The charging current is blocked as soon as the battery is fully charged, all consumers are switched off before the battery is deeply discharged and damaged. A charge controller ensures that your battery is not overcharged so that it does not become too full or warm. This happens because the energy is automatically switched off by sensors when the occasion arises. Furthermore, the charge controller ensures that when the sun is not shining, for example at night, your electricity does not flow back to the modules. The solar charge controller should be able to handle about 10% more current (Ah) than the modules are ideally able to generate. Large LCD display with readable parameters.

Efficient use of electricity

The charging current controller is equipped with MPPT (Maximum Power Point Tracker) technology, which increases the efficiency of energy conversion in the solar system by up to 30%. The panels are thus used optimally in all weathers. The charge controller is ideal for small applications, such as in a caravan or mobile home.

WHY SHOULD WE USE A CHARGE CONTROLLER?

“The purpose of a charge controller is to prevent the solar panels from overcharging the batteries. It features a pulse width modulation series regulator that uses a series element that is switched on and off at a variable frequency with a variable duty cycle to keep the battery charged at the optimum voltage point.

What is the comparison between PWM and MPPT?

The PWM controller is essentially a switch that connects a solar array to the battery. The result is that the voltage of the array is pulled down close to the battery.

The MPPT controller is more sophisticated (and expensive): it adjusts its input voltage to harvest the maximum power from the solar array, and then converts that power to meet the different voltage demands of the battery plus load.

It is generally accepted that the MPPT will outperform PWM in a cold climate, while both controllers perform about the same in a subtropical to tropical climate.
