1.Q:Do you have your own factory?
A:Yes, we are professional manufacturer mainly in power inverter for many years. Our factory is located in Jiaxing, Zhejiang, China. We are A Sino-German joinit venture. We have product developing center and after-sale center in Germany.
2.Q:What kind of certification you have?
A:ISO9001,CE,ROHS and so on.
Our products could pass different labor testing according to different countries' requirements.
3. Q:How to choose suitable inverter?
If your load is resistive loads, such as: bulbs, you can choose a modified wave inverter. But if it is inductive loads and capacitive loads, we recommend using pure sine wave inverter. For example: fans, precision instruments, air conditioner, fridge, coffee machine, computer, and so on. Modified wave can be started with some inductive loads, but has effects on load using life, because capacitive loads and inductive loads need highquality power.
4. Q:How do I choose the size of the inverter?
Different types of load demand for power are different. You can view the load power values to determine the size of the inverter. Notice: resistive load: you can choose the same power as the load. Capacitive loads: according to the load, you can choose 2-5 times power. Inductive loads: according to the load, you can choose 4-7 times power.
5. Q:Connection between batteries and an inverter?
We usually believe that cables connecting battery terminal to inverter shorter is better. If you are just standard cable should be less than 0.5M, but should correspond to the polarity of the batteries and inverter-side outside. If you want to lengthen the distance between battery and inverter, please contact us and we will calculate the recommended cable size and length. Due to long distances using a cable connection, there will be a reduced voltage, which means that the inverter voltage would be far below the battery terminal voltage, this inverter will appear under voltage alarm conditions.
6.Q:How about your warranty?
A: We provide 1.5 and 3 years warranty for different products and whole life technical support.
