The 9500 lacks a 50 AMP receptacle.
Video gets informative at 2:30:

Do any of the generators the same size have a 50 amp receptacle? I know they have 30 amp.

The Only inverter generator I could find was the Powerhorse

Other generator brands may be out there but they aren't inverter or quiet running that I could find.

House about 8 doors down ran the non inverter 9500 in the past blackout and it was a block shaker.
Our next door neighbors had no clue we were running ours until the sun went down and the house was lit.

I recently picked up this 9500 watt gennie from Lowe’s for about $900. It has a 50A plug

But it’s not an inverter

Picked one of these up at Costco for 449 around the holidays. Works great for the motorhome to keep the batteries topped off and the phones charged.

Is it just assumed or always the case, that if it has a 50 amp plug it is split phase 240v or can you have a 50 amp plug that is just a 50 amp single phase?

All of the home use and construction generators with 50amp receptacles are 240v. I’m sure someone will post some odd ball now but that’s the norm lol.

Something else to keep in mind. 50amps at 240v equals 12,000 watts. Some of these generators have 50amp receptacles but require a parallel kit to get the full wattage. The receptacle will certainly work but may only get you 30ish constant amps.

Like anything just check the specs and see what the start up wattage and constant load wattage is.

The one I posted above, zoom in on the pic and the 50A receptical says 120/240

I have been watching some pretty interesting youtube videos of different ways guys wire up 50 amp RV services.. or if there was such a thing as parallel output on a single phase , so I thought I would just ask...

Most RVs that use 50A service do use a 240V plug but don't have any 120V appliances. Just like your house, they have a panel that has 2 separate 120V sides. Since there aren't any 240V appliances in the RV, it is safe to tie both of the 120V sides together and feed them together from one 120V source. A pigtail adapter like this ties both hot legs together in the adapter.

The 240V generators that you are referring to are single phase (sometimes referred to as split phase). They have two hot legs that are 180 degrees out of phase with each other but because they are exactly 180 degrees out of phase (perfect opposites) they are referred to as single phase. There is also a neutral that you can use along with one of the hot legs to get 120V. I do not know of any generator that produces 120V @ 50A and splits the 50A between the two hot legs on a 4 prong plug. That could actually be pretty dangerous if someone didnt know it was a non-standard configuration and I don't think any company would ever build a generator like that.

Multi phase (like 3 phase 208V) is an entirely different animal.

Thanks, thats exactly the information I was curious and unsure about. I understood that the 240v should have the 120v legs 180 degrees opposite but didn’t know if some cheap or unsophisticated generator could possibly have a 50 amp plug somehow jumping L1 to L2 behind the plug providing some weird Chinese version of an 50 amp 4 prong plug. Sound like it really should not be a concern.

Good description.
In our case one leg hots up half the panel, the other leg hots up the other half.
Runs the house with ease.
