FAQ

FAQ:

1,Q:Why your quotation is higher than other suppliers?
A:In domestic market, the high and low inverter brands are mixed together. There are many
low-cost power inverter is actually some assembled small unlicensed workshops,crudely 
to reduce costs and use of substandard components for assembly, there is a very big security risk!
In order to protect the pro personal and property safety, please do not covet low 
price, be sure to choose a reliable inverter!
..............................................................................................................................................................
2,Q: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.
..............................................................................................................................................................
3,Q:What is a resistive load appliances?
A:Generally, 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 power inverters can drive them successfully.
..............................................................................................................................................................
4,Q: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. only pure sine wave inverter is available to them.
..............................................................................................................................................................
5,Q:What should be noticed when installing inverter?
A:Put the product in a place where is well ventilate,cool, dry and water-proof. Pls do not stress and
do not put foreign objects into the inverter.Rember turn on the inverter before turn on the appliance.
