Solar charge controllers are a crucial component in any solar power system. Charge controllers regulate the flow of electricity from your solar panel to your battery. They ensure that the battery is not overcharged and that it is not being discharged too quickly. Solar charge controllers come in two ways. Pulsewidth modulation (PWM) charge controller provides constant voltage battery charging by adjusting the duty ratio of the switches and has Higher charging efficiency, and longer battery life. PWM reduced the battery overheating. The second one is the MPPT (Maximum Power Point Tracking) is the most advanced solar charge controller, MPPT are more sophisticated and expensive. They calculate the VMP input voltage of the solar panel and then down-convert the PV voltage to match the battery voltage.
They can be connected in series or parallel and they come in different sizes and configurations. There are different types of charge controllers on the market, but which is best for you? EnCstore will help you choose the right one for your needs.
