Solar Panel Charge Controller Working Principle

The charge controller regulates this 16 to 20 volts output of the panel down to what the battery needs at the time.

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. Detailed information on mppt charge controllers. 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. A charge controller charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries.

Maximum power point tracking mppt. Roughly a panel rated at 100 watts at room temperature will be an 83 watt panel at 110 degrees. Using this clever technology mppt solar charge controllers can be up to 30 more efficient depending on the battery voltage and type of solar panel connected. A charge controller is an essential part of nearly all power systems that charge batteries whether the power source are solar panels wind hydro fuel or the utility grid.

Its purpose is to keep your deep cycle batteries properly fed and safe for the long term. Contrary to intuition solar panels work best at cooler temperatures. The basic functions of a controller are quite simple.
