Whatever you do, have a pro install it and make sure it confirms to electrical code. Too many 'tards out there "backfeeding" their generators onto the grid which kills linesmen. In fact, it is illegal to backfeed in most places and they will send your arse to jail if they catch you. Dont be that guy (not saying you are that guy).
Have an electrician do it right with a transfer switch/interlock.

That’s mostly true, but the man says a Kw= KWA and that not correct !

The power factor from a utility is generally 0.9 and above for residences. I'll pull this good quote I found:
The power factor is determined by a load, not the utility. Utilities have a power factor window they want to maintain for a myriad of reasons. The closer the power factor is to 1, the happier the utility will be.
Purely resistive loads will have a power factor of 1. Inductive loads like traditional wound motors can see power factors as low as .8. Most switching electronics will have power factors between .95 and 1 with most being in the .98 to .99 range.

In most states it is OK to backfeed and many states make it required to allow you to backfeed. The issue is everyone has to be aware (the utility, owner, line workers, etc.) so that the metering and switches are designed for it. The introduction of widespread solar has made this practically a requirement.

Exactly. So for residential applications, kW = kVA. The difference is negligible.
