Solaredge inverter start up voltage?

I was wondering if anyone has had success in lowering the start up threshold on their solaredge inverter?

We seem to have about 20 minutes discrepancy between the Victron unit firing up, then Solaredge kicks in later.

Watched it remotely today and it kicked in at 385Vdc and started producing 110W This isn't a big deal but as I'm replacing the Victron solar controller I thought I'd do what I can to squeeze all available power from the solaredge too. I'd rather it kicked in earlier? Any experience on this?

Prefer a startup.of 360vdc and a handful of Watts being produced? It can do it as seen in the photo but only once up and running.

Most SolarEdge inverters are designed to operate with a fixed DC input voltage to ensure DC to AC conversion efficiency.

Cant you change your array to meet it earlier in the day?

Sadly no, although some felling may take place.

Is it all one string?

Yes, looks like the start up.voltage for the inverter is 350vdc. This is according to online docs. I am distant from the equipment and manual at the moment so can't play about with settings which tbh is a good thing!
