Sunsynk firmware upgrade

Why did you request the upgrade? Issues with the old software version?

Anyone done a Sunsynk firmware upgrade? I submitted a request yesterday and today my power went out at around 7pm. I was confused... Circuit breakers all still up and Sunsynk was powered... Then 2-5 minutes later it seemed to restart and everything came back online. Was that the upgrade happening?
My current version is COMM: e41b with MCU: 3373

Yes that power out is typically the update happening, as noted above why the upgrade? many people are not touching the new update @AchmatK rolled his back and I am waiting too. My last update was nov 2021

@AchmatK will need to advise, unless this update has fixed the issues

New firmware doesn't like unbalanced strings. It kept limiting my one MPPT to the same current of the other mppt.

I was losing out on generation capacity.

There are some pics in the generator/inverter thread of the issue. I was also not the only person that experienced this issue. I'm not upgrading in the near future.

My biggest problem was that they wouldn't even admit that there was an issue even with me showing them. They kept on insisting that it's working the way it should even after the rollback they still didn't admit that there is an issue with the new firmware.

Even now they would admit that Solarman no longer shows any of temperatures. They just kept on wanting to sell me the new sunsynk logger.

Not exactly.

They just not exactly forthcoming in what issue exactly each firmware upgrade is attempting to fix. There is no information regarding any of the upgrades.

My inverter is running flawlessly for close on two years with the only issue being this one firmware upgrade.
 
I ain't touching a firmware update again. After i get my unit back from repairs it stays on whatever firmware it is.

What broke on yours? Do you recall the versions you upgraded to? How did you perform the update?

Apparently the pc board blew. They replaced the board under warranty. Can't recall the firmware version. You request a firmware update on the sunsynk website.

Hi, just had the same issue. Are you running a single or 3 phase inverter? What was the turnaround time for the repair?

Single phase 8kw Sunsynk
Took about a month since I booked it in till collection.

What problem are you experiencing?

Have a 3ph 12kw, installed it end last year. Was receiving alot of errors which was sorted out with an update. Thought I would get another update this week, can only make things better?! After the update the interface looked like that of a single phase system and inverter stopped working with many incorrect values. Was told the board is damaged, and had to courier inverter to sunsynk (we live in a small town in the Free State). Probably the worst time to be without our inverter.

Lesson I learnt is that if its working don't do any software updates.

A software update resulted in my solar generation being limited and after a few requests I managed to get it rolled back to the previous version.

Unless there are serious issues, do not request a firmware upgrade, ever.
