Reset to factory settings?

Ingo.falkenbach@googlemail.com

Hi everyone. Is there a way to manually reset the SBV to factory settings? After the last AC firmware update, the AC controller is not working anymore. Error code 003. I'd like to undo the update but how? Zendure support is not responding and there is no firmware file for download on there website.

While it's theoretically possible to downgrade firmware using a USB drive, you'd need the files from Zendure to do that. However the 003 error code indicates a loss of communication with the AC controller. I doubt that it will be able to update or downgrade firmware in that state. This device will most likely need to be replaced.

Well, thx for the encouragement ;-). My hope is that zendure support will reply soon to deal with it, one way or another...

Unfortunately I have the same problem. I wrote back and forth with the support after DC update. Unfortunately also without result. I was just waiting for the next update. Now DC worked.. but not AC neither charging nor discharging. reset 3 seconds AC and LeD switch. I'm not responding. Support is absolutely incompetent and do not believe and understand the problem. I hope for the next update. I hope that it will come soon. Otherwise everything will be useless

I too has the 003 AND the 217 errors and support sent a truck to pick up my unit. Hopefully I’ll get one back. At least you still own one even if it’s broken.

Update: after 4 weeks chatting with support and trying several things, my device was replaced. I have to admit, that, at the moment when replacement was agreed on, the whole process went very fast. Zendure delivered replacement within a few days and fetched the old one. (From most companies you're asked to send your defective item in and wait for the replacement). So, good job at that, Zendure. Hope that the issue with the AC controller will not happen again. Firmware is now up to date....
