Stanley SG 7500B - Petrol Power Generator - AVR - 7,5 kW - Continuous 7 kW Three-phase

The Stanley SG 7500B power generator is a powerful and versatile device designed to provide reliable power in a wide range of situations. This model is ideal for both domestic use and more demanding applications, thanks to its advanced technical features and the 7.5 kW of power it delivers. The generator is equipped with a petrol engine with a large displacement, which provides maximum power to support various types of equipment. The inclusion of the AVR (Automatic Voltage Regulator) ensures a stable and constant energy supply, protecting connected devices from power surges.

Another unique feature of the Stanley SG 7500B is its wheeled design, which makes it much easier to transport and manoeuvre. This makes it particularly useful in settings where the unit needs to be moved frequently, such as construction sites or outdoor events. Additionally, the strong and robust design ensures a long service life, even under demanding operating conditions.

Distinctive features of the Stanley SG 7500B generator:

• 458 cm3 large-displacement petrol engine: ensures high power and stable performance.
• 7.5 kW maximum power: supports a wide range of electrical equipment.
• AVR (Automatic Voltage Regulator): maintains a constant output voltage, protecting connected devices.
• Wheeled design: facilitates transportation and use in various settings.

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 power rating* in LTP emergency service: 7.5 kW

Maximum single-phase power* in LTP emergency service: 3.3 kW

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

Effective three-phase power* in continuous variable duty PRP: 7 kW

Single-phase* effective power in continuous variable duty PRP: 3 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 grommets that secure the alternator to the 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.
