12/800 in Eco mode gives High AC-Out voltage alarm then switch's off

Dear all
Just bought a brand new Phoenix inverter 12/800 230V pin121801200 after connecting it to my Pi (connect to vrm) I received

Inverter - Phoenix inverter 800 [291] Automatic monitoring High AC-Out voltage alarm: Alarm

the Inverter is in Eco mode wake-up 15Watt search 3Sec for 0.16S

when I attached my Fluke 87v Min Max I get a max of 246V although it is set at 230(fluke reads 228v)

and then it will switch off restarting after a minute or so it starts again
is my Inverter broken?, do I have to have it replace?
or is there something I can do

Ps.the load on the inverter is a frige AEG RTS9143XAW only 80Watt

Theoretically switching off the power to a inductive load causes a high "kick back" voltage (not sure if this is the correct term in English).

(This is used to create the spark at the spark plugs in an engine)

But I'm not sure if this could be the case with your fridge.

Can you test it without the fridge or with other loads.

Moin Matthias,

I find it strange as with my other smart 12/2000 Phoenix inverter which had this fridge on it, I never had this issue before

But

I will try that with some old fashion lamp over the weekend.

thanks for sharing your thoughts .

Ray
