High frequency inverter (parallel)

High-frequency off-grid inverter is a device used to convert DC power to AC power and is widely used in off-grid solar power generation systems. It uses high-frequency switching technology to achieve high efficiency and lightweight design, usually small in size and light in weight. The inverter can effectively increase energy,Conversion efficiency, supports a variety of loads, and has overload, short circuit and overheating protection functions to ensure safe and stable operation of the system. Suitable for remote areas and emergency power supply needs, gradually becoming an important part of green energy solutions

Product Features

  • 1、High efficiency: High-frequency inverters usually have high energy conversion efficiency and can minimize energy loss.

  • 2、Small size and light weight: Due to the use of high-frequency transformers, the size and weight of inverters are usually smaller than low-frequency inverters, making them easier to install and move.

  • 3、Strong starting ability: High-frequency off-grid inverters can start high-power appliances, such as motors and refrigerators, and adapt to load changes.

  • 4、Multiple output waveforms: Many high-frequency inverters provide sine wave output, ensuring compatibility with various electrical appliances and reducing the risk of electrical appliance damage

  • 5、Overload protection: Most high-frequency inverters have built-in overload and short-circuit protection functions to ensure safe system operation.

  • 6、Programmable control: Some high-frequency inverters support configuration through software, and users can adjust parameters as needed.

  • 7、Smart monitoring: Many high-frequency off-grid inverters are equipped with monitoring functions that can display battery status, load conditions and energy production in real time.

  • 8、Strong adaptability: able to adapt to different DC input voltages and suitable for many types of battery systems, including lead-acid batteries and lithium batteries


Application Field

  • 1、Solar power generation system: It is widely used in home or commercial solar photovoltaic systems to convert the DC power generated by solar panels into AC power for use by loads

  • 2、Wind power system: In off-grid wind power, the DC power generated by wind turbines is converted into AC power to meet the power needs of small grids or isolated areas

  • 3、Mobile RVs and Boats: Used for mobile devices such as RVs and yachts to provide reliable AC power and support the use of lighting, home appliances and other equipment

  • 4、Power supply in remote areas: In remote areas without grid access, solar or wind energy is combined to provide stable power supply to local residents

  • 5、Emergency backup power supply: As part of the emergency power supply system, it provides backup power for key equipment (such as refrigerators, lighting fixtures, etc.) during a power outage

  • 6、Agricultural facilities: On farms or greenhouses, off-grid inverters can be used to power irrigation systems, temperature control equipment and other agricultural machinery

  • 7、Communication base station: Provide stable power for communication equipment in remote areas to ensure the continuous operation of communication equipment

  • 8、Small industrial and commercial equipment: used in small factories, shops and other places to support the normal operation of equipment and reduce dependence on traditional power grids
