Intelligent Low Frequency Hybrid Off-Grid Inverter Pure Sine Wave

Full power three phases pure sine wave inverter used for off grid wind and solar system high quality inverter with CE ROSH certification can used as UPS inverter for industry.

Low-frequency inverters have a few advantages compared to higher frequency inverters; namely their peak power capacity and their reliability. Low-frequency power inverters can operate at a peak power level of up to 300% of their nominal power level for several seconds, while high-frequency inverters can operate at 200% of nominal power for a fraction of a second. Low frequency inverters operate using transformers (as opposed to electronic components such as MOSFETs for high frequency inverters). This results in a stronger, sturdier inverter which is less prone to damage.
