Solar Panel Charge Controller Working Principle

Maximum power point tracking mppt.

Solar panel charge controller working principle.

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. 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. 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.

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

Detailed information on mppt charge controllers. The basic functions of a controller are quite simple. Contrary to intuition solar panels work best at cooler temperatures.
