Grid setpoint creates one negative phase

So I have a setpoint of 50W.

For some reason this creates a situation where two phases are pulling energy from the grid, and one phase is pushing it back up to the grid. Thus creating a summary of about 50W.

Why does this happen? Why not just divide the 50W evenly between the three phases instead of having two positive and one negative?

This seems like an odd behaviour and I would love to understand why this is the way it works.

Thanks in advance!

@Fredrik

It is to do with multiphase regulation

See here in the manual.

You will probably need to toggle it to individual phase regulation. But read the information first and see what regulations you need to adhere to.
