4,500W Gasoline / LP Inverter — safe for electronics Dual fuel Ships free

Inverter generators produce clean power - low total harmonic distortion - which means you can run laptops, routers, modern TVs and variable-speed equipment off it without worrying about what the waveform is doing to them. They are also dramatically quieter than a conventional open-frame set, and they throttle down when the load is light instead of running flat out.

Running gasoline / lp is the practical advantage here. Gasoline degrades in months and is the reason most stored generators will not start. Propane does not degrade at all, so a unit kept on LP is far more likely to fire on the first pull after sitting through a mild year.

Ship weight is 125 lb. Portables cover essentials during an outage: refrigeration, lights, well and sump pumps, phones and networking. They do not run central air conditioning, which in a Texas summer is usually the load that actually matters — if that is your concern, a permanently installed standby unit is the honest answer.

Questions about the P4500idf

How much is the Cummins Onan P4500idf?

$1,146.15, and that is what you pay - there is no installation, no permit and no electrician involved with a portable. It ships to your door.

What will the P4500idf run?

It is rated at roughly 4,500 starting watts. In practical terms that covers a refrigerator, several lights and outlets, a sump or well pump, and either a small window AC or a space heater - not both. A portable will not run central air conditioning; that is what a standby unit is for.

Can the P4500idf run on propane?

Yes. This is a dual-fuel unit running on gasoline / lp. Propane is the practical choice for a generator that sits most of the year: it does not go stale, it does not gum a carburetor, and a 20 lb tank is easy to store and rotate. Gasoline gives slightly higher output when you need it.

Can I use the P4500idf to back-feed my house?

Only through a properly installed transfer switch or an interlock kit. Plugging a generator into a wall outlet - a suicide cord - back-feeds the utility line and can kill a lineman working to restore your power. It is also illegal. If you want the generator to power house circuits, we install a manual transfer switch, and if you are doing that anyway it is worth asking whether a standby unit is the better buy.
