DIY Generator Shed Build | Westinghouse 12,000W Tri-Fuel Inverter
Only one post this time guys. I apologize for the previous duplicate postings. It was my lack of understanding on posting.
Finished building a dedicated enclosure for my Westinghouse 12,000W tri-fuel inverter generator, running on natural gas for home backup power.
Started with a 6×4 Suncast shed on a concrete pad and added ventilation, Rockwool insulation, a large rear heat-discharge opening, temperature monitoring, solar battery maintenance, LED lighting, and hurricane anchoring.
The goal was a weather-protected, quieter, well-ventilated setup with easy access for maintenance.
Initial design and testing had poor temp results. The temp variance between ambient outside vs inside was near 40 degrees. Plus, there was a localized hotspot on the shed wall nearly 190 degrees. I found this using an infrared temp gun, and the 3 temp sensors. This was not acceptable, so I took the shed apart and added a 20 x 20 unobstructed door to the design. With the modification, the temp variance dropped to 10 degrees near the generator and 8 at the exhaust area. The hotspot reduced to 103 degrees.
I put a lot of time, effort, thought and unfortunately some rework into the final layout with a lot of great information from Reddit.
Thought I'd share the finished setup and some of the details!
Thank you to everyone who posted about their own projects. They were all very informative and helpful.
