Question True 240v Split Phase 2 x 6000XP

I’m currently setting up a dual EG4 6000XP inverter system for an off-grid installation and had a question regarding the AC output wiring shown in your manual.

On page 27 of the EG4 6000XP manual (section 6.12.1), there is a wiring diagram labeled “3 x 6000XPs 120/240VAC Parallel Diagram.” In this illustration, all inverters are configured as Phase P1, and the L1 and L2 output terminals from each inverter are wired together. However, based on my understanding of split-phase systems, proper 240V operation requires L1 and L2 to be 180° out of phase — typically achieved by setting one inverter to P1 and the other to P2 and wiring only the L1 terminal from each inverter to opposite legs of the load panel.

Could you please confirm:

1. Does the diagram on page 27 actually produce a true 120/240V split-phase output, or is it simply a parallel 120V system powering both legs of a 240V panel with the same phase?

2. If true 240V is needed for loads such as electric dryers or well pumps, what is the correct configuration and wiring method (settings + output terminals to use)?

3. Is there any scenario where tying both inverters’ L1 and L2 terminals together, with both set to P1, is a supported or recommended method for 240V output?

I appreciate any clarification your engineering or documentation team can provide. A detailed explanation — or an updated diagram for 120/240V split-phase output — would be extremely helpful for installers trying to avoid misconfigurations.
