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.

Solar panel charge controller working principle.

Its purpose is to keep your deep cycle batteries properly fed and safe for the long term. The charge controller regulates this 16 to 20 volts output of the panel down to what the battery needs at the time. A charge controller charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries. 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.

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. Maximum power point tracking mppt. Contrary to intuition solar panels work best at cooler temperatures. 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.

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. Roughly a panel rated at 100 watts at room temperature will be an 83 watt panel at 110 degrees. Detailed information on mppt charge controllers.
