Selection depends on your total peak load. A 7kw unit is typically sufficient for light commercial use or small office backups. A 20kw unit is designed for industrial workshops or agricultural processing where multiple heavy appliances run simultaneously. We recommend calculating your total wattage and adding a 20% safety margin.

3-phase systems provide more stable power for heavy industrial motors and large-scale machinery. They are more efficient at delivering high power loads and are essential for industrial plants that require balanced electrical distribution to prevent equipment wear.

Yes, these units are designed for dual-purpose use. They provide high-current output for welding while simultaneously offering standard AC power for auxiliary tools. This makes them ideal for mobile repair units or remote construction sites.

In humid environments, focus on preventing corrosion and maintaining air filter cleanliness. Regular oil changes and coolant checks are critical. We recommend using high-quality canopy enclosures to protect the engine from environmental debris and moisture.

We combine 20 years of engineering experience with premium components and stringent quality control. Every stage, from R&D to final manufacturing, is overseen by a team of 200 professionals to ensure stable power output and low maintenance requirements.

Yes, our silent and super-silent models utilize advanced sound-attenuating materials and optimized exhaust systems to minimize noise pollution, making them compliant with most urban noise regulations for healthcare and commercial facilities.
