In that case, I can't think of any reason to buy a hub.

Thanks so much for posting the YouTube link. I've got the hub, EG4 6000ex and EG4 LifePower4 batteries with Solar Assistant. I never tried connecting my Pi to the batteries with the USB cable while they were connected to the hub, but I did today and finally have all the battery data in SA. I'm pretty sure others suggested this worked with other inverters but I guess I'm a little slow.
Thank you! Appreciate the video. Coincidentally, I had ordered a Hub earlier this week... hadn't arrived yet. I'm currently running 6 Lifepower4's & 1 6500EX & 5.6kW bifacials. I have a 18kPV & 1 PowerPro sitting in the box for the house we are building. The plan is to add a 6000XP & 2 more PowerPro's along with my Lifepower4's. (I will be selling my 6500EX. ) OK that's the background.
So I noticed that you have an 18kPV AND a 6000XP working together & this Hub seems to be very helpful. Do you also have any PowerPro's in your system? They have been saying you can't use these both together with Lifepower4's AND the PowerPro's...yet. Love to have any input you can offer. Thx

Personally, I would be fine using both battery brands/designs in a shared battery setup.
Thank you, that is the plan.
I'm thinking the Hub will be useful going forward.

The HUB isn't compatible with the PowerPro batteries.Thank you, that is the plan.

Well it doesn't communicate. (Maybe in the future.)Dang. I wonder why?

I purchased the hub and then saw on SS that it would not work with Growatt. When I called SS they informed me it would not hurt anything, but it would not do anything either. So I returned it.

Yeah, I know and when I called they admitted that it would do nothing for the growatt, I had three of them before they all failed. Now I have paperweights

Whereas the Communication Hub is not necessary with the Growatt inverter to communicate. It can be used in conjunction with the Growatt to show more detailed information about the LIfePower4 batteries.

But that is not what SS told me, I was told it would do nothing with the growatts
Which is really the same case with things like the 6500EX's & LifePower4's. Correct?

That would be correct. The main use case for the communication hub is for inverters that require a different communication protocol or CAN communication.
What voltages would I want to put if I were setting it to open loop?

CHARGING VOLTAGE (BULK/ABSORB) 56.2V (+/- 0.2V)
FLOAT 54V (+/- 0.2V)
LOW DC CUTOFF 47-44V (Depending on load)
