connect 2 step down transformers to solar inverter

[edgerly779]

I have on/off grid hybrid solar inverters 6.2kw and a 10kw. Can I connect 2 step up/down transformers to 230vac output of inverter in parallel and output of trans are 120/240 split phase, Shoudl double available amps of 1 unit to connect more appliances

What makes you think the inverters will come up in out of phase? What would compel them to do that? What would compel them to stay strictly in phase?

There are transformers that synthesize a neutral. Not long ago I was involved with installing a 2MW device of that sort. Much more realistic than hoping a few inverters do the job.

Using a transformer or two to change voltage does not change the power available.

These transformers synthesize a neutral. take 230 vac 50/60htz and convert to 120/240 split phase. power from inverter is 6.2 kw 230 vac.
