It is on the master inverter yes, settings have carried across to the other two inverters. 

I did speak to the installer and he got Deye to run through a firmware update process  again.
 
The master inverter now has the following versions:
HMI Version: 0000-C36F
MAIN Version: 0-6027-1724
Both Slaves have the following versions:
HMI Version: 0000-C36F
MAIN Version: 0-6027-1724
Looking at Solar Assistant now after the firmware update batteries are reporting as 99% and the solar is enough to run the house load.
Grid power is between 76w and 120w which I would expect as the Grid Trickle Feed.  
 
So I am wondering if there was not an issue on the previous firmware on the master inverter.
Will see what happens if the batteries report as 100%. CAN cable is plugged into the master inverter.
 

That’s my thoughts. Run the coldest geyser earlier and the hottest later. That I think would also increase efficiency. 
 
Will look into this avenue. I’ve gone through your post on my broadband and it looks very comprehensive. 

Hi guys, sorry for the delay in the responses. Things have been a bit crazy. 
 
Thank you all for the valuable input. @Sc00bs thanks for the video, very informative. 
 
i am currently not at home but will definitely look at these suggestions next week and will revert back. 
 
Have a great Easter guys for those that celebrate, but most important have a safe one and enjoy the time with loved ones. 

What other impact will max discharge have if it’s set to 200A? We are looking at getting another battery, as I do feel that we should have 3 minimum.
