So I currently have (3) EG4 LL V1 batteries "with updated Schneider firmware" in closed loop with the XW Pro 6848 system via the Insight Home. I think it has all 3 batteries reporting, as the max discharge current in the BMS Monitor shows 300 amps. The Insight Home and XW PRO 6848 was updated to the LATEST firmware. (Insight V1.17 Build 79 and XW Pro 6848: V2.04 Build 29). I think this update might be important, as it adds some SOC functionality.
It was a process and any one thing not right and NOTHING works.. I'll put the steps I followed below:
1. Get the "special" cable from Signature Solar. They sent me a USB adapter and custom cat 5 cable. "the one the shipped with batteries would not work"
2. Updated all the firmware on all the batteries.
a. Shut all the batteries off "breaker and on/off switch"
b. Set dip switches to ALL down
c. Turn the battery on "leave breaker off"
d. Plug the signature solar update cable into the RS485 port of battery you want to update.
e. Using their firmware update program, load the shnieder hex that came with the updater then choose the com port your cable is assigned, click open, then start. Wait for it to finish successfully. Battery will reboot when done.
3. Hook a cat 5 cable to the Insight Home to your main batteries RS485 port. On a standard cat 5 cable you will hook Orange/White to upper right most connection "when looking pin outs on Insight Home. Then Orange to the connection left of that. Sorry no pic, but SS has a video showing it pretty good.
4. Set the main battery hooked to the Insight Home to ID 1. "Right dip switch up, all others down"
5. Set all the other batteries to something other than 1 or all down. They need to all be on a unique ID. Daisy chain batteries together on battery com ports with cat 5 cables.
6. Power cycle each battery after dip switch setting have been changed via the on/off switch
7. Log into the Insight Home GUI. Go to Setup -> Detect Devices. Type in 1 to 10 and click detect. It should find your battery.
8. Click on Devices and you should now see the Schneider BMS Monitor show up. It might take a min or two. I didn't think it worked at first, as it didn't immediately show up. It was several mins for mine and then there it was after a refresh. Click on it and verify all batteries are accounted for, by looking at your Max Discharge Amps. 100amps X the number of batteries you have is what should be showing. I have 3 batteries so 300amps.
9. Here's a missing step in all the videos I've watched. You have to Associate the NEW BMS Monitor to a battery. Click on the BMS Monitor in Devices, then click on Configuration. Choose House Battery bank 1 for Device Association, unless you are using a different one than default. You can also Name the BMS in Device Name.
10. You should be ready to switch the XW to closed loop now. Inside the Schneider web GUI, go to Configuration -> Battery Setting. Set Battery Type to Li-Ion, Set Charge Cycle to External BMS and enable SOC control. There is a chance the XW will go into standby mode shutting power off to it's output during this. Be aware of that.
11. Finally you can adjust the BMS communication parameters to what signature solar suggests or your liking. Go to XW Pro -> Battery Management System Setting. Click on advanced button to see all options. Here is what I currently have:
12. You should also go configure the SOC setting in all the other settings to suit your liking. like Grid Support, Battery settings and Charging settings.
Hope this helps someone. I wish I had a more complete guide than what has been provided by Signature Solar in their videos. In fact they don't even say the EG4 LL V1 will work with the XW Pro 6848 in closed loop so I never even tried until
@JFKS mentioned he got it working. I then was on a mission to get mine going.
