Recovering bricked / bootloader schneider context XW inverter with InsightHome

@hwy17 Out of curiosity, with v1.17, do you see BMS settings when you go in Devices, under "Other Devices"? I see nothing on my end with v1.16.
 
I guess it's because your battery type in your XW+ settings is Li-Ion? Mine is still set to "custom" (I am still using my FLA batteries, soon to be replaced with customer LiFePO4 build).

Have you tried 1.17? I thought mine were set to custom as well. But my system is off right now and I'm not gonna mess with it now until it goes live again later this week. I can get screenshots then. I thought it always appeared when on 1.17.
 
No I haven't tried v1.17 - I'm curious if that setting appeared in v1.17 or if it appears when you select the Li-Ion battery type from the XW+ settings. I guess I'll know more when I start messing around things when I build the new battery - but it'll only be in a few weeks from now.

Actually I did not see this setting today. But my xanbus is acting up, so everything's out the window again. I'm gonna try 1.16 now.
 
@hwy17 LMK if it's better with v1.16 and LMK what's your configured battery for your XW+. Thanks!
This appeared for me today while on 1.17 with only the MPPT 100 600 connected by xanbus, and the 100 600 had Custom in it's battery settings.
1.16 didn't really do any better for me now, I'm on 1.17 again. But my xanbus is all messed up, no devices are appearing now.

I might just leave it broken. The charger and inverter are doing their job, and I won't be using BMS comms my DIY BMS is what calls for the grid charger in my system anyway.

@hwy17 So you haven't had the chance to verify if it was shown using v1.16?

I might not care at all about that setting anyway. I read that closed-loop communications is only possible using an XW Pro. I'll likely use my Raspberry PI to read settings from the JK BMS and perform some actions on my InsightHome over modbus TCP (like starting the generator when the SOC is low). I already have a Conext BattMon which I think should be good enough to act on voltage readings alone, and I could try to automate ops based on SOC settings on top of it.
 
I’m in bind here . I have acquired new in a box sw4048 from Facebook marketplace. This thing was not used at all.

I brought it home and wanted to see if it works . Connected it to the combox I have with my existing system which also uses the same inverter.

I could never see it in on the web interface of the combox. I can see it under the upload menu in boot loader mode . When I upload firmware it seems to complete the upload . Here is where things fall apart . I should be able to see the firmware under the inverter in the bootloader mode. The drop down is empty. When I switch over to my existing system (require the cam is and disconnect the new inverter) I can obviously see the devices along with multiple firmware’s I uploaded over the years I owned the system.

Why cant I see any of firmware I uploaded to the combox? It is there but will not show up once the new inverter is connected to the combox.

In this video it shows the inverter in boot loader mode and once selected the pull down menu has the list of all firmware ( minute mark 15:50 ) . Again in my case this pull down does not show anything.

Are they both model 865-4048?

Combox looks at the model number in the firmware file and matches it to the model number of the xanbus device.

If it's not showing in the dropdown then either the model name is different, or it's not successfully reporting it's model name when it's discovered in bootloader mode.

Try leaving the combos online and powered while restarting the inverter, or the opposite, restart the combox.

Sometimes, disconnecting the inverter from the battery and waiting a couple hours for the caps to fully drain all power out of the inverter before trying again seems like it helps.

Let me also just say I have put both my devices into bootloader many times and several times felt like I broke their xanbus even worse than I ever had before, and they've always made it out ok. The bootloader mode is very resilient, even if the recovery process is not reliable.

Yes they are. According to what I have seen online the inverter (or any device in boot loader mode) will list any firmware from the uploaded ones for me to select from as it does not know much about the device in that status. This is not the case in my case . The drop down is empty so I have zero chance to even attempt to load the firmware. I need to get passed that step to proceed to recover the inverter .

This is reassuring to hear. It seems I just need to get passed that step. I think resetting the combox would be the next step but
a) I don't want to loose all the logs data on it ( it did make a back up )
b) I don't want to loose the settings ( I know there is a way to back up the setting and restore but I have not come accross the actual software to download )

That is not my experience as I recall it. I thought the bootloader mode was still selective about the firmware, and if it's failing to offer any I think the bootloader recognition process needs to be reattemped.

Do you have a 12v barrel power supply for the combox? I would try a drain of the inverter caps and then a fresh start of the inverter, while the combox is already powered, on a standalone xanbus with a terminator in the combox and the inverter so it's just the two devices.

I have tried that but never had a combox reset be the solution to the problem so I don't bother trying that myself anymore.

I have 12v barrel power applied. Had the inverter disconnected for 12 plus hours. Have the COMBOX and SW connected to xanbus only with terminator at each device. Below are screen shots for both setups ( same combox ) working with my system and then switched over to the new SW only.

upload as it should be working
COMBOX - OK.jpg

this is what the problem is.SW is showing it boot loader mode. Yet I can see the firmware I just uploaded.

COMBOX - NO GOOD.jpg
