Könner & Söhnen 5500W Dual Fuel Inverter Generator | LPG/Gasoline, Electric Start, CO Sensor | KS 6000iEHS CO

Könner & Söhnen 5500W Dual Fuel Inverter Generator | LPG/Gasoline, Electric Start, CO Sensor | KS 6000iEHS CO

Q: Does it come with the propane hose?

Yes - the propane hose and regulator are included. You can run on propane straight out of the box; just add your own tank.

Q: How much power do I lose on propane?

About 10%. On gasoline it&#39;s 5,500 starting / 5,000 running watts; on propane, roughly 4,950 / 4,500. Gas for maximum power, propane for storage and convenience.

Q: How long does it run?

6.8 hours at 50% load on a full 2.9-gallon tank of gas. On propane, run time depends on your tank size — a standard BBQ tank goes a long way at lighter loads.

Q: Can it back up my house?

It powers essential circuits through a manual transfer switch or interlock — fridge, furnace blower, sump pump, lights, and electronics. It&#39;s not sized to run central AC plus your whole home at once; plan your load.

Q: Will it run in the rain?

It&#39;s IP23M-rated to keep running through rain and spray. Still keep it on dry, level ground, in the open air, away from the house.

Q: Will it run sensitive electronics?

Yes. The pure sine wave inverter (&lt;3% THD) delivers clean, wall-quality power — safe for laptops, TVs, and equipment like CPAP machines.

Q: What's in the box?

Generator, propane hose with regulator, owner&#39;s manual, spark plug wrench, PH2 screwdriver, and an oil funnel. (No oil or gas included — add 10W-30 or 10W-40 before first start; use 87-octane or higher.)

Benefits

GAS OR PROPANE, OUT OF THE BOX: Run on gasoline for full power or propane for storage that never goes stale - the propane hose and regulator are in the box. Switch fuels to suit the job or whatever you can get during an emergency.
REAL POWER, CLEAN POWER: 5,500 starting / 5,000 running watts on gasoline (about 10% less on propane - roughly 4,950 / 4,500), delivered as a pure sine wave at less than 3% THD. Clean enough for laptops, TVs, and a CPAP; strong enough for power tools and a well or sump pump.
PUSH-BUTTON START, HOURS OF RUN TIME: Electric start with recoil backup, plus a 3-in-1 start dial that combines fuel valve, choke, and start in one motion. 6.8 hours at 50% load on a single 2.9-gallon tank of gas — or run off your propane tank for the long haul.
CONVERSATION-QUIET, RAIN-READY: 58 dB at 25% load (23 ft / 7 m) inside a fully enclosed soundproof housing - around the level of a normal conversation. IP23M-rated to keep running through rain and spray.
BUILT-IN CO SAFETY + U.S. SUPPORT: Automatic carbon-monoxide shutoff plus low-oil and overload protection. German-engineered, 3-year limited warranty, and U.S.-based service you can call directly.

Features

The KS 6000iEHS CO runs on gasoline or propane, right out of the box — the propane hose and regulator are included, not sold separately. It pairs a 9 hp dual-fuel K&S engine with a CopperCore copper-wound alternator, pure sine wave output (<3% THD), push-button electric start, and a built-in CO safety shutoff. At 5,000 running watts it carries the essentials through an outage — fridge, furnace blower, sump pump, lights, and every device in the house — and when the gas stations are dark, you switch to the propane tank you already keep for the grill.

Dual Fuel: Gasoline or Propane

Runs on both fuels, and everything you need to do it ships in the box - including the propane hose and regulator. Gasoline gives you full 5,500W starting power; propane runs about 10% lower but stores for years and burns cleaner, which makes it the fuel you want on hand for emergencies. Gas stations close during a blackout. The propane tank in your yard doesn't.

Clean Power (<3% THD)

A microprocessor-controlled inverter holds the output to a clean 120V/60Hz sine wave at less than 3% total harmonic distortion — the same quality of power that comes out of your wall. Under 3% THD is the line where power is safe for sensitive electronics: laptops, flat-screens, game consoles, or medical equipment like a CPAP, without the flicker, buzz, or risk of a rough-power generator.

K&S 223cc Dual-Fuel Engine with CO Safety Shutoff

The proprietary K&S 240i-H1 engine (223cc, 9 hp, single-cylinder four-stroke) is built for long, steady runtime on either fuel and meets current U.S. emissions standards, so it burns cleaner and quieter. An integrated CO sensor watches carbon-monoxide levels around the unit the whole time it runs and shuts the engine down automatically if CO climbs to a dangerous level. It's a backstop — not a license to run indoors.

Eco Mode

Flip on Eco Mode and engine speed drops to match the load instead of running flat-out. At lighter loads that cuts fuel use by up to 50%, stretches your tank, and drops the noise further. Over a multi-day outage, that's the difference between one gas run and three.

3-in-1 Start Dial

One dial handles the fuel valve, the choke, and electric start — no juggling separate controls in the cold or the dark. Turn, press, running. It's the kind of small design decision that separates a generator you can live with from one you fight.

10-in-1 LED Command Panel

One display shows output power, voltage, frequency, fuel level, and total run hours at a glance — plus warning indicators for CO shutoff, CO-sensor fault, low oil, overload, and output status. The panel also carries two 120V 20A outlets, the 120/240V 30A outlet, a 12V automotive socket, and a QC 3.0 USB-C port under a protective cover.

Soundproof Housing

The fully enclosed housing keeps it at 58 dB at 25% load (23 ft / 7 m) - conversation-level, and a different world from the open-frame units that force your neighbors indoors. IP23M-rated, so rain or spray during an outage won't stop it.

CopperCore Brushless Alternator

A brushless permanent-magnet alternator wound with 100% copper — not the cheaper copper-clad aluminum in budget units. Copper runs cooler and holds output steady under sustained heavy loads, exactly what you want when it's carrying your house for hours. Compact, sealed, built to last.

Transport System

Two wheels and a fold-up handle that lifts only when you move it — so one person can roll it from the garage to the driveway and tuck it away without a wrestling match.

**LPG operation reduces generator power by 10%.

*** Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condition of the generator.

ATTENTION! The product is sold without engine oil or gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 87 or higher. t's acceptable to use gasoline with 10% bio-ethanol.

Which Generator Power to Choose?

Very surprised I never heard about this brand.My coworkers and I put together very simple process. All own different brands of generators. We work for service department for a German car manufacturer. We see the quality in this brand. Features. We highly recommend.
Glad we found it . Buy it you won’t regret it.

Matériel conforme au besoin qui démarre au quart de tour après avoir mis l’huile. Courant très stable
L’avantage du gaz c’est le côté pratique et économique et le démarrage facile
Très beau matériel mais prix un peu élevé avec de plus +100€ depuis l’année derniere

Bonjour Alain, merci beaucoup pour votre avis positif ! Nous sommes ravis que le générateur réponde à vos attentes et que vous appréciez sa stabilité et sa facilité d'utilisation. Concernant le prix, nous faisons de notre mieux pour offrir un excellent rapport qualité-prix. N'hésitez pas si vous avez d'autres questions ou besoin d'aide !

Muy buen generador

Der Kauf und die Lieferung waren so, wie man sich das vorstellt.

Thank you for your kind words! We're glad you are satisfied with your purchase and delivery. Enjoy your inverter generator!
