Solar Charge Controller

MADE IN GERMANY

Steca Solarix PRS

The simplicity and high performance of the new Steca Solarix PRS solar charge controller make it particularly attractive. 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 charge status of the battery. Here, Stecas latest algorithms are employed in order to guarantee optimal battery maintenance. The Solarix PRS charge controllers are equipped with an electronic fuse, thus ensuring the optimal protection. They operate on the serial principle, and separate the solar module from the battery in order to protect it against overcharging. The Solarix PRS charge controllers are universal charge controllers, which means they can be used with lead-acid batteries or gel batteries without the need for complex configuration settings. For larger projects, the charge controllers can also be equipped with special functions. These include the night light function, and selectable charging plateau and deepdischarge protection voltages.

Charge Controllers

Steca Solsum Controller The Steca Solsum Controller is an economical pulse-width modulated shunt controller designed for small and mid-sized systems. The overcharge protection operates as a pulse-width-modulated (PWM) shunt controller and guarantees faster charging of the battery. A tricolor LED indicates three ranges of battery voltage and a green LED indicates array current. These controllers include temperature compensated charging, MOSFET transistors and fuse protection. Other features include automatic adjustment for 12 or 24 Vdc systems, protection against extreme temperature, battery voltage, module overcurrent and load current. Temperature compensated overcharge and over-discharge protection is also built in. Solsum Controllers, certified for World Bank projects, ensure maintenance-free operation and long product life. 2-year warranty.
