Q1. How many categories does it have according to the output waveform ?
A:Type one: Modified Sine Wave inverter, which uses PWM pulse width modulation to generate modified sine wave. Due to the usage of intelligent dedicated circuit and high power field effect tube, it greatly reduces the power loss and increases the soft-start function, effectively ensuring the reliability of the inverter. If the power quality is not highly demanded, it is able to meet the needs of most electrical equipment. But it still exists 20% harmonic distortion problems when running sophisticated equipment, can also cause high-frequency interference to radio communications equipment. This kind of inverter can meet the basic needs of most of our power, high efficiency, small noise, moderate price, and thus become the mainstream products in the market.
Type two: Pure Sine Wave inverter, which adopts isolated coupling circuit design, high efficiency, high stability of the output waveform, high-frequency technology, small in size, suitable for all kinds of load, can be connected to any common electrical devices and inductive load devices (such as refrigerators, electric drill, etc.) without any interference (eg: buzz and TV noise). The output of pure sine wave inverter is the same as the grid tie power we daily used, or even better, because it does not exist grid tie electromagnetic pollution.
Q2. Is the output voltage of our inverter stable ?
A: Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value by a multimeter. Actually the output voltage is quite stable. Here we need make a especial explanation : many customers found it is unstable when using conventional multimeter to measure voltage. We can say the operation is incorrect. Ordinary multimeter can only test pure sine waveform and calculate datas.
Q3. What is a resistive load appliances?
A: Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescents, electric fans, video broadcast, small printers, electric mahjong machines, rice cookers etc. All belong to resistive loads. Our modified sine wave inverters can drive them successfully.
Q4.What is the inductive load appliances?
A: It refers to the application of electromagnetic induction’s principle, produced by high-power electrical products, such as motor type, compressors, relays, fluorescent lamps, electric stove, refrigerator, air conditioner, energy saving lamps, pumps, etc. These products’power are far more than the rated power (about 3-7 times) when start. So only pure sine wave inverter is available to them.
Q5. What should be noticed when installing inverter?
A: Initially, let us know your requirements or application. Besides, We quote according to your requirements or our suggestions. Thirdly, customers confirms the samples and places deposit for formal order. Finally, We arrange the production.
Q6. Is it acceptable to print buyer logo on the product?
A: Yes. Please inform us formally before our product and confirm the design firstly based on our sample.
Q7: How to deal with the flaw?
A: Our products are produced in strict quality control system and the percent of pass is often maintained over 99.8%.
Q8: Do you offer guarantee for the 300W Car power inverter?
A: Yes, we offer 1-year warranty for all power supply.
Q1. Can I have a sample order?
A: Yes, sample order is acceptable to test and check quality for the first cooperation
Q2. What about the lead time?
A: Most of the model in the stock, sample lead time after receive payment 1-3 working days
Q3. Do you have any MOQ limit?
A: Low MOQ, 5 pieces for sample checking is available.
Q4. How do you ship the goods and how long does it take to arrive?
A: We often ship by DHL, UPS, FedEx, or TNT. It usually takes 3-5 days to arrive. Airline and sea shipping is also optional.
Q5. How to proceed with an order?
A: Initially, let us know your requirements or application. Besides, We quote according to your requirements or our suggestions. Thirdly, customers confirm the samples and places deposit for formal order. Finally, We arrange production.
Q6. Is it acceptable to print the buyer logo on the product?
A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.
Q7: How to deal with the flaw?
A: Our products are produced in a strict quality control system and the percent of pass is often maintained over 99.8%.
Q8: Do you offer a guarantee for the products?
