Gas (LPG) Generators

Buy Gas & Dual Fuel Generators – Clean, Quiet Power with Fuel That Stores for Years

Gas generators and dual fuel generators are the right choice for anyone looking for a particularly clean, quiet power source with long-term fuel storage, whether mobile or stationary. They burn liquefied petroleum gas (LPG / propane), natural gas or – in dual fuel mode – petrol as an alternative, with significantly lower emissions than conventional combustion engines.

At Kipor.org you'll find gas and dual fuel generators from our own brand FME (FME 12000GA/GG14 with 12 kW on LPG and FME DF-8000 with 7.5 kW dual fuel) as well as the Genergy Natura range, which we distribute exclusively in the DACH region. Every model is technically checked and suited to the European market.

Honest Advice: When Gas or Dual Fuel Is the Right Choice – and When It Isn't

Gas generators have real advantages, but also clear limits. At Kipor.org we'll tell you honestly when the technology is worth it:

A gas or dual fuel generator is the right choice if:

– You want to keep a backup power reserve for many years – LPG stays ready to use practically indefinitely.
– You have a natural gas line at your house and can connect it for an unlimited fuel supply.
– Clean combustion and low emissions matter to you.
– You want maximum fuel flexibility (dual fuel – both gas and petrol).
– You want to run the generator indoors or in a cellar (with a professionally installed exhaust system) – gas burns much more cleanly than petrol/diesel.

A gas generator is NOT the right choice if:

– You need maximum power per litre of fuel – LPG has around 10–15% lower energy density than petrol, which affects the generator's output.
– You want to use the generator regularly in severe cold spells below -10 °C – LPG vaporises less well at very low temperatures, so diesel or petrol is more reliable here.
– You're looking for a purely professional continuous-duty solution with many operating hours – a conventional diesel generator is more economical for that.
– You don't have a safe place to store gas cylinders or tanks.

We're happy to work out which technology suits your particular application in a short conversation – our advice is brand-independent.

What Gas and Dual Fuel Generators Are the Right Choice For

Home backup power with a natural gas line: if you already have a mains gas supply, a gas generator with ATS is the most elegant backup power solution – an unlimited fuel supply with no jerry cans, no storage issues and no refuelling.

Long-term backup power reserve: for anyone who runs the unit perhaps once a year as a test and otherwise keeps it in the cellar as insurance – LPG can be stored for years, petrol for only 3–6 months.

Hybrid PV systems: as a backup generator for solar PV with battery storage – when the system needs reserves after several cloudy days. Gas burns cleanly and fits well with the "green" self-sufficiency approach.

Food trucks & mobile catering: if you already cook with propane, you can run a gas generator from the same tank – only one fuel to manage and a lower fire load.

Motorhomes & camping (larger setups): Genergy Natura and comparable models are interesting for motorhome owners who have LPG on board and only want to carry one fuel.

Sensitive indoor installation: with a professionally installed exhaust system, gas generators are better suited to cellar installation than petrol or diesel units – the exhaust contains significantly fewer pollutants.

Pure Gas or Dual Fuel – What's the Difference?

Pure gas generators (such as the FME 12000GA/GG14) are specially optimised for running on LPG or natural gas. They often deliver more power on gas than typical dual fuel models, because the entire combustion process is designed for gas. Ideal for stationary home backup power with a natural gas connection or fixed propane tanks.

Dual fuel generators (such as the FME DF-8000) offer maximum flexibility: they can run on either gas or petrol – you change over using a switch on the unit. That's handy when your gas reserve runs out and you need to switch to the petrol can at short notice, or vice versa. Output on petrol is usually slightly higher than on gas, which is physically normal.

Genergy Natura is a particularly interesting option: it combines propane or petrol operation in a compact, lightweight generator, making it a good all-rounder for motorhomes, food trucks and home backup power.

Power Classes and Their Typical Applications

2–5 kW: Compact dual fuel models for camping, food trucks, motorhomes and smaller backup power applications. Light and easy to transport.

5–8 kW: The best-selling class for home and farm backup power. Powers refrigeration, lighting, heating controls, a water pump and smaller tools. Models such as the FME DF-8000 (7.5 kW dual fuel) hit exactly this size.

8–12 kW: Full home backup power including the heat pump, as well as smaller businesses. The FME 12000GA/GG14 with 12 kW on gas covers this class – ideal as stationary backup power with an ATS connection.

Over 12 kW: For larger stationary installations, please contact us directly – gas generators of this size are usually project-specific and configured to order.

Key Buying Criteria for Gas and Dual Fuel Generators

LPG or natural gas? LPG (propane/butane) is stored in cylinders or tanks – flexible and usable anywhere. Natural gas (methane) is connected via your home's gas line – stationary use only, but with an unlimited fuel supply. Some models can handle both, often with a different jet setting.

Output on gas vs. petrol (dual fuel): Rated power on gas is typically 10–15% lower than on petrol, because LPG has a lower energy density. Always allow for this difference when sizing, especially if you mainly plan to run the generator on gas.

Connection & safety: Connection to LPG cylinders or a natural gas line must be carried out properly by a qualified gas engineer – with approved pressure regulators, hoses and safety valves. We supply the generator; the on-site connection is a job for a qualified installer.

ATS connection: If you're planning home backup power, look for an ATS connection – so the generator starts automatically and takes over when there's a power cut.

Noise insulation: Gas generators tend to be quieter than diesel but louder than pure inverter solutions. If you're setting up in a residential area, an additional soundproof enclosure is worthwhile.

Cold-weather performance: Pure LPG (with a butane content) vaporises less well at very low temperatures. For year-round backup power reserves in cold regions, we recommend propane-dominant mixtures or a natural gas connection.

FAQ – Frequently Asked Questions About Gas and Dual Fuel Generators

How long does a gas generator run on an 11 kg propane cylinder?

An 11 kg propane cylinder holds around 21 litres of liquefied gas. A 5 kW gas generator uses roughly 1.5 kg of gas per hour at half load and around 2.5 kg per hour at full load. So, depending on the load, an 11 kg cylinder lasts for around 4–7 hours of operation. Larger generators (e.g. 12 kW) use it up correspondingly faster – for these we recommend connecting to a larger propane tank installation or a natural gas line.

Which is better: LPG, natural gas or dual fuel?

That depends on your situation. LPG is flexible and available everywhere (filling stations, DIY stores, heating gas suppliers) – ideal for mobile applications and backup power without a fixed connection. Natural gas is the most economical solution if you already have a gas line to your home – unlimited supply, no storage. Dual fuel offers maximum flexibility, though usually with slightly lower output on gas than a pure gas model. We're happy to advise you on the option that suits your home or application.

Can I use camping gas or heating gas?

Yes, as long as it's propane, butane or a standard commercial mixture of the kind sold in ordinary gas cylinders (e.g. 5 kg or 11 kg cylinders). Important: the pressure regulator must match the generator (typically 30 mbar or 50 mbar depending on the model). Our operating instructions give the exact specifications.

Do I lose power if I run on gas instead of petrol?

Yes – with dual fuel models, rated power on gas is typically 10–15% lower than on petrol. That's due to the lower energy density of LPG. Pure gas generators, on the other hand, are fully optimised for gas operation and deliver their full rated output on gas.
