Multiplus 12/3000/120 ac-2

What is the problem?

Before the ac2 230 power only went on as I plugg in shore power.

Now it’s on as soon as I turn on the Multiplus…

I haven’t changed anything…?

Ac out 2 relay is faulty and permanently closed or an assistant has been installed.

Ok!

No assistant installed.

How open ac2 relay or check if it faulty?

@Dailycamper the AC out 2 relay is programmed in software to close after mains power has been applied for about 2 minutes. It opens if the multiplus switches to inverter mode.
It can be overridden by software called an assistant.

If you have voltage on AC out 2 when the multiplus is inverting it sounds like the AC out 2 relay is faulty or the software driving it is faulty.

You could check its operation if you have the technical skill to do so.

@Dailycamper may I ask what firmeware revision the Multiplus is? Also do you have a CergocGX in your system? I have seen the same issue today on a Quattro with Cerbogx. Cerbogx version 3.51. The issue I am seeing is slightly different. Mains is applied, the cerboGX cannot see any mains on input of Quattro. The Quattro is in inverter mode and AC Output 2 is active apparently using inverter power…

I have firmware 552 on the Multiplus and yes I have a cerbogx with os v3.52 on it…

Maybe that why ac2 just disappeared…?

Is that something that you can check @dfaber ?
