Solar Panel Charge Controller Working Principle

Mppt or maximum power point tracking controllers are far more advanced than pwm controllers and enable the solar panel to operate at its optimum voltage for maximum power output.

Solar panel charge controller working principle.

They convert a higher voltage dc output from solar panels and a few wind generators down to the lower voltage needed to charge batteries. A charge controller charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries. Its purpose is to keep your deep cycle batteries properly fed and safe for the long term. A mppt or maximum power point tracker is an electronic dc to dc converter that optimizes the match between the solar array pv panels and the battery bank or utility grid.

Contrary to intuition solar panels work best at cooler temperatures. The mppt solar charge controller is the sparkling star of today s solar systems these controllers truly identify the best working voltage and amperage of the solar panel exhibit and match that with the electric cell bank. Detailed information on mppt charge controllers. Maximum power point tracking mppt.

Roughly a panel rated at 100 watts at room temperature will be an 83 watt panel at 110 degrees. The basic functions of a controller are quite simple. It prevents overcharging and may protect against overvoltage which can reduce battery performance or lifespan and may pose a safety risk it may also prevent completely draining deep discharging a battery or perform controlled discharges.
