Hi all. We have a 3kW Kodak Inverter that we would like to sell (we recently upgraded to a 5kW). The inverter is in perfect working order and is about 18 months old. It comes with the wi-fi dongle as well as the original packaging and manual. I do not know what a reasonable price would be, so I would welcome any suggestions in that regard. Many thanks.

Thanks Tim, I also did that a few days ago and it did the trick.

Yes, that certainly makes sense. I have changed the minimum SOC to 25% and had no problems this morning. I'll keep an eye on it for a week or so to make sure the problem has gone away.

@Tinbum below is a screenshot of the SOC today...

I am pretty tech savvy, but I would be a bit worried to attempt the firmware upgrade myself... these batteries are pretty expensive toys to break if something goes wrong! I will ask my installer about it and see what experience he has had with upgrading firmware on older batteries. In the meantime, I have set my minimum SOC to 25% and will monitor and see how things go.

I have no idea, but if all three batteries are now behaving as one I would think the placement/order of the batteries would make little difference. This is how our installer set it up when we recently upgraded from one battery to three. Are there any experts out there who can comment on this?

Yes, one of the batteries is about 4 years old, the other two were purchased within the last month. What you are saying certainly makes sense, I am sure the older battery is draining faster than the new ones. I have made the setting changes suggested by @Scorp007, so hopefully that will help as I am concerned that this issue might be damaging the batteries. I will search for batteryview software and see if that gives me a bit of insight. Thanks to you and @Scorp007 for all the assistance, much appreciated.

Thanks Scorp007, I will change those settings and monitor for a few days to see if it resolves this problem.

No, the inverter did not shut down, it was still running. Only the battey was showing 0% charged. There were no error / alarm lights on the batteries - below is a photo I took of the physical batteries...

Hi everyone. I had the same issue again this morning... batteries were at 22% at 05:30 then at 0% by 05:35 (see attached screenshot). I checked the physical batteries (as suggested by Nexuss) but they were completely dead. They stayed on 0% until 07:30 at which time they started charging (I assume this is when there was enough PV). What I find odd is that it is happening randomly (every 2 - 4 days) and always between 5am and 7am. The rest of the time everything works perfectly. Has anyone else experienced this issue? Is it possibly something to do with my battery settings? (I have attached my settings below for you to view). Any suggestions / recommendations would be welcome.

Thanks for the advice, Zsde. I have unticked the "time syncs" option which seems to have helped. I will keep an eye on it for a few days and make sure it has resolved the issue. Regards. Grant.

Hi all. I noticed something strange for the first time today on my 5kW Deye inverter... the time was 1 hour ahead of the actual time. I went onto "basic settings" and changed it, but a few minutes later it went back to the wrong time again. Has anyone seen this issue before? Has it perhaps got something to do with the "time syncs" option being enabled? Thanks. Grant.

Thanks for the advice, Nexuss. I will keep an eye on it and compare the SOC lights on the batteries themselves if it happens again.

Hi all. I have a 5kW Deye Inverter with three Pylontech US3000C batteries. On a few occasions over the past two weeks the battery SOC has dropped from around 20 or 30% to zero in a matter of seconds (see attached screenshots). Can anyone advise on what could be causing this? Is there possibly a setting that is not set correctly?
