NKD SINGLE-PHASE / NKW THREE-PHASE INVERTER WITH BUILT-IN CHARGE CONTROLLER

1. The product is an integrated intelligent inverter with built-in charge controller system designed for large photovoltaic power.Its built-in controller can realize charge management for a battery pack by multiple solar arrays to improve charge efficiency and life of the battery pack.

2. Thanks to its full digital vector control technology based on real-time processing by DSP,MCU and DDC,it has perfect protection functions and high reliability.

3. Its mains supply preferred mode,and battery preferred mode are all settable,thus making it easy to meet the different application needs of users.It has an LCD.

4. It is widely applied to large solar power generation occasions including families,schools,publish lighting,industrial and mining enterprises,frontier defense,sea islands,pasturing areas,etc.

1) High reliability.Frequency tracking,noise filtering and low distortion in inverter output because of double-conversion design;

2) High adaptability.A wide range of input frequency,which realize stable operation of fuel generators; 

3) High optimal performance of the battery.An intelligent battery management technology,which guarantees a longer battery life and decreases the times of battery maintenance;An advanced constant -voltage charge technology,which activates the battery to the most extent,saves the charge time and guarantees a longer battery life;

4) Overall and reliable protection.A power-on test function,which can avoid the faults because of hazards of the inverter;

5) Efficient IGBT(Insulated Gate Bipolar Transistor) inversion technology.Good high-speed switching feature,large-voltage and large-current operating characteristics ,and voltage drive of IGBT(The fifth-generation IGBT has a lower saturation voltage drop and higher operation efficiency and reliability).
