Anern has 15 years of experience in solar lighting and solar product manufacturing. Anern Industry Group Limited is headquartered in Guangzhou. With a production base of 7,000 square meters, our company has an R&D team of more than 100 people.
Anern has the WSPI series and the SPI series low-frequency solar inverters. The AN-WSPI low-frequency hybrid inverter is the best choice for small household inverters, stores, and other solar energy generation needs. The AN-SPI low-frequency power inverter with UPS function is the first choice for large-scale solar power system sales for industrial, commercial, and ground power stations.
Low-frequency solar inverters can withstand more complex load conditions. They are suitable for mains power unstable or often off, and important equipment that requires backup power. The hybrid inverter with low frequency has high conversion efficiency and strong nonlinear load-driving ability.
Low-Frequency Solar Inverter VS High-Frequency Solar Inverter
Different frequency
The low frequency is 30~300kHz, and the frequency range is 3~30MH.
Different signal
Compared with the low-frequency signal, the high-frequency signal changes very fast and has a mutation. Low-frequency signal changes slowly and the waveform is smooth.
Advantages of both
The advantages of high-frequency inverters are lightweight and small volume, low standby power, and high efficiency. The low-frequency inverter is more durable and has a strong ability to drive impact electrical appliances.
Application:
Low-frequency solar inverters can be used in residential solar power systems to power household equipment such as televisions, refrigerators, washing machines, and air conditioners. With the help of a low-frequency solar inverter, it can provide a powerful guarantee for small-scale solar power generation systems customized projects such as farms and ranches, meeting your power problem at any time. In addition, low-frequency inverters can provide energy in large solar power systems for industrial use such as power stations in areas where utility power is unreliable.
The size of the low frequency solar inverter you need depends on the size of your solar power system and the electrical load you plan to connect to it. A professional installer can help determine the appropriate size of the inverter for your specific needs.
Yes, low frequency solar inverters can be used in grid-tied solar power systems. However, they are more commonly used in off-grid or remote locations where grid-tied systems are not available or practical.
The low frequency inverter uses a low frequency transformer to boost the voltage. It first converts the DC current into low-frequency low-voltage AC, and then boosts it into 220V50Hz AC for the load through the power frequency transformer.
The operating frequency of the low frequency transformer generally refers to the power frequency of 50Hz or 60Hz. The signal changes slowly and the waveform is smooth.
The low-frequency hybrid solar inverter uses high-speed power transistors at the same power frequency to convert direct current into alternating current for the load to use.
The characteristics of low-frequency solar inverters are: simple structure, more stable, can operate at higher peaks, and higher tolerance to industrial loads.
The characteristics of high-frequency inverters are: small size, higher conversion efficiency, and lighter weigh.
Solar inverters are an integral part of solar power systems, and low-frequency inverters can fully meet the needs of various solar power system solutions ranging from home off-grid solar power systems to commercial solar energy storage systems.
The low frequency solar inverter has a simple structure, stable and reliable operation, strong overload capacity, and strong shock resistance. Superior to high-frequency inverters in two areas: peak power capacity and reliability. Low-frequency inverters are designed to handle higher power spikes over longer periods of time than high-frequency inverters.
Whether a low-frequency inverter is better depends on the specific application and requirements. Low-frequency inverters have some advantages over high-frequency inverters.
Advantages of hybrid inverter low frequency:
Better power quality: Low-frequency inverters produce a cleaner sine wave output with less harmonic distortion, which can lead to better power quality and less interference with other electrical devices.
High surge capacity: Low-frequency inverters can handle high surge loads, such as starting up electric motors, more easily than high frequency inverters.
Better reliability: Low-frequency inverters have a simpler and more robust design, which can lead to greater reliability and longer lifespan.
Yes, like any electrical equipment, low frequency solar inverters require regular maintenance to ensure optimal performance and longevity. Regular cleaning, inspection, and testing are recommended to prevent potential issues and extend the lifespan of the equipment.
Off-grid solar power system: Low-frequency hybrid inverters are commonly used in off-grid solar power systems to convert DC power from solar panels into AC power that can be used to power appliances and other electrical devices. The hybrid aspect of these inverters allows for the use of battery backup systems to provide power during periods of low solar input.
Backup power systems: Low-frequency hybrid inverters can be used in backup power systems to provide emergency power during power outages. These low-frequency inverters can be connected to battery banks or other backup power sources to ensure an uninterrupted power supply.
Mobile power solutions: Low-frequency hybrid inverters are often used in mobile power solutions such as RVs, boats, and other vehicles. These inverters can provide reliable power for lighting, appliances, and other devices while on the move.
Industrial and commercial applications: Low-frequency hybrid inverters are also used in a variety of industrial and commercial applications where a reliable and efficient power supply is required. These applications may include remote telecommunications sites, mining operations, and other off-grid installations.
