I purchased the BE 3600 ie for backup power in our greenhouse in the event of a hydro failure. it doesn't happen often, but my wifes plants wouldn't last 10 minutes without heat once temperatures drop below 3,4 degrees down below into freezing. the 3600 model has more than enough capacity to supply two electric heaters if required. I love that the generator shows the percentage of power used plus other features that my Honda 3000 EI doesn't have. against all the advice and instructions from BE and the owner's manual, I have my generator inside my greenhouse with the exhaust plumbed to the outside of the building. I also have a Carbon Monoxide monitor to ensure the air quality inside is safe for entry during operation. After my purchase, I sent BE an email requiring additional information for the purpose that I was using this inverter, to my surprise I got a response email from their great staff the same day with very professional information. . the product is top of the line and their staff exceeds my expectations. I would recommend a BE generator/inverter to all my friends etc. But please never run your generator inside a garage or closed building without proper mitigations!
