AC Firmware problem

Christina

Hello.

I updated several other firmwares from the app with no problem. The AC Firmware updated once without an issue, but the app then said there was another Firmware update. As I was updating the second time it got stuck at 90%. I seem to have an error code that changes between 015 and 016.

Can you help?

Thanks.

My SBV4600 is doing the same thing, but I have not seen any error codes, and the AC firmware version shows "V0".

Zendure support, could you please respond to this issue? Thanks.

This is the wrong version of the BMS, please don’t worry, keep the device online, then contact us by email, and then update the BMS firmware, and it can be used normally. support@zendure.com

Yesterday turn on and AC firmware miraculously reads 2.1.10 and unit acts normal all day. Turn on today AC firmware reads VO and it wants to upgrade to AC firmware 2.1.9. AGAIN. These are obviously not ready for prime time, and I would like to ta refund as I don't have time y waste on this daily. Zendure how do I get my money back?

So I did the firmware upgrade AGAIN 2 days ago which then listed version 2.1.9 as the current version (2.1.10 disappeared). SBV worked fine for 2 days. BUT when I turned it on today AC firmware listed AGAIN as "V0", requiring is

My SBV is obviously broken requiring constant surveillance and repair to the AC firmware. SUPPORT whatis the process for returning my broken unit for a new one, or for a refund? Thanks.

AC V.2.1.11 firmware solved the problem for me.
