Could you please post the complete system setup.
Did you install the PV Inverter support?
I used the VS, and then the AC-ignore option, so no assistants, this works great:
I will try the PV inverter assistant.
My question is: can/does this assistant charge the battery when AC-in is connected (instead of dumping on the grid)?
and does ignore AC-IN (or similar function) still work somehowā¦
If your PV power is higher as the power who the MP can taken in ( nearly full batteries) the PV power has to go somewhere. Since there are no consumers, it goes into the grid.
The AC assist raises the frequency and thus trips the AC solar inverter. However, this only works in island mode. For Grid mode you need a steerable AC Pv Inverter like Fornius.
Other solution would be to switch to DC Mppt or a seperate AC/DC charger who will controlled by the generator relay
What is a high flux proton deceleration generator?
Either assistants or VS.
But you can probably put something together with the General Flag assistants.
To be honest, I donāt have any experience with that either.
So the ac solar inverter is steerable, so no probems there.
The situation iām considering is when the battery is almost empty, so solar always has to go into the battery (not to the āgridā, that would be a waste of energy).
So i will try the PV assistant, maybe it will not send power to the gridā¦ I tried the general flag assistant before, did not have much luck with that, but will try again.
Itās a high school science project 
I played a little around for you, Worksā¦
You must limit the AC solar inverterā¦this is not a Victron problem, it is a AC PV problem
I canāt imagine that the MP canāt process the AC solar power. Did you det DC Charger to maximum?
Otherwise, try again with the solar/wind prioritization.
I googled for high flux proton deceleration generator
But didnĀ“t understand the backround.
