It took me a bit of reading replies to understand the issue you
are addressing. If the issue is as simple as not running 240V
loads off of a panel supplied by 120V inverter output, then you
have three approaches. You would expect to run off of either a
pair of inverters set up for 120/240, an inverter with the same
capability (Magnum AE, Radian, XW or Conext SW, etc.), or a single
120V inverter (FX/VFX, SW4024, etc.) with a step-up
autotransformer. If the latter, consider running 120V only to the
main distribution breaker panel, and separately running the 240V
loads, either directly from the autotransformer output (a single
load, such as a well pump) or a small dedicated subpanel (such as
a Homeline or QO 6-12L100S) fed by the autotransformer output.<br>
<br>
Does this help? Did I address your question?<br>

690.10(C) doesn't say no. It says that if you have a single 120V
inverter output connected directly for a 120/240 panel then you
can't put a 240V load in the panel-- in this case you'd either
have L connected to both phases of the panel or I guess you
could just use half the breakers in the panel. For a 240V load
it would just see 0 volts phase to phase, but for a multi-wire
branch circuit with current on both legs you'd potentially
overload your neutral conductor.<br>
<br>
Now when you use either a 240V inverter (or two stacked 120s) or
an autotransformer between the inverter and the panel, 240V
loads are fine since you have two lines 180 degrees out of phase
and voila, 240V. 690.10(C) wouldn't apply to this situation
since your inverter(s) would be supplying 240V (not 120) to your
1P 3W panel.<br>
