I own a GP8000E. Which cover should I purchase?
Ron 
from Michigan 
March 02, 2011
Answer
The Classic Accessories Large Generator Cover fits very good over the Generac GP8000E portable generator.

Jim: I want to buy a protective cover for my Generac 5623 6500W portable generator (33.5" x 26.5" x 27.5"). Any recommendations for a cover that will fit this model of generator?
John G. Smith 
from Maryland 
February 27, 2011
Answer
The Classic Accessories Large Cover will fit up to 8000 watts. We have tested these covers on all of the Generac GP model generators and other manufacturers.

Note: It is important to not include the wheels when measuring the width as the generator covers are not meant to cover them.

What is the difference between the generac 5747 and the generac 5681 besides the price? Also what is max kw and running kw on both. thanks need answer before ordering.
John Maurer 
from Illinois 
February 19, 2011
Answer
In regards to your question, the XG8000E (5747) is designed mainly for construction site use but can be used in residential applications. The GP8000E (5681) is designed for the homeowner. Both models have the exact same engine and alternator with the only difference being the frame construction and the looks. Both units offer 8,000 watts running and 10,000 watts surge capacity.


A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future.
Note: A certified electrician should be consulted for proper sizing and installation of any generator.

How does this generator start in cold weather with the electric start? What is the difference between OHV engine & Generac's OHVI engine?
Daryl Hammond 
from Ohio 
January 17, 2011
Answer
Portable generators are normally stored inside and the B&S 30471 comes with a float style battery charger which is plugged into the generator when not in use. This allows the generator battery to have a sufficient charge when the generator is needed to start.

An OHV (Overhead Valve) engine is compact designed and generally makes the unit operate quieter. The Generac OHVI (Overhead Valve Industrial) engine is built robustly with premium power and high performance and comes with a fully pressurized oil lubrication system and spin-on filter.
