William, Mac and Wrenches,
Though it’s not the specific model William seeks I’ve generally had good luck
with closed loop comms paired with the Fortress Eflex. I did have initial
setbacks with earlier firmware since the particular setup still had a negative
to ground bond but after their

In my comversations with SMA, they made it clear they do not support closed
loop comms with anyone

That's actually incorrect, Fortress totally does support closed-loop with the
SMA Sunny Island inverters. Here is their integration guide. This has all of
the instructions and coms wiring, etc. -

Kieran:
I have read the documentation. Fortress tech support said there have been
problems and recommended open loop.
Do you know what parameters are passed with closed loop?

Jerry,
Who is the maker of the Blue Planet/Outback SOC box interface you mention?

SMA and fortress can only open loop and with a fixed temp sender its fine.
Now on the blue planet and open loop with outback, you need a SOC box that
they can make for you, it will interface with the blue planet and command
the genny.

Hi William,
Are you doing open loop or closed loop communication? I'm not sure if
Fortress can do a closed loop with SMA or not.
We struggled to get the open loop to work well with some Blue Ion
batteries, not from a charging sense but from a sense of getting the auto
gen start to trigger
William, Wrenches
Yes I do and it does require some basic electronics to make it work
correctly, you will need to remove the ttemp sender and make a
resistor pack to simulate the 77 degree reading otherwise it will not
charge properly, for the first one I used a breadboard to set the temp for
what
Friends:
I am commissioning an E-vault battery array to an existing SMA Sunny Island
System. Does anyone have any experience with this they could share?
Thanks.
