Stanley SG 7500B-1 - Petrol Generator - AVR - 7.5 kW - Continuous 7.0 kW Single Phase

The Stanley SG 7500B-1 generator is a powerful and reliable solution for those who need stable power in both domestic and semi-professional applications, with a maximum single-phase capacity of 7.5 kW.

One of its top features is the AVR (Automatic Voltage Regulation) system, which guarantees a constant voltage and protects both the generator and connected devices from surges or current fluctuations.

Thanks to its 458 cm³ engine, the generator is capable of supporting large equipment, offering continuous and robust power to handle even heavy loads.

Designed for convenient use and frequent commuting, it features a design with sturdy wheels and ergonomic handle, making it easy to transport over rough or uneven terrain.

Finally, the capacious 25-litre fuel tank provides extended autonomy, ideal for long periods of use.

Key features of the Stanley SG 7500B - 1:

• Maximum power of 7.5 kW: Suitable for working tools and machinery without mains power.
• 458 cm³ engine: Provides consistent, reliable performance for heavy loads.
• AVR system: Automatically adjusts the voltage for a stable output.
• Wheeled structure: allows safe and easy transport.
• 25 litre tank: provides autonomy for extended work sessions.

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 power generators like this one, belonging to one of the lower product levels of the PROFESSIONAL (reference to the product level rating scale used on this site) must not work for sessions longer than 3–4 hours continuously, in order not to compromise in the medium to long term durability of the alternator and other components due to overheating or 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 opting for generators classified as least as PROFESSIONAL, as listed on the rating scale on this website.

The gen set alternator is constructed with copper windings.

Maximum single-phase power* in LTP emergency service: 7.5 Kw

* in case of emergency, the generator can deliver this power

Single-phase* effective power in continuous variable duty PRP: 7 Kw

* This is the data that must be taken into account as an actual and constant data in the generator’s output (it guarantees it unlimited hours)

The Stanley power generator is equipped with an AVR board: an electronic device that automatically adjusts the output voltage, making it constant when the load changes

It is also equipped with resistant rubber pads that secure the alternator to the frame.

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

The best criterion 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 instructions 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 must only be used to power individual pieces of electrical equipment (within the limits of its power output in KW, in relation to the in-rush absorption of this equipment, which must be less than the power output of the generator);

• The generator can be used to supply power to domestic systems in the event of emergency (lack of power supply service from one's own electricity supplier in the household), only in versions specifically equipped with the ATS automatic start-up device (specially made for this purpose and equipped with the systems for connection to the domestic meter)

• The generator was NOT designed for PROFESSIONAL use, and is therefore only suitable for occasional (non-frequent) use. Operating sessions must not exceed 3-4 continuous hours (which would lead to overheating or wear of the alternator, particularly its stator and rotor components). If a generator is needed for frequent use (e.g. one use per week), the user will have to look for another type of generator, specifically designed for frequent use, and more precisely a PROFESSIONAL or even better an INDUSTRIAL level generator (equipped not with a standard 3000 RPM alternator like this one, but with a professional alternator at low rpm: 1500 rpm - equipped with both liquid-cooled engine and alternator - having a very different level of specifications and price);

The generator is not designed to be installed in photovoltaic or solar panel systems for energy production, nor for recharging or maintenance of batteries of these specific or other electric systems. This use can seriously damage the generator on its internal components (alternator, engine and electrical component). All photovoltaic systems require a generator for INDUSTRIAL use (and not for domestic use like the 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.
