Intelligent Solar Charge Controller using PWM and Microcontroller

Why do I require one?

A charge controller, or charge controller is fundamentally a voltage and/or current controller to keep batteries from cheating. It manages the voltage and current originating from the sunlight based boards heading off to the battery. Most “12 volt” boards put out around 16 to 20 volts, so if there is no regulation the batteries will be harmed from cheating. Most batteries need around 14 to 14.5 volts to get completely charged.

Do I generally require a Intelligent Solar Charge Controller using PWM and Microcontroller ?

Not generally, but rather for the most part. For the most part, there is no requirement for an accuse controller of the little upkeep, or stream charge boards, for example, the 1 to 5 watt boards. An unpleasant principle is that if the board puts out around 2 watts or less for every 50 battery amp-hours, then you needn’t bother with one.

For instance, a standard overwhelmed golf auto battery is around 210 amp-hours. So to keep up an arrangement pair of them (12 volts) only for upkeep or stockpiling, you would need a board that is around 4.2 watts. The prevalent 5 watt boards are sufficiently close, and won’t require a controller. In the event that you are keeping up AGM profound cycle batteries, for example, the Concorde Sun Xtender then you can utilize a littler 2 to 2 watt board.

Why 12 Volt Panels are 17 Volts?

The conspicuous question then comes up – “why aren’t boards simply made to put out 12 volts”. The reason is that on the off chance that you do that, the boards will give control just when cool, under impeccable conditions, and full sun. This is not something you can rely on in many spots. The boards need to give some additional voltage so that when the sun is low in the sky, or you have substantial fog, overcast spread, or high temperatures*, despite everything you get some yield from the board. A completely charged “12 volt” battery is around 12.7 volts very still (around 13.6 to 14.4 under charge), so the board needs to put out in any event that much under most pessimistic scenario conditions.
