Working Mode Optional:

Working mode
(Optional)
01AC mains priority
Always use AC mains as priority input to provide AC output and automatically charge the battery, only
stops charging when battery is fully charged, and only starts DC to AC converting untill AC mains is off
02Energy saving
Loading≤10% automatic shutdown, loading≥11%-100% automatic turn on
03DC battery priority
Always use DC battery as priority input to provide AC output, for 12V system, when battery≥13V, starts
DC to AC converting; when battery≤10.5V during converting, switch to AC mains mode to provide AC
output and automatically start charging the battery (for 24V/48V system, multiply by 2/4 accordingly)

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 solar power inverter is actually some assembled small unlicensed workshops, it 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 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 pure sine wave solar 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. So 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 to turn on the inverter before turn on the appliance.
