shovelhead Posted April 29, 2023 Share Posted April 29, 2023 I haven't changed my Sunsynk time recently (not in months that I can remember) and noticed that it appears to have gained an hour - I set it back an hour, and a few minutes later it advances another hour. I noticed that it is set to "sync" so going to try and untick it now, but wondering why this has changed all of a sudden. Has anyone else experienced this ?

mzezman Posted April 29, 2023 Share Posted April 29, 2023 Could be syncing with a time server that's moved an hour ahead? Try untick sync and see if it keeps the time over the next 24hrs zsde 1 Quote Link to comment Share on other sites More sharing options...
zsde Posted April 29, 2023 Share Posted April 29, 2023 It does sound like a daylight savings provisioning at their sync server level. SA does not have daylight savings which begs the question whether the inverters are registered by country and serial number and that it may somehow linked to a country that does have daylight saving. Or the sync server may have SA in error as a daylight saving region? Scorp007 and mzezman 2 Quote Link to comment Share on other sites More sharing options...

mzezman Posted April 29, 2023 Share Posted April 29, 2023 They should give the option to specify a time server in the apps zsde 1 Quote Link to comment Share on other sites More sharing options...
sgs Posted April 29, 2023 Share Posted April 29, 2023 My Deye has done the same. Drove me nuts before I figured out what was happening. I suspect it is related to the timezone setting in Solarman. Mine is set to GMT+2 Cairo, and Cairo does have DST, which kicked in last Friday. There is no way to change this though as my installer controls the plant in Solarman. Does anyone know if Solarman has a timezone for South Africa, though? If so I need to shout at my installer to fix it or to give me control over the plant in Solarman so that I can manage it myself.

mzezman Posted April 29, 2023 Share Posted April 29, 2023 Solarman does indeed have a Harare/Pretoria timezone Quote Link to comment Share on other sites More sharing options...

I thought this would be the solution, and changed mine from Cairo to Harare, Pretoria. Unfortunately it still adds an hour within a few minutes.

Unfortunately it still adds an hour within a few minutes. The time server that it syncs with belongs to Sunsynk, not Solarman. I had a similar issue where it placed mine in a GMT timezone, so I asked support to intervene on the Segen Sunsynk group. They never gave me any feedback (seldom do), but at least it was fixed. There is a lot of value in having a time sync, just a PITA when it goes wrong. It would be nice to be able to select timezones on the Sunsynk inverter, as well as a user-defined local one, or a proper stratum-2 time server from http://www.time.org.za/ Quote Link to comment Share on other sites More sharing options...
gthorn Posted May 9, 2023 Share Posted May 9, 2023 I'm having the same problem. I noticed it yesterday for the first time. I fixed the time but I just noticed that it jumped an hour ahead again. I have now turned off "Time Syncs" to see what happens. I have a Deye 8kw inverter and it was connected to SolarMan when installed last October. I have a friend who installed the same setup a week ago and he does not have the problem (so far). His inverter is not connected to Solarman, so my guess is that Solarman has something to do with it.
