|1+||US $60-80 / Piece|
Based on an MCU intelligent control technology, the product realizes solar charge and discharge management for batteries for longer lives of systems. It is widely applied to the solar power systems for families, schools, streets, industrial and mining enterprises, frontier defense, sea islands, pasturing areas, etc.
* Excellent performance because of MCU control and intelligent optimized SOC design;
* Longer batteries lives because of functions of overcharge function and overdischarge protection for batteries;
* Full automatic control such as electronic short circuit protection prevention;
* Visualization of operation status of the equipment through simple LED indicators and nixie tubes and one-button setting;
* An industrial chip provided for all control t enable equipment to operate in a cold, hot or humid condition;
* Crystal oscillator is used for timing control, featuring accurate control and having multi-stage single-interval fixed-time setting and independently settable multi-stage dual-interval fixed-time setting.
