Description:

Power inverter is a kind of products which change the DC electricity to AC electricity. It has been widely used in cars, steamboats, mobile offering post and telecommunications, public security, emergency and other field.

This power inverter has adopted the international lead circuit design, with the advantage of small size, light, stable, and high conversion efficiency. It has five kind of protect function such as: input under voltage protection, input over voltage protection, overload protection, over temperature protection, output short circuit protection.

Solarway is a professional off-grid power inverter supplier, is a sino-german joint venture, mainly engaged in off-grid power inverter research and development, manufacturing and sales, we can provide customers with off-grid power INVERTER OEM and ODM. The factory is located in Jiaxing, Zhejiang Province, China. We have R & D Center and After-sales Service Center in Beijing, China and Leipzig, Germany.

1,Q:Why your quotation is higher than other suppliers?
A:In the Chinese market, many factories sell low-cost inverters, which are actually assembled by small unlicensed workshops, largely to cut costs and use substandard components for assembly. There's a major security breach SOLARWAY is a professinonal power inverter  R & D, manufacturing and sales enterprises, we deeply cultivated the German market for more than 10 years, each year exports about 50,000-100,000 power inverter to Germany and its surrounding markets Our product quality is worthy of your trust!

2,Q:How many categories does it have according to the output waveform ?
A:Type one: our NM and NS series 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: our NP, FS, NK series 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..

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 modified sine wave 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,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 effect for load using life, because capacitive loads and inductive loads need highquality power.

6,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.

7,How 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.

8,How to calculate the load of working hours requires configuration of the battery size ?

We will usually have a formula to calculate, but it is not hundred percent accurate, because there is also the battery's condition, the old batteries have some loss, so this is only a reference value: Work hours = battery capacity * battery voltage *0.8/load power (H= AH*V*0.8/W)
