PWM Solarix PRS


Bolanmu SolarixPRS


The simplicity and high performance of the Bolanmu Solarix PRS solar charge controller make it particularly appealing. At the same time, it offers a modern design anda 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, Bolanmu’s latest algorithms are employed, resulting inoptimal battery maintenance.The Solarix PRS 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 thebattery 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 anddeep-discharge protection voltages.
