Generac does not recommend a conversion of this type. Such a conversion would also void the warranty.

At this time, Generac does not offer any accessories or conversion kits for its portable generators to run on natural gas. We also do not recommend such conversion, for safety and performance reasons. If you are considering a natural gas generator, we recommend Generac's CorePower automatic home backup generator. This unit runs on your home's existing natural gas fuel supply, is connected directly to your home's electrical system, and turns on and off automatically in the event of a power outage. With an MSRP of $1799, it is comparable in price to many larger portable generators, but offers you the benefits of an automatic home backup solution.

Question

Operating Computer Equipment / Sensitive Electronics

Is the GP5500 recommended at all for the operation of computer type electronic devices? I ran it for one week during this past storm outage and during that time it seems that my adding machine had an issue and stopped working. As I have already purchased it, if it is not recommended for this use, is there some sort of line conditioner that can be placed in line before it is used in my home? As I rent this home, there will be no permanent installation with the exception of a manual transfer switch. Thank you.

The GP Series portable generators have a track record of safely and effectively powering appliances and electronics of all kinds. However, a line conditioner can be placed in line before the power goes to your home. You can select line conditioners from your local electronics wholesaler or retailer.

Functionally both units are the same. The 5939 has been approved for sale in all states except California, which has more strict emissions requirements. The 5737 has been approved for sale in California.

Question

Does GP5000, 5500 and 6500 have the same 389cc OHV engine?

The engine spec in all these three models is 389cc. Are they the same engine powering different output generator or are they slightly modified engines to match the different sized gen. Also, are the engines manufactured oversea as with the whole machine? Thank you!

They are the same engine on all three units. The modifications are made to the alternator to allow for additional output in the larger units.

These engines are manufactured to our specifications by a partner overseas.

Generac does not test the sound level of its portable generators, because there is no industry standard, and any results could be misleading. However, the sound level of this generator is comparable to many portable generators on the market.

Question

Grounding a GP5500 connected to transfer switch

During an outage I would connect my new GP5500 to my home via a transfer switch using the cord with the l14-30 connector. When I wired the transfer switch, I connected the green ground wire to the panel ground bus. Is this sufficient ground or would Generac still recommend a grounding rod be connected?

We recommend consulting with an authorized Generac dealer who can offer advice based upon your specific application. To find one near you, please visit http://www.generac.com/Service/Deal.... Also, Generac portable generators require three-pole manual transfer switches. Additionally, because all Generac portable generators are bonded neutral and most manual transfer switches are floating neutral, you need a transfer switch that also switches the neutrals.

Question

Do not have one

On the GP5500 portable generator is the 2.3.2 120/240 vac 30 amp receptacle (in figure6) in the owner's manual protected with a GFCI breaker in it? If so, with the neutrals that are bonded to the frame, will this create a problem with an electrician who plans to hook up a interlock kit to my home circuit board? If this is not possible and the electrician instead hooks up a transfer switch alongside my circuit panel should such trabsfer switch contain a 3 pole switch that enables neutrals to be switched?

The 30A receptacle is not GFCI protected. However, for this unit to function properly with a manual transfer switch (we always recommend using a manual transfer switch with our portable generators), you will need one that is a 3-pole switch, and one that also switches the neutrals.

Can your GP5500 be converted to either propane or natural gas?

I read a previous question but the answer was not complete. Can the GP5500 be converted to LP and NG without warranty issues? If so, what aftermarket converstion kits are approved to use? The LP3250 is not enough power for my needs.

What's the difference? It would appear only 500 running watts. You can go to the Generac website, www.generac.com and download the spec sheets for both the GP5000 and the GP5500. I think the GP5500 is just a newer model. The GP5000 is no longer featured on Generac's header page for the GP series, but you can search for it and read all the specifications.

Regarding model numbers, according to the spec sheets, the GP5000 is a model #5622-0, and the GP5500 is a model #5939-0.
