Product features:

·Featured with high reliability and low failure rate by using the advanced Double-CPU single chip intellectual control technology.

·Pure sine wave output.

·Small, light and artistic, benefited from adopting the SMD pastern technology.

·Cooling fan is intellectual controlled, and its working status is controlled by CPU, which mostly increased its service life and helps to save the power consumption, improve work efficiency and lower the working noise.

Applicable for:

·Solar electric energy generation.

·Wind power generation.

·Communication equipment.

·Industrial intellectual control system.

·Small sized emergency power supply system.
