Dual-Fuel Inverter Generator SENJUN SE7500 6.5 kW (Gasoline / LPG)
The SENJUN SE7500 is a dual-fuel inverter generator with a maximum output of 6.5 kW on liquefied petroleum gas (LPG) and 5.5 kW on gasoline. Its rare-earth permanent magnet inverter technology generates a pure sine wave with a total harmonic distortion (THD) of less than 3%, making it safe for sensitive electronics such as UPS systems, medical equipment, and variable frequency drive compressors. The Automatic Voltage Regulator (AVR) maintains 230 V ±2% under varying loads.
Features and Benefits
A noise level of 65 dB and an electric starter make the unit comfortable to operate near residential areas. Transport wheels simplify moving the 48 kg unit.
Features and Benefits
- Dual-fuel system (Gasoline + LPG): switch between fuel sources without stopping the unit—ensuring continuous power supply if one fuel type is exhausted.
- Inverter technology (rare-earth permanent magnet): pure sine wave THD <3%—safe for PCs, NAS servers, medical equipment, and VFD compressors.
- AVR (Automatic Voltage Regulator): maintains 230 V ±2% during variable loads—critical for equipment with narrow voltage tolerances.
- 65 dB noise level: 7–15 dB quieter than conventional gasoline generators—acceptable for operation near residential areas and at night.
- Electric starter: starts without the need for a manual cord pull, including at temperatures down to −5°C.
- 13L tank: at 50% load on gasoline—up to 8–9 hours of autonomy on a single fill.
- 20 mm gas fitting for connecting a standard propane-butane cylinder.
- Wheels included: transport the 48 kg unit without lifting.
- Generator rotation speed of 3120 RPM, engine displacement of 196.2 cm³.
When to choose
- Ideal for private homes or cottages with unstable power supply: the dual-fuel design provides a backup power channel—if you run out of gasoline, simply connect a gas cylinder.
- For construction sites without grid access, temporary retail outlets, and camping with the option for cylinder connection.
- The dual-fuel scheme is especially valuable in winter when propane-butane cylinders are more accessible and cheaper than gasoline in remote areas.
When NOT to choose
- Not intended for sites with a total continuous consumption exceeding 5.5 kW. For industrial needs of 10 kW and above, industrial-grade synchronous generators are required.
Difference from conventional gasoline generators
- The inverter design instead of an AVR transformer provides cleaner voltage and reduces specific fuel consumption by 20–30% at partial load. The dual-fuel source is a unique feature in the sub-7 kW class.
