Beschreibung
Solar charge controllers Steca Solsum 2525 and 4040 are newly developed products based on our internationally renowned controller family Solarix PRS. 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. the controllers demonstrate impressive performance, are simple to use and offer unbeatable value for money.
Several LEDs in various colours give information on the battery‘s state of charge. Here, Steca’s latest algorithms are employed, resulting in optimal battery maintenance. The Steca Solsum charge controllers are equipped with an electronic fuse, thus making optimal protection possible. they operate on the serial principle, and separate the solar module from the battery in order to protect it against overcharging.
For larger projects, the charge controllers can also be equipped with special functions: e.g. with night light function and selectable charging plateau and deep-discharge protection voltages.Technische Daten
