I was interested in buying the Generac GP17500E. I did my homework and believe it is the one for me. The questions I have are: 1. Can I convert it to propane? 2. How long will a 15lb propane tank last on this generator if I'm not powering the whole house and just the bare necessities? Thank you Ryan

Mike, it appears the GP15000E generac portable has two plugs one for 120/240 30 amp. and one 50 amp 120/240. That being the case, can one install two inlet boxes and two manual transfers switches, one at 30 amps and one at 50 amps, and wire them up that way. Since it is one power source should not be an issue of cycles being different as power is from one source

I have a Generac GP15000E and I'm trying to purchase a cover that fits. Could you recommend one?

I have the GP15000E but plan to purchase a larger automatic standby generator. Currently only have a 30 AMP inlet installed--so not using all power. Can I install a transfer box (100A or 200A) and a 50 AMP inlet box to use the current generator and still use the transfer box when we install the larger automatic generator? If so, what do you recommend?

Hey Jim, I have the GP17500. How do you charge the battery? In the package there is a 12v start cable. Does this hook up to a trickle charger or is some way else to charge the batt when not in use? Thank you, Anthony Norcia

Ref: Generac Model 5735 We have a 200 AMP service and would like to use the 100 AMP manual transfer switch. Does the 100 AMP switch work the same way as the Kit50-25SB? Is the reason for the price difference the circuit breakers for the 100 AMP switch?

I just received the generator I purchased from you (Generac GP5500 - 5500 Watt Portable Generator) and it comes with a bottle of oil. It does not say on the bottle what type it is. 30 weight or 10w30? Do you know so that it is the proper oil to use for the current temperature. Thanks, Larry

SO IF THERE IS NO ALTERNATOR, DO YOU CHARGE THE BATTERY. WHILE THE UNIT IS RUNNING , OR DO YOU WAIT TILL AFTER YOU HAVE USED THE UNIT?

Hi Mike. I bought a 17.5 kw Generac and want to use it to power the whole house. Is there a way to get more than 50 amps to a transfer switch.? What transfer switch would you choose?

Jim, the GP15000E has one 50 amp 240v outlet. Assuming I can only use one outlet to feed into the connection box on the outside of my house, how much 120v current can I expect to have at my breaker box? How can I maximize the 120V current available for use in my house?

How does this generator start in cold weather with the electric start? What is the difference between OHV engine & Generac's OHVI engine?
