Blackstone BG 4050-X - 3 kW Power Generator with AVR - DC 2.8 kW Single-phase

The Blackstone electric single-phase petrol generator is a product with reduced dimensions which can be easily transported and allows to have power wherever needed.

The generator has a tank with a maximum capacity of 15L and permits the prolonged use of the machine. It has a spark ignition petrol engine with a displacement of 212 cc capable of emitting a power of 7 Hp. The alternator ha an aluminium winding. Moreover it features anti-vibration grommets which reduce the vibrations of the generator when it is being used.

The 4 stroke EURO 5 petrol engine guarantees low emissions during use.

In the control panel there is present a digital voltmeter and an indicator that alerts when the generator has a low oil level.

The Blackstone generator has a sturby protection frame which besides protecting it, also facilitates transport and increasing its stability.

The generator is not designed for energy production, charging or maintaining batteries for the photovoltaic or solar panels systems (or similar); this can seriously damage the generator.

WARNING: all these models of generators that do not belong to the PROFESSIONAL series (considering the product level evaluation used by our website) are not intended for more than 3-4 hours continuous work in order not to reduce the alternator durability as well as that of one of the other machine components due to the unit overheating or wear. As regards a home or intensive use of these generators, it is important to follow the indications mentioned above. In all these conditions, we highly recommend focusing the attention on the purchase of generators renowned as PROFESSIONAL by the product level classification made in our website.

The BG 4050-X generator’s alternator presents an aluminium winding.

Maximum nominal single-phase power * emergency conditions LTP: 2.8KW

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

Maximum nominal single-phase power * in continuous running LTP: 3KW

*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 alternator is fixed to the frame by robust anti-vibration grommets

Focus on the muffler

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

Main features of the engine:

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

Displacement: 212 cc

The engine is equipped with a 15 L steel tank with tap to stop the petrol.

OHV technology

Focus on the air filter.

Extremely complete and rich in functions control panel.

• Led VOLTMETER to see the current voltage output on the outlet
  and the frequency in Hz.
• Switch for engine ignition. When the engine has been started, by pressing this switch the generator will start to deliver power (and the voltmeter display will read 230 volts)
• Thermal protection switch
• 2 16A Schuko power outlet
• Ground discharge
• Oil Warning Indicator Light

Additional features of the generator:

• Space for the control of the fuel level
• Instruction manual
• 15 L tank plug
• Oil tank plug
• Protection frame

As far as the needed power is concerned, we now provide you with an handy chart to help you navigate among consumption, starting coefficients and watt.

The best criteria is to pinpoint first which are the instruments we need to power with the generator and, consequently perform a simple calculation, as explained below, to identify the needed power that the generator need to eject.

Power required = Electric appliance consumption X Breakaway starting coefficient

The starting coefficient is a fundamental characteristic of any instrument which works with electric current because it indicates how much the consumption of the object increases. Therefore, this is needed to concretely determine how many WATT are necessary during the start up operations.

Example: Compressor (1500 Watt ) X Starting coefficient (2) = 3000 Watt Hence you should orientate towards a generator which has a WATT power equal or superior to the result (*)

Check the consumption of the appliance on the instruction and maintenance manual or on the plate attached to the machine.

WARNING: the chart is purely indicative. Thanks to the formula above you can easily calculate the power a generator should deliver to connect and start some specific products and select the model of generator which best suits your needs.

• The generator can be exclusively used to power single electrical appliances (with respect to the produced KW power in relation to the absorption 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 was NOT designed for PROFESSIONAL use, it is therefore apt for occasional use (not frequent). The working sessions must no be over 3-4 continuous hours (which would cause the alternator to overheat and wear, especially in its internal components rotor and stator) If you need a generator for frequent use (for example once a week), the user should look towards another type of generator, specifically intended for a frequent use and precisely a PROFESSIONAL or even INDUSTRIAL quality-level generator (that is not provided with a standard 3000 rpm alternator as this models is, but one which is designed with a professional alternator with low speed; 1500 rpm - with liquid-cooled engine and alternator - which have a level of specific characteristic and price point very different from this model’s);

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.
