I have one answer for all that look at this green answer.
GENERAC Generator.
Keep 20-50 gallons of gas close by and your not paying out thousands every year for taxes, payments and technology that is still in it’s infancy.
All for less than a couple grand.
I maintain both a Solar Array and and Wind Turbine for my Employer. (Both on Grid)
Amplifying others. What you buy today in green Technology will most likely not be repairable due to either Manufacturer/Supplier/Dealers going under or parts no longer made in less than 5 years. We have found that IN BOTH Solar and Wind turbine Systems.
The diesel engine tech that serviced our generator at the credit union I worked for said we love GENERAC because they always break,stay away.
Did you hook up a switching box to your main circuit breaker box? How did it work out? I also have a Generac generator but run it with extension cords as needed. I bought a switching box but never hooked it up, because I'd have to break through a stucco wall. Figured I'd do so if society went bad if TSHTF.
If interested,
This is a pricey yet excellent turbine generator to look at. The smallest is 30 KW that runs best economically on Natural Gas. The company has been around a while. Unlike standard generators these last and run very efficiently.
