remote firmware upgrade 6000xp to ccaa-191400 bricked the inverter

Krzysiek_KTA — Sat, 30 May 2026 23:04:37 +0000

I have initiated the remote firmware update to my 6000xp to ccaa-191400 and it went "successful", yet after 30 min or so the inverter stopped working throwing) Internal communication error like the the firmware update failed.

Now I am stuck as I can not re-initiate the firmware update because the system recognizes the latest firmware is loaded.

What a mistake to do it on the Weekend.

Is there any way to re-initiate the firmware update without EG tech support?

new 6000xp came with Firmware version ccaa-00140E

hpeg4 — Fri, 08 May 2026 03:06:39 +0000

new out of the box 6000xp came with:

Firmware version ccaa-00140E

but I can't find that firmware level documented anywhere.

so, I thought I would update the firmware, but when I try to update it via the 'eg4 monitoring web app' by clicking on the '?' I see this:

Suggestion No updates

Has anyone encountered this firmware level and been able to update it?

I opened a problem with eg4 tech support, but am waiting on a response.

firmware update ceaa-1E1414

Looking for information on this update and its stability. I need to update but can't tolerate downtime if things go bad.

does ccaa-1C1212 fix open-loop charging Lithium ?

dtbaker61 — Sun, 08 Feb 2026 21:34:03 +0000

I have a client 6000xp running off-grid and charging LFP with firmware ccaa-191011.... almost correctly, but has a bug which turns off AC-out to loads for 20 seconds or so after hitting vBulk, and sometimes bounces between vFloat and vBulk a couple times before settling to float.

Can anyone verify that ccaa-1c1212 fixes this and does not introduce any other problems ?

secondly.... since this site is off-grid with no AC-in available... the wifi will be powered off if the inverter is in standby mode. Will I be able to do this update for my remote client without going on-site myself to initiate the update and re-start inverter ? I am unclear on how I can do a remote update if their wifi modem is turned off when inverter is in standby and ACout to Loads is turned off.

Does the download of the update occur first, while inverter is running loads ? Does the inverter sequence thru upload and restart without local power for the modem? .... will it work if I do it during the day when PV power is available, or do I need to go out to the site with a dedicated power source for the modem during the update and restart ?

Does the 6000XP support firmware updates on a USB stick?

That's pretty much the whole question, other than what is the update that does a better job of communication to enable EG4 to be selected as the battery type instead of fiddling with lead acid, and how can I download that. I can't find any 6000XP firmware on the EG4 or Signature solar site.

6000xp error 18

Enmanuel_V — Mon, 29 Dec 2025 00:17:49 +0000

Hi community.

Can anybody help me with an issue I am having with my EG4 6000XP? It has been running smoothly since Feb 2015 coupled with a 51.2V 100Ah rack battery V4. Then I bought another battery of the same type. During the day, after the old batt was completely charged, I mounted the new one and started charging it. I didn't turn off the inverter to do that operation as it was the same everything. Then, after sun started going down I started getting inverter shutdowns and after a couple of seconds it starts again. Then I compared two batteries and realized that the can protocol was not the same. I adjusted the new battery and the same happened: checking the inverter log I see the error code is 18(internal communication fault). Then I went back to the old battery and after a while: boom! Again error 18. Can anybody tell what happened and then how to fix it? Thanks in advance.

Update/Downdate 6000XP Firmware at Remote Location

jxnhrpr — Fri, 19 Dec 2025 23:02:02 +0000

I operate one 6000XP inverter and two EG4 280AH Indoor WallMount batteries at a very remote location that has no grid power or cell service available. I don't have satellite internet service (though I probably could). The inverter is running firmware version ccaa-190D0E, and I do not plan to update, because ccaa-190D0E works fine, most of the later updates don't affect my usage, and many 6000XP users have experienced problems with the later versions.

If and when I decide to parallel a second 6000XP with the first, I will either want to update the older inverter's firmware OR 'downdate' the new inverter's firmware to ccaa-190D0E. I have the EG4 mobile app on my smart phone and the 6000XP wi-fi dongle, and I understand the 6000XP firmware can changed with the mobile app and wi-fi dongle.

If I want to update the firmware, is is possible to:
1. download the newest firmware to my phone, when I am home and have a normal internet connection,
2. turn off the phone,
3. travel my remote site, and
4. update the 6000XP using the phone app and the firmware files stored on the phone?

If I want to downdate the firmware on the newer inverter , is it possible to:
1. copy the ccaa-190D0E files (which I have) to an appropriate folder on my phone,
2. turn off the phone,
3. travel my remote site, and
4. update the 6000XP using the phone app and the firmware files stored on the phone?

I am asking on behalf of myself and several members at DIYSolarForum.com. Thanks.

Based on ceaa-191011 or ceaa-1A1111.
1. Add Quick charge function.
2. Add Max AC input setting to reduce the charge power when the AC input over this value.
3. Add time setting for generator charge.
4. Add generator quick start and generator exercise function, remotely start generator for 20 mins.
5. Add generator warm up and cool down logic, waiting for 2 minutes when starting and shutting down the generator.

15. Modify the lower limit of Absorb voltage and Float voltage for lead-acid mode from 50V to 48V

What is latest firmware?

mspohr — Sun, 08 Jun 2025 17:35:56 +0000

I updated my 6000XP which had ccaa-1910 and it said it successfully ended up with CBAA-19xx but when I read the configuration is still says ccaa-191011.

I am confused.

What is the latest version for the 6000XP and do I have it?

It still gives me the option to upgrade again but I don't know if I should.

How do I get my 6000xp to recognize my eco worthy server rack battery

Solarnewbie — Mon, 12 May 2025 14:43:43 +0000

Is there some code I need to do? Other than setting it up as a led acid battery
