How to choose a photovoltaic panel controller
The charge controller in your solar installation sits between the energy source (solar panels) and storage (batteries). Charge controllers prevent your batteries from being overcharged by limiting the amount and rate of charge to your batteries. They also prevent battery drainage by shutting down the system if stored power.
Regarding “what does a solar charge controller do”, most charge controllers has a charge current passing through a semiconductor which acts.
Typically, yes. You don’t need a charge controller with small 1 to 5 watt panels that you might use to charge a mobile device or to power a single light.
When it comes to charge controller sizing, you have to take into consideration whether you’re using a PWM or MPPT controller. An improperly selected charge controller may result in up to a 50% loss of the solar generated.
There are two main types of charge controllers to consider: the cheaper, but less efficient Pulse Width Modulation (PWM) charge controllers.The following factors should be considered when buying a charge controller: Your budget Lifespan of the technology Climate where your system will be installed: Certain charge controllers operate better in colder climates. How many solar panels you have and how high your energy needs are Size, number, and type of batteries you’re using in your system.

When selecting a solar charge controller, consider factors like battery compatibility, solar panel power, voltage, and charging current.
