I'd suggest checking your amp and wattage requirements for all devices and utilities first.  Do the math to assign load and circuit requirements.  Don't over extend any single circuit.  Make sure you have proper wire gauge for circuits.  Check AC units for lock rotor draw (during start up).

Use following list for amp vs. wire gauge.

Amps = Watts / 120

15 amps > 14g wire
20 amps > 12g wire
30 amps > 10g wire
40 amps > 8g wire
65 amps > 6g wire

Be careful with your work.  Do the math, have it verified to be sure.
Good luck,

I do not believe you ever size wire for LRA. Typically FLA plus 20% is what I believe.

Although I wasn't specific, the locked rotor wasn't regarding wire size, but rather Inverter and Genset output.  Sorry!
