SunWize Steca SLX

Visit SunWize

The SLX controllers use a unique state-of-charge algorithm, which provides a very accurate measure of battery SOC and enables precise triggering of control actions. This algorithm continuously adjusts battery capacity and SOC based on actual battery performance. The SLX controllers are programmable for voltage set point for equalizing cycle, battery type, and control by SOC or battery voltage. Three multicolor LEDs display SOC, system operating status and fault conditions. The SLX 0606 Night and SLX 1010 Night combine 24-hour timed control capability with light-level sensing. They may be programmed to switch loads on and off at hourly intervals and are ideal for applications such as streetlights, advertising illumination, bus kiosks, security systems and power for vacation or remote homes.

 

Features:

• PWM charging

• Precise SOC measurement & display

• Automatic load disconnect

• Automatic voltage sensing for 12V or 24V system

• Provision for remote audible disconnect warning

• Polarity reversal, short circuit and overload protection

• Temperature compensation

SunWize Steca Solsum

Visit SunWize

The SunWize-Steca Solsum Controller is an economical pulse-width modulated shunt controller designed for small and mid-sized systems. Using the most up-to-date and innovative technology, the Solsum controllers fulfill the task of overcharge and over discharge protection. The overcharge protection operates as a pulse-width-modulated shunt controller and guarantees faster charging of the battery. A tri-color 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. Solsum Controllers, certified for World Bank projects, ensure maintenance-free operation and long product life.

 

Other Features Include:

• Automatically adjusts for 12 V or 24 V system

• Operating temperature range is -25° C to +40° C

• World Bank and CE certified

• Temperature compensated overcharge and over discharge protection

• Protection against over temperature, battery overvoltage, module overcurrent, and load overcurrent

The SunWize-Steca controller uses an advanced control algorithm that sets new standards for solar charge technology. The state-of-charge algorithm combines battery temperature, battery voltage, and load discharge rate to determine the true battery SOC. The controller’s memory of discharge patterns enables the controller to know the degree of battery sulfation. This allows even greater accuracy towards determining true battery SOC. The self-learning controller automatically adjusts for the capacity and age of the battery. The resultant battery SOC is displayed within a 10% accuracy range. The patented hybrid regulator design combines both series and shunt technology for nominal power consumption. Maximum wire gauge for terminal: 4 AWG.

 

The Tarom features adjustable set points that are stored in the controller's memory. Available Tarom options are an external data logger, external shunts for measuring current and a remote temperature sensor. Other options include control modules that load shed or PV shed based on the battery SOC that is communicated with the controller over a DC databus.

 

Other Features Include:

• TUV and UL recognized component

• Automatically adjusts for 12 V or 24 V system

• Automatic battery equalization can be disabled when using gel or AGM type lead-acid batteries

• Protection against over temperature, battery overvoltage, module overcurrent, and load overcurrent

• Low voltage disconnect and a low voltage warning

• Tricolor information LED and tricolor “SOC” LED annunciating controller status, errors, and battery SOC

• IP 22 (NEMA 12) protection

• Operating temperature range is -25° C to +50° C
