Hyundai HY3900Si 3.3kW 3300W Petrol Inverter Generator

Hyundai HY3900Si 3.3kW 3300W Petrol Inverter Generator

The Hyundai HY3900Si 3.3kW Petrol Inverter Generator is a compact and portable power solution designed to provide clean, stable electricity wherever mains power isn't available.

Producing a maximum output of 3.3kW / 3300W and a continuous output of 3.0kW / 3000W, the HY3900Si is ideal for caravans, motorhomes, camping, outdoor events, workshops, garages and a wide range of off-grid applications.

Thanks to Hyundai's pure sine wave inverter technology, the HY3900Si provides a stable electrical output suitable for sensitive electronic equipment including laptops, televisions, mobile phones, chargers and other electronic devices.

Powerful 3.3kW Inverter Generator

Powered by a compact 144cc 4-stroke Hyundai petrol engine, the HY3900Si offers an excellent combination of performance and portability.

With up to 3300W maximum output, it provides considerably more power than smaller portable inverter generators, making it suitable for users who need to operate several appliances or devices at the same time.

Pure Sine Wave Power

Unlike many conventional generators, the HY3900Si uses pure sine wave inverter technology to produce clean and stable electrical power.

This makes it particularly well suited to modern electronic equipment and sensitive devices such as:

• Laptops and computers
• Mobile phones and tablets
• Televisions
• Battery chargers
• Caravan and motorhome equipment
• Lighting
• Small appliances
• Electronic equipment

ECO Mode

The built-in ECO Mode automatically reduces engine speed when full power isn't required.

This helps to reduce fuel consumption and operating noise, while extending running time between refuelling stops.

Ideal for Caravans & Motorhomes

With 3000W continuous output, the HY3900Si is an excellent choice for larger caravans and motorhomes where a smaller 1kW or 2kW generator may not provide enough power.

It can provide portable power for equipment such as fridges, lighting, televisions and device chargers, subject to the total electrical load remaining within the generator's rated output.

Compact & Portable

Despite its impressive output, the HY3900Si weighs just 21.15kg, making it relatively easy to transport, position and store.

Its compact enclosed design also makes it particularly suitable for leisure and mobile applications where space is limited.

Why Choose the Hyundai HY3900Si?

The Hyundai HY3900Si 3300W Inverter Generator is an excellent choice when you need more power than a typical compact 2kW generator but still want something that's portable and easy to transport.

Combining 3.3kW peak power, pure sine wave output, ECO mode and a compact 21.15kg design, it's particularly well suited to caravans, motorhomes, camping, outdoor events and other situations where reliable portable electricity is required.

Important: Always check the starting and running wattage requirements of the equipment you intend to power before connecting it to the generator. The combined electrical load must remain within the generator's rated output.
