Güde GSE 4701 RS Petrol Generator - 3,600 W AVR
Güde GSE 4701 RS Petrol Generator
The Güde GSE 4701 RS is a 4-stroke petrol generator with a 224 cm³, 5.5 kW OHV engine, 3,600 W rated output, synchronous generator with AVR automatic voltage regulation, recoil start, 15 L fuel tank and up to 13 hours of runtime at 50% load. Manufactured by Güde GmbH & Co. KG, Wolpertshausen (Germany), founded in 1979. Distributed in Italy by Krollit, an official Güde distributor since 2007.
Warning: this generator must not be used to power electronically sensitive devices such as laptops, smartphones or audio systems. A synchronous generator with AVR is not equivalent to an inverter generator: the waveform quality is not suitable for devices with modern switching power supplies.

Who uses the GSE 4701 RS and for what
Krollit customers choose the GSE 4701 RS when the power of the 3701 RS model (2,800 W rated) is not sufficient. With 3,600 W rated output and 14 A current, it powers more demanding loads in three main settings: construction sites with several tools operating at the same time (200 L concrete mixer plus angle grinder plus lighting); farms requiring 2–2.5 kW centrifugal pumps for large-scale irrigation; and trade fair stands or markets with several resistive appliances connected (refrigerated counters, resistance heaters, fluorescent lighting). Its 3,200 W continuous output provides a significant operating margin over the 2,500 W of the lower model.
Who the GSE 4701 RS is for
|
Profile
|
Suitability
|
Reason
|
|
Construction or roadwork site with multiple tools in simultaneous use
|
Suitable
|
3,200 W continuous output allows a 200 L concrete mixer (typically 1,800 W) and a 1,200 W angle grinder to run at the same time, with 200 W of remaining margin.
|
|
Farm with 2–2.5 kW centrifugal pumps
|
Suitable
|
The 5.5 kW / 7.5 hp engine handles the starting currents of high-flow irrigation pumps without triggering the overload protection.
|
|
Event organiser with combined resistive loads above 2,500 W
|
Suitable
|
The 3,600 W rated output can power combinations of resistive loads (heaters, lighting, commercial refrigerators) that the 2,800 W model cannot handle.
|
|
User needing to power laptops, smartphones or digital audio equipment
|
Not suitable
|
The synchronous generator with AVR does not produce a sine wave of sufficient quality for modern switching power supplies. An inverter generator is required for these applications.
|
|
Use indoors without adequate ventilation
|
Not suitable
|
Internal combustion engine: CO emissions are incompatible with confined spaces. Use only outdoors or in adequately ventilated areas.
|
Not suitable for: electronically sensitive equipment (laptops, smartphones, audio systems, medical instruments, UPS); indoor use; applications requiring frequency stability within ±0.5 Hz.

Professional applications
Construction site with multiple loads
With 3,600 W rated output and 14 A across two 230 V sockets, the GSE 4701 RS can power a 200 L concrete mixer (about 1,800 W) and a 1,200 W angle grinder at the same time while remaining within the 3,200 W continuous rating. The 200 W margin allows a third light tool (drill or small grinder) to be started in sequence without overloading the generator.
Agricultural irrigation with high-flow pumps
The 5.5 kW / 7.5 hp engine handles starting currents up to 3–4 times the rated current of centrifugal irrigation pumps with a flow rate of 60–100 m³/h, which the 4.2 kW engine of the GSE 3701 RS cannot always sustain. The 15 L tank provides 13 hours of operation at 50% load, covering a full evening irrigation shift.

Frequently asked questions
What is the practical difference between the GSE 4701 RS and the GSE 3701 RS, and when should you choose the higher model?
The main difference is power: 3,600 W rated and 3,200 W continuous versus 2,800 W / 2,500 W. The GSE 4701 RS can power a 200 L concrete mixer (about 1,800 W) and a 1,200 W angle grinder at the same time, a combination that the 3701 RS cannot sustain continuously.
The GSE 3701 RS remains the more economical choice for sites using only one heavy tool at a time or for agricultural applications with pumps up to 1.5 kW. The GSE 4701 RS is recommended when the total load regularly exceeds 2,500 W or when motor starting currents require higher peak power. Runtime is slightly shorter (13 hours versus 16 hours at 50% load), with a net weight of 47 kg versus 42.2 kg.
Can the GSE 4701 RS power a 200 L concrete mixer and an angle grinder at the same time?
Yes, provided the combined power draw does not exceed the 3,200 W continuous rating. A 200 L concrete mixer typically draws 1,600–1,800 W during operation; a 125 mm angle grinder draws 1,100–1,200 W. The combined 2,800–3,000 W remains within the 3,200 W limit, leaving a 200–400 W safety margin.
It is advisable to start the two tools one after the other rather than simultaneously, to avoid adding their starting currents (which can be 3–5 times the rated current in inductive motors). The overload protection trips automatically if the instantaneous load exceeds the limit and allows the circuit to resume once the load is reduced.
Why is the GSE 4701 RS not suitable for laptops and smartphones?
The synchronous generator with AVR produces 230 V / 50 Hz AC with automatic voltage regulation, but the waveform may exhibit harmonic distortion and frequency variations greater than those tolerated by modern switching power supplies used in laptops, smartphones and digital audio equipment.
Inverter generators convert alternating current to direct current and then invert it again to produce a clean sine wave with THD below 3%, suitable for electronic devices. The GSE 4701 RS is not an inverter generator. For powering sensitive equipment, Güde offers an inverter range in the Krollit catalogue.
What periodic maintenance does the 224 cm³ 4-stroke OHV engine of the GSE 4701 RS require?
Routine maintenance includes: replacing the engine oil (0.6 L, 15W40 or 10W30) every 50 operating hours or at least once a year; cleaning or replacing the air filter every 25 hours; checking and adjusting the spark plug every 100 hours; and replacing the spark plug every 200 hours.
Before each use, check the oil level: the low-oil protection automatically stops the engine if the level falls below the minimum threshold. Unused fuel should be removed from the tank if the generator will not be used for more than 30 days. Original Güde spare parts (air filter, spark plug, oil) are available from the Krollit warehouse in Monteforte Irpino (AV).
Can the GSE 4701 RS be used as backup power during a mains outage?
Yes. It can be used as a backup generator for isolated loads by connecting appliances directly to the panel sockets. However, it must not be connected directly to a household electrical installation without an automatic transfer system (ATS) and the intervention of a qualified electrician, in accordance with CEI 64-8.
Direct connection to the installation without a mains isolation switch is dangerous for utility technicians working on the line. It is not suitable as a UPS source for sensitive equipment for the waveform-quality reasons described above.
How much noise does the GSE 4701 RS produce compared with the GSE 3701 RS?
