The Steca Solsum 4040 solar charge controller is a further development of our internationally popular Solarix PRS controller family. Thanks to the increased module and load current, they are now also suitable for even larger systems.
The devices also feature an integrated USB charging socket for charging smartphones and tablets. They impress with their simplicity, performance, and unbeatable price-performance ratio.
Several LEDs in different colors provide information about the battery's state of charge at a glance. Modern Steca algorithms are used to ensure optimal battery maintenance.
Steca Solsum charge controllers are equipped with an electronic fuse, offering optimum protection. They operate on the serial principle and disconnect the solar module from the battery to protect against overcharging.
For larger projects, charge controllers can also be equipped with special functions, such as a night light function and selectable charge termination and deep discharge protection voltages.
