SIP MEDUSA® ISG3303 3kW Digital Inverter Generator

The SIP MEDUSA® ISG3303 3kW Digital Inverter Generator is a low noise petrol generator designed with powerful inverter technology that offers a clean and stable pure sine wave output suitable for a range of electronics, devices and tools, including those susceptible to electrical wave distortion.

An enclosed design reduces operating noise - just 68dB(A)* - compared to traditional open-frame generators, ensuring powerful 230V, 12V and USB performance in noise-sensitive environments including camping, outdoor leisure, off-grid, site use and standby.

For outstanding mobility, it is wheel-mounted with retractable handle and anti-vibration feet, perfect for easy positioning and safe, efficient transportation.

Applications & uses: Suitable for camping and outdoor leisure, motorhomes and off-grid support, light trade and site use or domestic standby.

• POWERFUL 4-STROKE PETROL ENGINE FOR HIGH-PERFORMANCE OUTPUT & RELIABLE CONNECTION: Powered by a 149.8cc 4-stroke petrol engine that provides 3kW of dependable output when needed most. Fitted with an integrated economy control switch for low loads and increased fuel efficiency. Built with a manual recoil pull-start and manual choke for reliable and efficient start-up.
• ROBUST DESIGN ENSURES DEPENDABLE OPERATION IN A WIDE RANGE OF APPLICATIONS: Perfect for providing a reliable power supply in a range of environments, including camping and outdoor leisure (smartphones, tablets, laptops, lighting, portable appliances and multi-device charging), motorhomes and off-grid support (charging multiple items simultaneously, toasters, coffee machines, water pumps and low-power heating), light trade and site use (corded tools (drills, sanders, grinders), LED or halogen lighting, battery chargers and site office equipment) and domestic standby (fridge freezers, TVs, routers, small kitchen appliances e.g. microwaves and kettles, and essential circuits).
• MULTIPLE OUTPUT OPTIONS OFFERING A CLEAN & STABLE POWER OUTPUT SUPPLY: Fitted with 2x 230V (13A), 1x 12V DC and 2x USB output sockets which can be used simultaneously to power devices and equipment. Offering a pure sine wave (THD <3%), this generator provides clean and stable output. Inverter regulation offers added reassurance, particularly with sensitive electronic devices more susceptible to higher distortion.
• ENCLOSED MOBILE DESIGN ENSURES MAXIMUM FLEXIBILITY & PORTABILITY IN ALL ENVIRONMENTS: Wheel-mounted and complete with anti-vibration feet and large retractable handle to make positioning easy and transporting it safe and simple. An enclosed design helps to reduce operating noise to 68dB(A)*, ensuring it offers powerful performance even in noise-sensitive environments.
• ENHANCED PROTECTION FEATURES FOR ADDED PEACE-OF-MIND: Visual low oil alert prompts users to refill the vessel, helping to reduce the risk of lasting damage. Overload protection keeps the generator and connected equipment or devices safe from damage by auto-limiting output and preventing overheating. Forced air cooling enables extended operating time as the core components remain cooler for longer.
