Tips Before purchasing a power inverter

Tips Before purchasing a power inverter
Before you buy a power inverter, then there are several questions that should you ask the seller a power inverter
1. Component
Ask the seller if the inverter power components using IC alone or transformer + IC?
Inverter which uses + IC Transformer Component has good heat resistance so as not to be easily damaged and normally aging equipment can be for many years and even 10-15tahun and inverter using IC components although only relatively cheap but age is usually only a few months means a maximum of three months only, the from that match with your needs. If you only need the inverter only one to three months only, the inverter with IC components could be your choice and if you need an inverter for a long time then it could use a transformer component that you do not buy many times the inverter
2. Efficiency / Purity / Power out
Like the power inverter generator has efficiency / purity / power out.
Example of a power inverter which has a 90% efficiency with 1000watt the type that can be generated power is 900watt, and if the inverter which has only 40% efficiency can only be used 400watt
3. Frequency
Electrical frequency that is suitable for use in Indonesia is having a frequency at 50 Hz because there is a power inverter which has a frequency of 100 Hz so can not be used for electrical equipment in Indonesia
4. Wave
There are three types of wave power inverter
1. Square wave / box, in character and does not damage the electrical equipment suitable for electrical equipment in Indonesia
2. Waves of modified sine wave, nature does not damage the electrical equipment and is widely used because it is relatively cheaper than pure sine wave
3. Pure sine wave or puresinewave, nature does not destroy, and the price reached above 5juta s / d 15 million
