Is the AC-out switching? if not then I'd look into the PV inverter first to see what is happening and why.

Hoi, no.. no ac out switching... load stays on, only the inverter goes down, but its something to do with ( i think) ... battery full ( absorption / float) and more pv power than battery loading + ac out load + feed in (19A) = pv goes out...

Yes, I agree.

The regularity of the shutdowns are also a clue if the load is steady.

If 19A is the max allowed to export back into the grid setting, it may be that this setting is too low.

Is this setting self-imposed?
