The Mosa GE 3900 is a compact petrol generator with 2 13A 230V sockets. Equipped with automatic voltage regulation (AVR) it is perfect for running voltage sensitive equipment such as laptops etc. Supplied with wheels and a handle, it is easy to transport and perfect for mobile off grid applications.

This handy little generating set produces 3.3kW of single phase power suitable for domestic, hobby and leisure use. A manual recoil start kicks the generator into life producing power whilst even quieter and more efficient than conventional models. The GE 3900 delivers a stable and precise output to feed even sophisticated electronic equipment, sensitive to variations in voltage and frequency. You can therefore safely and easily enjoy all the small comforts of home wherever you are: lights, fans, a coffee machine, laptop computers, radio or TV.

The 15 Litre tank allows a continuous operation of 9 hours.

An “Oil alert” system prevents damage to the engine due to an insufficient quantity of oil in the engine sump. The system automatically shuts the engine down before oil levels fall below a safe limit.
