The SGS 4000W Inverter Generator is a powerful and reliable portable power solution, designed to deliver clean and stable electricity for both domestic and professional use. Ideal for powering tools, appliances, and sensitive electronics, it combines high performance with advanced protection features for dependable operation.

Powered by a robust 174cc 4-stroke OHV engine, this generator delivers a peak output of 4000W and a rated continuous output of 3800W, ensuring consistent performance for a wide range of applications.

Important Guidance

To select the correct generator, calculate your total running wattage and the highest starting wattage of your appliances. Choose a generator that exceeds both values, and it is recommended to add an additional 20% capacity to avoid overloading.

Overloading can damage the generator and may invalidate the warranty. Always follow the manufacturer’s guidelines and refer to SGS Generator Buying Guides for further information
