1. Intelligent design, simple structure, control powerful, stable performance, safety and
reliability of the products.
2. Should choose MPPT fan charging ways, charging efficiency than ordinary PWM way more superior
3. Booster charge function, solve the charging efficiency, low because of fan speed low of
difficult problems
4. Choose a big size LCD display, users all parameters directly visible
5. A human nature of the key operation, all of the parameters according to the request of users
can adjust for customers in various environment in use
6. Choose a PWM stepless uninstall way.
7. Should the output state has a variety of functions, often power/half power/in different periodof
customization features
8. Liquid crystal display battery charging electric current and voltage
9. Utility the complementary function, uninterrupted soft handoff, guarantee load to continue to
work. (this function should be customized)
10. Digital intelligent control.
