Mosa GE 3900 Generator

The Mosa GE 3900 petrol generator can deliver a maximum single-phase power of 3.3 kW.

Powered by a 4-stroke GK 225 petrol engine 223 cc of 7.5 Hp. Large fuel tank, holding up to 15 L fuel.

It is very easy to transport thanks to its wheels and folding handle, and allows you to have power available wherever needed. (The handle and the wheels are standardly equipped and they can be assembled by any user) This generator can also be used in the portable, non-trolley-mounted version, just do not attach the wheels and handle.

Equipped with AVR board: the current generator has an electronic card that automatically adjusts the output voltage, keeping it constant under varying load conditions

Equipped with an automatic stop for overloads and low oil level.

On the control panel, in addition to the sockets, there is also a digital screen where the voltage, frequency and hours of use can be checked.

CAUTION: All power generators like this, belonging to one of the lowest levels of the PROFESSIONAL level products (refer to the product level rating scale used on this site) should not work for longer sessions of 3-4 hours continuously, in order to not to compromise in the medium-long term durability of the alternator and other components due to overheating or to wear. The same problem would present itself if these products were to be used daily or at least frequently. In all these cases we recommend to opt for generators classified as least as PROFESSIONAL, as listed on the rating scale on this website.

Alternator and power output

The generator alternator has a copper winding.

Maximum single-phase nominal power* emergency conditions LTP: 3.3 KW

* in case of an emergency the generator can reach this maximum power

Nominal power* in continuous running PRP: 3.0 KW

*This is the data that should be taken into consideration as an effective and constant data for the generator output (it guarantees the product an infinite duration)

The generator is equipped with AVR board: an electric device which automatically regulates the output of tension, making it constant as the load changes.

Focus on the sturdy anti-vibration grommets that ensure the alternator to the frame.

Engine technical specifications

Engine features:

Model: GK 225

Type: 4 stroke, single-cylinder, air-cooled, OHV, horizontal shaft

Displacement: 223 cc

Power: 7.5 HP

Fuel: petrol

Tank: 15 L

Ignition mode: Recoil starter

Focus on the engine air filter

Focus on the recoil start

OHV technology

The generator is provided with 15 L metal tank with fuel shut off valve.

Focus on the engine air filter.

The generator AVR card (used to regulate the output voltage) allows to automatically regulate the gas rate and it is responsible for the engine acceleration in case of sudden changes in load.

OHV technology

Control panel

The control panel of the power generator is complete and full of functions.

  • 2 Schuko power outlets AC 230V PI44 16A
  • Grounding discharge
  • Power switch
  • DC breaker
  • Charger socket
  • Contact breaker
  • Voltmeter-Frequency-Counter

Additional details

Additional features include:

Large tank of 15 L capacity This makes sure that the generator can guarantee an high autonomy.

This tank is designed in metal and is equipped with an external diesel control system.

Handle that can be closed to ease transport

Rear wheels for easy transport

Front rubber pads

Focus on the muffler

Oil tank plug

How To Select The Correct Power Rating Of The Generator

As regards the power needed referring to the use you will make of your generator, here below an extremely useful table to guide you among consumptions, starting coefficient and watt. Firstly, the highest-quality method is to identify which are the electric appliances we need to power with the generator and then perform a simple calculation to identify the necessary power that the generator must supply, as explained below.

Power required = Electric appliance consumption X Breakaway starting coefficient

The starting coefficient represents a fundamental feature for all the electric equipment as it indicates how much the consumption of the electric appliance increases. Therefore, it allows to concretely determine how many WATTs are necessary during the start-up operations.

Example: Air compressor ( 1500 Watt ) X Starting coefficient ( 2 ) = 3000 Watt

Hence, it is important to address your choice on a generator featuring equal or higher WATT-rated electric power than the result obtained from the calculation made.

( * ) Check the consumption of the electric appliance on the operator’s use and maintenance manual or on the plate attached to the machine.

WARNING! Purely indicative table. Thanks to the formula indicated above you can easily calculate the electric power that the generator has to supply in order and connect to the generator specific electric appliances and select the model of generator which best suits your needs.

Electric Generators – Warnings & Range Of Application

  • The generator can only be used to power individual electrical equipment (respecting the rated power in KW produced by the generator in relation to the absorption of the appliances during the starting phase that must be lower than the power supplied by the generator).

  • The generator can be used to power household device in emergency conditions (no current service provided by the domestic household), exclusively on the models that are specifically provided with ATS (Automatic Transfer Switch) device (specifically designed for this purpose and provided with connecting systems to your household electrical power).
  • The generator is NOT intended for PROFESSIONAL use. It means that it is exclusively designed for occasional use (infrequent use of the unit). The working hours must not exceed 3-4 of continuous running (which may lead to the alternator overheating or wear, especially to its internal components: alternator stator and rotor). Whether you’re looking for a generator for intensive use (once a week, for instance), the operator should address the choice to a different type generator specifically designed for a more intensive use. Indeed, you should focus the attention on PROFESSIONAL or even INDUSTRIAL quality-level generator (that is not provided with standard 3000 rev/min alternator as this specific model, but it is designed with professional alternator with low speed: 1500 rev/min – with liquid-cooled engine and alternator – in this case you’ll see that the unit specifications and price are much different from this model).

The generator is not designed to be installed in photovoltaic or solar energy systems for energy production nor for the recharging or maintenance of batteries of these specific or other electric systems. Indeed, it may damage seriously the generator on its internal components (alternator, engine and electrical component). Each photovoltaic system requires a generator for INDUSTRIAL use (not for domestic use as this present model), specifically designed and manufactured for this purpose. WE DO NOT PROVIDE WARRANTY on generators connected to photovoltaic systems, as this entails an IMPROPER USE OF THE UNIT.
