Hello pappy and thank you for your question. I am Designing Woman from The Community.
The GE 10KW Home Standby Generator - Whole House Managed Power estimated fuel supply requirements at half and full load for LP (Liquid Propane) vapor are listed on page 14 of the Installation and Start-Up Manual:http://www.homedepot.com/catalog/pd...
½ load is 35 cubic feet per hour or 86,375 BTU’s per hour
Full load is 65 cubic feet per hour or 163,625 BTU’s per hour
The GE Technical Service folks gave me a quick rule of 2 gallons propane per hour @ full load. For a 1000 gallon tank, this would give 500 hours run time – just under 3 weeks of extremely optimistic and optimal conditions. Contact your propane supplier for the best advice regarding your propane usage requirements.
Best wishes on your project.
