Product Description
4KW Pure Sine Wave Inverter With LCD Screen
Product Information:
This kind of solar / wind power off-grid inverter is pure sine wave intelligent inverter. Through the inverter power supply, DC 12v /24v /48v battery can be converted into AC 110v /220v, which used to the electronic products, such as water pump, air-condition, refrigerator etc. The solar power system consists of solar panel, solar controller, inverter, battery and other components.
According to used method can be divided into three types:
1. Only the converter;
2. Give priority to the use of solar energy;
3. Give priority to the use of AC.
You can customize the DC 36v inverter; Also can choose converting the AC 100v /AC 120v /AC 240v, which frequency is 50HZ /60HZ.
Product Picture:
Also we have another products' apperance ,the picture is in the following: (please kindly tell me what you want)
Product Advantage:
1. CPU intelligent management;
2. Latest American technical inverter;
3. Adopted best electronic components, stable quality, long-life;
4. The high conversion efficiency reach to 90%-99%;
5. Low power consumption, when power is in 1W-6W, under sleep state.
Product Feature:
1. DC batteries is converted into AC pure sine wave output;
2. Built-in transfer switch automatically transfers between inverter power and incoming AC power.
3. CPU management, Intelligent control, module design;
4. LED / LCD display function;
5. The inverters' high conversion efficiency can reach to 90%-99%, and it has lower power consumption.
6. It can match with all kinds of batteries, such as sealed lead acid battery, open lead acid battery, gel battery and kinds of lithium batteries.
Attention please: If you want inverters to match the lithium batteries, you should tell me the lithium batteries specifications.
7. Three-step intelligent charging mode available. It charges all kinds of batteries intelligently, so can be used as a charger. And the maximum charging current is adjustable.
8. It is also called dynamic inverter that has the advantage of strong overload capacity. For example, 1KW model can drive 1P air conditioning, and 2KW can drive 2P air conditioning etc.
9. This kind of inverter adopts latest American low frequency circuit design and new electric materials. The whole system is more stable, low malfunction rate, and long-life. There is no problem to use for more than 5 years under the normally using.
10. 1-year warranty plus life-time service.
11. Protection function:
(1) High voltage protection
(2) Under-voltage protection
(3) Over-temperature shutdown
(4) Automatic overload protection
(5) Short-circuit protection
