Steca Solar Charge Controllers

The solar module array has to be adjusted to the local sunlight conditions and the system‘s energy requirement. In order to avoid stagnation times, the PV generator must also provide enough power during months with little solar radiation in order to cover the requirement of the connected loads.The chosen solar charge controller must also be suitable for the maximum short-circuit current of the PV generator and the maximum load current. In some applications, however, technical properties also play an important role in the choice of solar charge controller. This may mean that a high-performance solar charge controller with corresponding additional functions is used in a system with a low output.In order to keep the initial investment small, we recommend planning the size of the PV generator and battery according to the current energy consumption and choosing a solar charge controller which will allow the system to be expanded later.

Steca Solarix PRS

PRS 1010, PRS 1515, PRS 2020, PRS 3030

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 emulate a tank display, which gives 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.

Steca Solarix

2401, 4401

The solar charge controllers Steca Solarix 2401 and 4401 are optimally suited for inverter systems. Inverters have to be connected directly to the battery. The Steca Solarix 2401 and 4401 combine basic solar charger functions with a 40 A high-performance charge controller. It is available as 12 V / 24 V and 48 V system. This makes the solar charge controller very cost effective.

The load current is limited to 10 A. The charging processes are based on the voltage level, which can be individually set with the help of four buttons behind the front casing.

 

 

Steca PR

PR 0303, PR 0505

The Steca PR 0303 and PR 0505 solar charge controllers are optimally suited for use in small solar home systems with module currents up to 5 A.

A 75 Wp module can be connected, which easily allows operation of lamps, radios and a small television. All loads can be switched off using the manual load switch on the controller. The extremely low own consumption makes the Steca PR especially suitable for professional applications in telecommunications and traffic management technology. Since this is a serial controller, it is extremely flexible in the type of power source that can be connected. The electronic fuse makes the controller completely maintenance-free and robust.

Steca PR Night

PR 0606N, PR 1010N


The Steca PR Night is designed for operating automatic night light systems and is suitable for solar systems of up to 300 Wp module output.

This controller is thus especially suitable for streetlights, bus stops, advertising lighting and other similar applications. The charge controller determines the actual solar time via the solar module. This integrated clock can be used to define how long after sunset, or before sunrise, the light is to be switched on or off.

 
 

Steca PR

PR 1010, PR 1515, PR 2020, PR 3030


The Steca PR 10-30 series of charge controllers is the highlight in the range.

The latest charging technologies, combined with a Steca-AtonIC state of charge determination which has been significantly improved once again, result in optimal battery maintenance and control of the module output of up to 900 Wp which can be connected to it. A large display informs the user about all operating modes with the aid of symbols. The state of charge is represented visually in the form of a tank display. Data such as voltage, current and state of charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter which can be reset by the user.
