Grid tied solar system.

I'm not going to go find the datasheet for that specific model. But I am very familiar with the UPS units typically found in datacenters and no, they generally do not support split phase operation.

Can't answer a specific question for a specific model as you can't be bothered to click on the link (I provided by the way) on a model that you presumably already know about? Why do you even bother to answer?

The model linked does not support split phase operation. The fact that the output connection is only 3 wire (two hots + ground) as opposed to 4 wire (2 hots + neutral + ground) is a good clue.

Is this not a diagram of a split phase system or is it something else?

Here is the data sheet showing "Hardwired Connections"

I'll admit to not understanding the data sheet they show a circled ground on the input and a bare ground on the output. The difference in ground I don't know but apparently N is neutral and something else.

As Beroe mentioned earlier an Autotransformer is required generally for load balancing. You just have to pay extra.

You can indeed use a single ended 120V GTI on a grid connected split phase 120/240 system because the utility grid will provide all of the current on the other hot wire. With a UPS, even a grid interactive UPS, the output goes only to the loads and the utility grid cannot provide the neutral and L2 current needed.
