2. Complete product specifications, different standards at home and abroad, the product into the United States, Britain, France and Japan, several major series of products can also be designed according to customer needs. 

3. The internal protection circuits to prevent the electrical pulses or voltage fluctuations, can withstand the compressor, the impact of TV monitors and other electrical power with greater security start, power switch can be completely cut off the internal circuit, to protect the battery from the fractured loss. 

4. The design of self-protection, making the time when the voltage is lower than 10V, it will automatically shut down to ensure that the batteries have sufficient power to start the vehicle.

5. Overheating or overload will automatically shut down when; Return to normal and then starts automatically.

6. No work noise, normal use can be run for many years without maintenance.

7. A variety input and output mode: 12V input, 24V input, the importation of cigarette lighter, battery directly; 220V AC output, 110V AC output, fully able to meet domestic and foreign users of the exchange of electricity demand.

Q1. What is inverter?
A: Inverter is an electronic equipment that turn 12v/24v/48v dc into 110v/220v ac.

Q2. How many kinds of output wave form for inverters?
A: Two kinds. Pure sine wave and modified sine wave. Pure sine wave inverter could provide high quality AC and carry various loads, while it requires high tech and high cost. Modified sine wave inverter load poorly not carrying inductive load, but the price is moderate.

Q3. How do we equip an appropriate inverter for battery?
A: Take a battery with 12V/50AH as an example. Power equal current plus voltage then we know the power of battery is 600W. 12V*50A=600W. So we can choose a 600W power inverter according this theoretical value.

Q4. How long can I operate my inverter?
A: The runtime (i.e., amount of time that the inverter will power connected electronics) depends on the amount of battery power available and the load that it is supporting. In general, as you increase the load (e.g., plug in more equipment) your runtime will decrease. However, you can attach more batteries to extend the runtime. There is no limit to the number of batteries that can be connected.

Q5. What's the difference between an inverter and inverter/charger?
A: An inverter simply converts DC (battery) power into AC power and then passes it along to connected equipment. An inverter/charger does the same thing, except that it is connected to an AC power source to continuously charge the attached batteries when AC utility power is available. In the case of a power outage, the inverter will automatically switch to battery power to provide power to connected equipment.
