STECA SOLSUM PWM
SOLSUM-4040 – PWM Charge Controller
Solar charge controllers Steca Solarix 2525 and 4040 are newly developed products based on our internationally renowned controller family Steca PR. With increased module and load current, the controllers are now also suitable for even larger systems. The devices also feature an integrated USB charging port for charging smartphones and tablets.
Use of the latest charging technologies combined with state of charge determination enables optimal battery maintenance and module power monitoring. A large display informs the user about all operating modes with the aid of symbols. The state of charge is represented visually as a level meter. Data such as voltage, current, and state of charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter which can be reset by the user.
