I sent them an email and had to call when they did not reply. The card is easy to remove, but took me about 30min as I was very careful not to cause damage when I removed the white glue/silicone on the card.

Hi @GreenFields,

Many thanks for taking the time to respond in such detail - it really helped to clarify my understanding.

I have a few more comments and queries in response to your post (and all these questions pertain to scenarios while grid is not present) :
For clarity, is this "solar power" setting a minimum solar generation value? So in my case would the MPPTs need to be harvesting a minimum of 4000W before it considers switching power to the AUX port?  I always thought this was a maximum value, and hence my confusion.
So if the battery SOC is at 100% AND there is more than 3000W of PV generation, I would assume that the AUX port would be active.  Then, let's assume there was some temporary shading from a cloud.  Would you expect the AUX port to switch off during the shading?
I also found the attached document which was very helpful.

Best regards,
Ryan

Hi Neil if you didn't get somebody to sort you out i build standby units in 480w, 640w, 800w and 1200w ups units with 2 x 12v 1280wh lifep04 drop in batteries in parallel for the 480w and 640w units and ESENER 2.56kWh 24V LIFePO4 Battery Module for the 800w and 1200w units. I have installed 103 units already. Remember not wired into db board needs 1x15A socket outlet that is on the main earth leakage. You can pm me if you are interested.
