Güde Power Generator | Petrol, Inverter, and Diesel

Frequently Asked Questions

What's the difference between an inverter generator and a traditional generator?

The inverter generator (such as the Güde ISG 1200-1 Q) converts current into a pure sine wave with less than 3% harmonic distortion. This protects PCs, measuring instruments, and battery chargers from power surges. A traditional generator produces less stable current, which is sufficient for power tools and lighting but not for sensitive electronics.

How many Watts are needed to power a construction site?

It depends on the tools. A drill press draws 500–1,500W, an angle grinder 800–2,000W, and a compressor 1,500–3,000W. For a single tool under 1,000W, the GSE 951 (€142, 720W) is sufficient. For multiple tools used alternately or loads above 3 kW, the GSE 5501 DSG diesel (€1,330, 5,000W) with a 400V three-phase output is recommended.

How much fuel does a Güde diesel generator consume?

Yes. A domestic refrigerator draws 100–200W under normal operation and 600–800W at startup. The ISG 1200-1 Q can handle peaks up to 1,200W. The ECO function automatically adjusts the engine speed to the load, reducing consumption and noise when the compressor is off. Run time with light load: over 6 hours with 3 liters of petrol.

Can the Güde ISG 1200-1 Q inverter generator power a refrigerator?

Can I use a gasoline generator indoors?

No. All internal combustion generators produce carbon monoxide (CO), an odorless and lethal gas. They must only be used outdoors or in environments with full natural ventilation. Position the generator at least 3 meters away from doors and windows, with the exhaust pointed away from the work area.

Güde GSE 951 Gasoline Generator

The GSE 951 (€142) is the entry-level model with a 63 cc, 1 kW 2-stroke engine. Continuous power 650W, peak 720W. 3.8-liter tank for 7.5 hours of runtime at 50% load. Weight 16 kg with integrated handle. One 230V/50Hz 4A socket. Suitable for low-power tools, construction site lighting, and occasional uses where off-grid power is needed.

Güde ISG 1200-1 Q Inverter Generator

The ISG 1200-1 Q (€249) produces pure sine wave power with inverter technology and harmonic distortion below 3%. Continuous power 1,000W, peak 1,200W. 1.3 kW 4-stroke engine with ECO function that adjusts RPM to the load. 3-liter tank, 4.8 hours runtime. Weight 13 kg with LED display. One 230V socket and 2 USB ports. Stabilized current protects sensitive electronics: PCs, measuring instruments, battery chargers.

Güde GSE 5501 DSG Diesel Generator

The GSE 5501 DSG (€1,330) is the model for continuous use in workshops and construction sites. 418 cc, 6.5 kW / 8.8 HP 4-stroke diesel engine. Continuous power 3,300W on 230V (2 sockets), up to 5,000W on 400V three-phase (1 socket). 12.5-liter tank, 7.3 hours runtime, consumption 1.5 l/h. Electric start with included battery. AVR regulation, low oil and overload protection. Weight 141 kg with wheels for mobility. Soundproofed body for enclosed workplaces like workshops and warehouses where noise is a critical factor.

Gasoline, Inverter, or Diesel: Which to Choose

The gasoline GSE 951 is cheaper and weighs 16 kg — for sporadic uses under 650W. The ISG 1200-1 Q inverter is the choice for sensitive electronics and portability (13 kg). The GSE 5501 DSG diesel is for loads above 3 kW or daily use: diesel is cheaper per hour of operation. To power work equipment on site, check the maximum power consumption in Watts before purchasing.
