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;
6)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).

1. How's the delivery time ?
A. usually it will take about 15 days for production
Q 2. Tell me the standard of package?
A. For the small capacity, it use carton, but for big capacity, we should use strong wooden case for protection.
Q 3. What kind of material of transformer?
A. 100% copper
Q 4.Would you accept to use our logo ?
A.If you have good quantity,it absolute no problem to do OEM.
Q 5.We want to know month capacity.
A. It depends on which model.For example for relay type small capacity , month capacity can reach near 20000pcs and big capacity near 50000pcs.
