Power loss/interrupt when switching from grid back to battery

The power generator is started with an automation in case the battery volts fall down a limit. At the moment battery volts reach a certain value the generator is stopped, also by an automation. At that moment a very short interrupt, power loss, happens.
This leads to that my new Bosch baking oven fails: Stops working.

I searched the Axpert 4K documentation for a parameter that could prevent that, without success.
I hoped of a possibility to charge the batteries without power the equipment at the same time. This way there would not be the need to switch the power source from battery to grid and back again.

I have two Axpert 4K in parallel running.

I’m thankful to any idea o recommendation i could try out.

If there is no soft solution i probably install a small UPS to bridge the gap!:frowning::sweat_smile:

It’s not going to be a “small UPS” if it needs to be able to supply enough power for an oven - even when not on battery power. The power rating is the same for both grid and battery backup.

This seems like an issue with your inverter, not HA. Have you tried asking their technical support?

Hi Tom,
thats correct. I’m not expecting a solution from HA. I’m thinking that there might be a user who can give me some advise.
And yes, the technical support is advised. My experience is that they refuse to even analyse the problem if they hear that a photo voltaic system is involved.
The oven should have a small battery installed that bridges small interrupts - for the electronic part only!
