The simplicity and high performance of the Steca Solarix PRS 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 give information on the battery‘s state of charge. Here, Steca’s latest algorithms are employed, resulting in optimal 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 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.

Distinguishing features of the product:

• Serial topology with MOSFETs
• Automatic detection of voltage
• Voltage regulation
• PWM control
• Multistage charging technology
• Current compensated load disconnection
• Automatic load reconnection
• Temperature compensation
• Negative earthing of one or positive earthing of several terminals possible

The basic functions of the controller include:

• Overcharge protection
• Deep discharge protection
• Reverse polarity protection of module (≤36 V),load and battery
• Automatic electronic fuse
• Short circuit protection of load and module
• Overvoltage protection at module input
• Open circuit protection without battery
• Reverse current protection at night
• Overtemperature and overload protection
• Load disconnection on battery overvoltage

Options:

• Evening or night light function pre-set in the factory or adjustable via Steca PA RC 100
• Parameterisation of function values via Steca PA RC 100
