Does anyone have schematics for Aims/sungold/signeer 6000w inverters. These companies are non-cooperative when it comes to post sale customer support. I have a couple of ideas that would make the units more user friendly in the solar arena.

I don't have one but someone could trace out a schematic if they had some motivation to do that.
Did you get a sense of its topology by opening it up and looking at it ?
Only time input neutral can be connected is if there is two low freq transformers, essentially being two 120 vac inverters in series. This is why many 240/120v LF split phase hybrid inverters require 240vac generator and will not work with a 120vac only generator.
This limits the 120vac loads to what the inverter transformer is capable of even in ACin support mode but this is usually not a problem as 240vac loads are not limited by transformer in ACin support mode. The ACin connect relay current rating does limit the ACin support mode maximum current from ACin.
