The simplicity and high performance of the solar charge controller make it particularly appealing. At the same time, it offers a modern design and a convenient display, all at an extremely attractive price. Several LEDs in various colours emulate a tank display, which gives information on the battery‘s state of charge. Here, latest algorithms are employed, resulting in optimal battery maintenance. The 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.
