1. Consider a generator and a inverter.
2. Generator is producing power at 50 Hz and the inverter is producing power at 50.3 Hz .
3. Both of the sources are supplying a common load.
4. From which source the load will take power first?

Neither source.
Is this homework?

No. Its for gathering knowledge.

 

Plot sin(A) + sin(B)
or look up the identity formula.

 

if It is a synchronous generator, then the torque vector should synchronise it with the inverter, with a small amount of phase lead, provided that it is lower power than the inverter.
If not, it’s not going to go well. . . .

3 is an impossibility. You will have a blown Generator, Invertor or both.

 

Alternatively, if you have an inverter that is specifically designed for that function, such as some of the Victron products, then the inverter will synchronise itself to the generator.
But then, point #2 won't be true.

 

One of the basic tenets of electrical engineering goes like these:
“Thou shall not connect two AC power sources in parallel unless their frequency, voltage AND phase are identical, or thou shall be dammed by screeching wails and balls of fire, and thy soul will perish.”
