Product Details

*Low frequency off grid solar inverter 48V 220V 6000W peak 18000w hybrid pure sine power inverter with UPS charge function

*The hybrid pure sine power inverter is a DC/AC converter, 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. It has high conversion efficiency (up to more than 90% under full load). At the same time, it has strong nonlinear load driving ability. The inverter power supply can also detect and monitor the input voltage, current and output voltage and current, so as to realize the function of free maintenance.
It can be used on imported electrical appliances that require AC110V, such as ships, heavy trucks, industrial equipment, air conditioners, televisions, radios, refrigerators, washing machines, computers, and power tools.

Performance comparison of low frequency power inverter and high frequency inverter:
1. In terms of reliability, low frequency inverters are better than high frequency inverters. car power frequency inverters use thyristor (SCR) rectifiers. After more than half a century of development and innovation, this technology has become very mature. The current impulse capability is very strong. Since SCR is a semi-controlled device, there will be no faults such as shoot-through and false triggering. In contrast, although the IGBT high-frequency rectifier used in the high-frequency inverter has a high switching frequency, the IGBT has a strict voltage and current working area during operation, and the impact resistance is low. Therefore, in terms of overall reliability, IGBT rectifiers are lower than SCR rectifiers.
2. In terms of environmental adaptability, high-frequency inverters are better than lowl-frequency inverters. The operation of the UPS is controlled by means of a software program. Therefore, the volume and weight are significantly reduced, the noise is also small, and the impact on space and environment is small, so it is more suitable for office places with less stringent reliability requirements.
3. In terms of the requirements of the load on the neutral ground voltage, the low frequency inverter is better than the high frequency inverter. Such a structure inevitably causes the rectifier and inverter to couple high-frequency harmonics on the zero line, raising the zero-ground voltage, causing the zero-ground voltage at the load end to rise. 1V site requirements. In addition, when the mains and generator are switched, the high-frequency inverter often has to be switched to bypass work due to the lack of neutral line, which may cause a major failure of load flashing under certain working conditions.
