Product Description

MPPTcharge controlleror Maximum Power Point tracking ia an algorithamthat in charge controllers an used for extracting maximum available power from Solar PV module under awide variety of condition. The voltage at which the PV module can produce maximum power is called ‘maximum power point’(peak power voltage).Maximum power varies with solar radiation, ambient temperature and solar cell temperature, thus the MPPT solar charge controller is embedded with MPPT algorithm to maximize the Energy supplied to the battery from the module.

MPPT solar charge controllers are different than the traditional PWMsolar charge controllers in that they are more efficient, and in many cases more feature rich.MPPT solar charge controller allow the solar panel to operate at their optimum power output voltage, improving their producing performance by as much as 30%



The SCA25 MPPT is Averer smallest MPPT charge regulator and just as powerful as its big brother. With 200 to 700 Wp in solar panels, switchable output and buzzer, this Solar Charge Master is very well suited to small and medium systems.

The innovative technology in the Averer MPPT charge regulators increases the efficiency of the solar panels. The SCA25 MPPT charges your batteries up to 30% faster than PWM regulators – with the same number of panels.

MPPT charge regulator for all solar panels

Besides the traditional 36 and 72-cell panels, the SCA25 MPPT is also ideal for the inexpensive 60-cell panels. The high PV voltage makes it possible to connect several panels in series, significantly reducing the required cable length, installation time and power loss in solar cables. 

Easy to use, safe and flexible

The SCA25 MPPT is suitable for all battery types, including Averer Lithium Ion. The charging profiles for all types of batteries are pre-programmed and can be selected at the push of a button. The SCA25 MPPT is quiet and equipped with a very user-friendly, clear display. Built-in protection against overload, high/low battery voltage, overheating, short circuits and reverse polarity ensures that safety comes first. Moreover, the SCA25 MPPT has a robust casing and is protected against condensation in conformity with IP23.
