# WD Series Low Frequency Power Inverter 

The low frequency solar inverter, is a converter that converts direct current (battery, battery bank) into constant frequency and constant voltage or frequency and voltage regulated alternating current (usually 220V, 50Hz pure sine wave). It is composed of inverter bridge, control logic and filter circuit. It is widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.

In short, the low frequency power inverter is an electronic device that converts low voltage (12/24/48V) DC power into 220V AC power. We are in a mobile era, mobile office, mobile communication and mobile leisure. In the mobile state, not only the low-voltage DC power supplied by the battery or battery bank is needed, but also the 220 V AC power which is indispensable in the daily environment. The low frequency inverter charger can meet the demand.

Scope of use of low frequency solar inverter:

1) Use of office equipment (such as computers, fax machines, printers, scanners, etc.);

2) Use of home appliances (such as game consoles, DVDs, stereos, video cameras, electric fans, lighting fixtures, etc.);

3) Or when it is necessary to charge the battery (cell phone, electric shaver, digital camera, video camera, etc.).

# Frequently Asked Questions

Q1:What is a pure sine wave low frequency solar inverter?

A1:The low frequency inverter is a DC/AC converter, which is designed with high-frequency pulse width modulation technology and microcomputer control technology to convert the DC power supply of the battery pack into an AC power supply with stable output voltage and frequency. Moreover, it has high conversion efficiency and strong nonlinear load driving ability.

Q2:What are the application of low frequency inverter charger?

A2:The low frequency inverter is widely used in fire protection, building electrical, power plant, communication, subway, railway, aerospace, power, medical, national defense, energy and other projects and industries to provide all-round, stable and reliable power support.

Q3:What is the difference between low frequency inverter and high frequency inverter?

A3:In case of low power, the cost of low frequency inverter is higher than that of high frequency inverter, and its weight and volume are larger than those of high frequency inverter with the same power. However, the reliability of the low frequency inverter is higher than that of the high frequency inverter, which is not easy to be damaged, and has the ability to carry impact loads.

Q4:How to select the proper low frequency power inverter?

A4:The principle of selecting inverter is to determine according to the electrical characteristics of the load. The resistive load (such as incandescent bulb) uses the modified wave, and the inductive load (such as motor) uses the pure sine wave inverter. The prices of the two inverters vary greatly.

Q5:What are the solar inverters manufactured by Xindun Power?

A5:Off grid inverter, on off grid inverter, low frequency inverter, high frequency inverter, hybrid inverter, single phase and three phase inverter, and solar power system products such as solar controller, battery, solar panel.
