Steca solar charge controllers make sure that the solar module charges the battery quickly and effectively, but also protects the battery against overcharging. If the electrical load discharges the battery, the solar charge controller, thanks to its precision in calculating  the state of charge, switches off the load at exactly the right moment, thus protecting the battery from the dangers of deep discharge. Furthermore, Steca solar charge controllers are equipped with an intelligent battery monitoring system. The most effective charging method is selected according to the requirements of the batteries. The solar charge controller is the central controlling component in all off grid systems, for it affects all the functions of the system. For this reason, it is important to choose a reliable, high performance, solar regulator.

NOTE: the battery should always be connected to the solar charge controller first. Then the solar module is connected to the solar module input of the solar charge controller. Only direct current loads are used in solar home systems. They are connected directly to the load output of the solar charge controller. This means the Steca solar charge controllers always show the battery‘s exact state of charge, and thus ensures optimal battery maintenance in all situations. Various energy-saving lights, Steca solar cooling units, DC-to-DC converters and other loads can be used.
