Steca SOLSUM PWM Charge Controllers 5.0 / 6.6 / 8.0 / 8.8 Amps 12/24 V Systems

Our newest, and fourth, generation of solar charge controllers sets new standards in solar technology. For the first time a solar charge controller is offered in the market which is equipped with an integrated circuit ( ASIC ) specially designed for solar charging. This integrated circuit, called Atonic(r), provides a charge controller with new functions. Atonicâ is more than protective device for your battery, and contains the most recent and innovative technology. Overcharge protection is provided by a pulse-with-modulated shunt controller which guarantees quick and gentle charging of the battery (characteristic IV curve ). Wear-resistant MOSFET transistors are used for the over discharge protection in this charge controllers, whereby a maintenance-free operation with an extremely long product life is ensured. Absolutely new in this price class is a cycle charging, boost charging and a temperature compensation which are regularly integrated in these charge controllers. An LED color display gives information about voltage of the accumulator.   Safety Features: Overvoltage protection by integrated varistor Wrong polarity protection at Battery and Module Proof against operation errors Built-in fuse Electronically short circuit protected Voltage-display by changing color  red 11,8 V yellow to red-yellow 12,3 V green 12,8 V Low voltage disconnection LVD   Charging Functions: Shunt regulator - fast and gentle charging Time-delayed overdischarge protection Temperature compensation by built-in sensor Automatic voltage adaption Cycle charging Boost charging Schottky diode MOSFET switch LED- display of charging function

Specifications:

The Steca Solsum Charge 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. One-year warranty. Other Features Include: � Temperature compensated overcharge and overdischarge � Automatically adjusts for 12 V or 24 V system protection � Operating temperature range is -25� C to +40� C � Protection against over temperature, battery overvoltage, � World Bank and CE certified module overcurrent, and load overcurrent
