Cummins Onan portable

Onan P2500i

Inverter portable generator, gasoline. Ships to your door — no installation, no permit, no electrician.

2,500W Gasoline Inverter — safe for electronics 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.

Ship weight is 60 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 P2500i

How much is the Cummins Onan P2500i?

$623.75, 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 P2500i run?

It is rated at roughly 2,500 starting watts. In practical terms that covers a refrigerator plus lights, phones, laptops and networking gear, which is the core of getting through a short outage. A portable will not run central air conditioning; that is what a standby unit is for.

What fuel does the P2500i use?

Gasoline. If the unit will sit unused for long stretches, use fuel stabilizer and run it dry before storage - stale gasoline is the single most common reason a portable will not start when it is finally needed.

Can I use the P2500i 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.
