Thank you @GreenFields for this. I think this will give me more to think about and answered some questions about settings.
 
To clarify, I intend to put the entire house on backup load and keep the distillery as non-essential/house load. If there is a power outage, I am not worried about the distillery. We have fairly stable power in Slovakia and when the power does go out, it is usually only for a few hours. Nothing in the Distillery will be affected. 

I have started to look into the Time of Use settings. My goal is to never use grid power in my house. I have several friends in my local area that have much smaller systems then I have, and have been able to get about 90% of their power from Solar and Battery throughout the year. We over-sized our system significantly to account for the distillery loads when cooking, and will likely need to pull from the grid on brew days only. At least that is our intention.

Thank you again. Your explanations make sense and I feel a bit more confident we will get to where we want. I hope to get everything install next month. I will be traveling for the next few weeks, but plan to start immediately when I get back. I am sure I will have more questions along the way. 

Below is the basic setup I was sent from the factory for reference. I built a dedicated room in our space for the equipment with ventilation. I am excited to get started.

Hello,
I ordered and just received a complete solar system from SunArk for my house/distillery in Slovakia. 30kw capacity of panels, and 6 200Ah batteries. I did a bit of research before purchasing and thought I had everything thought through but now I am not sure. Slovakia has pretty strict rules on grid connections and I do not plan to be officially connected to the grid to sell power back to the grid. My plan was to only use grid power to supplement the distillery and charge the batteries if needed. 

My inverter setup is 3 DEYE SUN-12k-SG04LP3-EU units. I wrongly assumed I could setup the system in a SBU mode and now I am not sure how I should manage the loads. I want to reduce the risk of even sending back a small amount of power to the grid.

My thought now is that I should run the whole house on the Backup Load output and only run the Distillery on the GRID/House Load output. My reasoning is that I believe the system size is more then large enough for running my house and should not need supplemental power from the grid.
The distillery is a small commercial distillery but more on the scale of large hobby. The auxiliary power needed for the  distillery is minimal, however the Still itself has 3 7kw electric elements, but will not be at 100% for more then an hour or so each time it is used. When the system is up to temp the power will be reduced to 1-2 elements. Another note about the operation is that we will only run the still 1-2 days per week in the fall and possibly less during the rest of the year.

I am not sure which Zero Export setting would be best to use or if my thinking on which load outputs to use is right. I orginally thought I would have all outputs on house load, but I would like to keep the whole house operational even if there is a grid power outage. I was hoping I could run it in "island" mode and use a mechanical switch to gain power from the grid to supplement, but I know realize this system is not really designed for that. 

I would appreciate any advice you may have about this.
