The power frequency inverter is a kind of DC/AC & AC/DC converter, using high-frequency pulse width modulation technology and microcomputer control technology design, to convert the DC power supply of the battery pack into the output voltage and frequency stable AC power supply. More people also call it a “low-frequency inverter”.
The power frequency inverter has a high conversion efficiency (up to more than 85% under full load). At the same time, it has very strong nonlinear load-driving capability. The inverter power supply can also detect and monitor the input voltage, current, and output voltage and current, to realize the function of guard-free maintenance.
Power frequency inverter has many application areas, for now, it’s widely used in solar systems as an inverter off grid. For example, the solar system needs to convert the DC power of the solar panels into an AC power supply for household appliances, then you need to use the inverter. In addition to converting the DC power into AC power, our inverter off-grid has its own mains charging function, assuming that there is a need to charge the battery without using the solar system, then you can use the mains power to charge the battery through the low-frequency inverter, that is, the AC voltage is converted into DC voltage. Generally speaking, the input voltage is changed according to the needs of practical applications, which is necessary to use the inverter.
The power frequency inverter produced by Huayite mainly includes two types
1. Inverter Off Grid
2. Inverter with built-in MPPT charging controller integrated machine
If using an inverter in a solar system, an MPPT charge controller is an essential part of the solar energy conversation, then an inverter with a built-in MPPT controller is a good choice for end users.
Features of low-frequency inverter
The low-frequency inverter is designed based on the traditional analog circuit principle, the internal power devices (such as transformers, inductors, capacitors, etc.) are larger. Generally, there is low noise when the load is large, and the reliability and stability are much stronger than the high-frequency inverter. Because the transformer of the power frequency inverter isolates the mains power from the load, in harsh environments, the power frequency machine provides more safe and reliable protection than the high-frequency machine, therefore, for industrial, inductive home appliances loading, island power generation, and other applications, the low-frequency inverter is a better choice.
