Permit for off-grid inverter?

[SolarTrap]

I have a question about permits to install an inverter at my house.
I want to put one circuit in my house on an offgrid inverter for backup purpose. I asked an electrician and he told me that this would require a permit.
Is this true? Can someone point me at the official "regulations" ?

Thanks
Markus

This is usually specific to your municipality. Consult their Building Codes Division (or whatever it happens to be called). Typically you'll find a statement like this:

Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system, the installation of which is regulated by code, or to cause any such work to be done, shall first make application to the building official and obtain the required permits.

Thanks for your answer. I had recently a level 2 charger for my EV installed but there were no permits necessary. Why is this different from running an inverter?
