AC Output connections from 6000xp to sub panel

[Supervstech]

Entering the inverter about 20 feet from the main panel.

Explain what and where you are measuring please.

I am measuring voltage between ground and neutral, and ground an black (open circuit) that were entering my old Growatt inverter before being connected to the inverter.

There is no neutral at that location.

There is no neutral at that location.

The input to the Growatt is a 240v line (black and white) and a ground. The output is the same that I have been using for my sub panel.

I think you mean between white and ground, which would be L2 and ground...
You were using ground for neutral.

That cable doesn't have a neutral.
It only has
Black = L1
White = L2
Bare = ground

I am thinking of black and white as L1 and L2. And the potential of each of these to ground (the bare copper wire) is 120v giveing the total 240 v between L1 and L2.

In this case, you are not running a ground, you are running a neutral.
You STILL need a ground.

There are only three input terminals on the Growat. L1,L2 and ground. Black, white and bare copper.

If it produces 120v and 240v it has to have neutral and ground.

The bare copper comes from the ground bus bar in the main panel where all the grounds for the house circuits meet.

The black and white come from a double pole breaker in the main panel.

You only have 2 hots and a ground.
There is no neutral in that cable.

Yes, Please look at the Growatt SPF 60000T manual online if possible.

That's 6000T

 

[timselectric]

I am familiar with that unit.
It's input is 240v 3-wire single phase.
Two hots and a ground.
No neutral.

Correct, so where does that leave us.

You need to run a new cable.
The 6kxp requires 120v/ 240v 4-wire split-phase for its input.

 

[D. Abineri]

Yes, that is my conclusion too. Red, Black, Neutral and ground. Do you agree with the connections to my sub panel given above, which was my orginal question.
