Low Frequency Off grid Inverter
The SIF series products are mainly made of power electronic components rather than software, resulting in high weight, stability, and durability. The SIF series is equipped with a built-in transformer, which stabilizes the output voltage and can reach a peak power of up to 3 times. It has strong load capacity and strong resistance to current surges. Very suitable for single-phase power environments such as unstable electricity, households, schools, hospitals, shops, farms, factories, etc. And adapt to loads with high instantaneous power, such as water pumps, presses, stamping machines, pumping machines, compressors, and hydraulic presses.
- Fast Delievery
- Quality Assurance
