Hi Bluetti_CARE,
I have an EP760 that is grid connected and also AC coupled to my existing Solaredge 6.6kW solar system.
Currently, I charge the EP760 exclusively from solar production. I never charge the EP760 from the grid.
As it is winter in Australia, my daily solar production has dropped and I want to find a way to increase it.
I am considering adding some PV panels directly connected to the currently un-used PV inputs on the EP760.
Are you able to advise whether the EP760 logic will allow the battery to charge from these new direct connected PV panels as well as the existing AC coupled solar system in parallel? Or does some other logic apply?
Thanks for any advice you can provide…

I thought that it would be good to provide my own answer to this question in case anyone else is interested.
After adding some additional solar panels directly to the PV3 connection on the EP760, I found that the additional power generated is simply added to the power from my AC coupled solar system in the main view of the Bluetti app.
If I tap on the “PV” icon, I can then see an individual breakdown of the power from PV3 solar panels separately to the power generated by my existing AC coupled solar system (PV4 - AC PV).
See screenshot below.
The power generated by PV3 and PV4 are simply added together to either charge my B500 batteries, or run my local loads, or to send to the grid.
I am happy with the way this works.
One thing I am yet to determine is whether this setup change will exceed the 5kW limit that currently applies for grid feed in.

Answering my own question again, the 5kW grid feed in limit is set in my existing Solaredge inverter, so in theory, there is a potential for the grid feed in power to exceed 5kW when there are no loads being supplied and the EP760 batteries are not 100% charged.
Note that once the EP760 batteries reach 100% charge, the EP760’s internal solar controllers will switch off and stop feeding to the grid. At that point the 5kW feed in limit cannot be exceeded.
