Hi Barfo,
I sincerely apologize for the inconvenience. I’ll send you a troubleshooting document via PM first—please check if it includes a solution for your issue.
Once the technical team returns on Monday, we’ll provide you with a detailed resolution.
@Barf
Please check Point 2 in the file:
Additionally, could you share the serial number with us? Our engineer can then remotely diagnose the cause of the output interruption.
Hi
it’s EBOX2422000122596 for the EMS-Controller and EP20002445000300374 for the EP2000 itself.
but it’s not connected to the cloud.
for the mean time, is it possible to revert the firmware to the older revision? I had about 10 power losses over the weekend.
Without an internet connection, the tech team can’t check the cause remotely. It’s best to check with us via cloud connection.
See if the firmware upgrade has turned on the parallel function?
Also, do you know which firmware was upgraded to cause the problem?
Hi,
I’m not at home but I’m pretty sure that off-grid parallel is off (I checked all options). Maybe I can enable and disable it again when I’m home.
for the firmwares, see my first post.
Software Revisions:
IOT v9052.16 (was updated)
HMI1 v6062.19
HMI2 v6063.05
ARM v5032.11 (was updated)
DSP v5030.11 (was updated)
Safety module v1076.04
BMU v1075.04
BCU v1074.04
I’ll try to connect the system to the cloud when I’m home.
Hi Bluetti team
the device is hooked up to the cloud. As you won’t have access during a power loss I have to set the transfer switch to Grid and connected my Climate Unit and a light bulb to the backup power.
I also did a reset in Pro Mode and in the advanced settings. lets see…
I still wonder why I cannot setup the custom working mode. Is this going to be removed?
@Barf Hi Barfo,
The engineer has adjusted the parameters in the backend—your system should now work normally.
The custom mode is in Advanced Settings
Hi Bluetti Team
the system ran during the night without problems (it’s 6.20am here right now).
I can see the custom mode in the app but not on the EMS-Controller. Will this be fixed?
I’ll test the behavior in the evening (it was running like Backup mode even when set to self consumption)
thank you for your support.
Engineer’s response: Sorry, this is not visible on the EMS controller.
Dear Team
I had a power loss again. And it seems to be impossible to deactivate WLAN. Or it gets turned on after a restart of the EMS Controller or something.
Please, could you revert the last update?
And once again around 6:35 am Germany Time
Hi Barfo,
Engineer Mike checked the backend for you:
Historical log entry at 6:35 shows no backup power interruption occurred. Currently, parameters and status appear normal. Please provide details of the operations performed during the power outage, error codes, and other relevant information.
I’ll share Mike’s WhatsApp with you via PM—could you add him to provide more detailed information? This way, he can offer faster support in the future as well.
Hi
Yesterday around 17:30 I restarted the hole system because I had to check something. Power Loss was around 3:30am in the night. I found out because the radio where i was sleeping was off. so I turned the System Switch on again on the EMS-Controller.
Same for the 6:35am incident. Nothing was done at the system at this time, it just turned off the AC Output. When looking at the EMS Controller you can see the System Switch being turned off. To get power back I simply turn it On again.
Whenever this happens, the system switch on the EMS Controller is off and there are no entries in the logbook. “System Switch Recovery” is on. I don’t know why, but the system switch seems to be getting turned off.
The entries you showing is the video are the ones for the missing grid power. That is all correct, the grid is disconnected. Mostly because of the problem in my other post from EP2000 constant Grid Consumption - #3 by Barf
But I did not have time to look into this by now, first the power loss has to be fixed somehow.
I mentioned before in this thread that before I made the update of the system I sometimes saw that the EMS-Controller showed the home button being red, when coming near the EMS-Controller all shown values where “0” even the battery %. After one or two second all values were present again and the home button went green/yellow again. No entries in the logbook regarding this. Maybe this helps.
Sorry, I don’t use whatsapp. Is it possible to use email instead?
Please tighten the EMS communication cable according to the video guide.
Yes you can contact Mike via email.
Hi
it’s tightened, I’ll try loosen it and wiggle it around to see if it haves any effects. But I’m not home right now.
When the power losses appeared now one was near the Controller, especially at night ;-)
There are no Vibrations near the Controller.
The problem with the power loss was solved with an Update.
Thanks for the help. Great Service!
Hello … would you please be so kind and send me the troubleshooting document to … I have two ep2000 devices that have an B149 Grid Problem … Thx
Ok，I have send it to you
