge controllers are available in two different technologies i.e. MPPT and PWM. MPPT payload controllers are more expensive and very efficient than PWM payload controllers and are often worth the extra money. Silan is the top leading Solar charge controller manufacturer and supplier in India and here you can Buy Solar Charge Controller.
PWM solar charge controller: PWM solar charge controller means "pulse width modulation". They work by being plugged into batteries directly from the solar power grid. A 12 V solar panel can charge a 12 V battery. A 24v battery requires a 24v solar panel or solar grid, and a 48v bank needs a 48v grid.
MPPT solar charge controller: MPPT solar charge controller means "track point of maximum performance". It measures the panel Vmp voltage and converts the PV voltage into battery voltage. When the voltage drops according to the battery, the current increases. You can charge a 12 V battery with a 20 V solar panel.
If you try to charge a 12V battery with a 24V solar panel, more than half of the panel power will be discharged. If you try to charge a 24 V battery with a 12 V solar panel, you lose 100% of the potential of the panel and you can completely discharge the battery.
