Just checked my 12kW: SW Ver.：M 2005-1172 / S 18-07 / C 1001-E04F How does this correlate with the version scheme in your table?

Brilliant! How on earth did you find this out? Do you work at Sunsynk or Deye?

I agree, the process sucks, especially if you work online from home. We need backups for our backup.

I upgraded my 3Phase 12kW inverter today. Old version: M 2005-1140 / S 18-07 / C 1001-E037 New version: M 2005-1148 / S 18-07 / C 1001-E043 There were no obvious changes to the user interface on the inverter. ---- Also, they said my data logger was already on the latest version, i.e. it hasn’t changed since I manually updated logger firmware in November 2022: Data Logger Hardware version: AEW2-0005-03 Data Logger Firmware version: 4790123B24R

Most likely the latter. Manufacturer likely sends it to suppliers with latest FW but it may be standing in stock for a while before it gets to you. I doubt that shops/suppliers update the FW... Your installer may do so if they're diligent.

Thanks @Bennie Troskie. Your inverter: 5k, 8k, 12k ?

@DeonBez@rob1

Perhaps you could get away with a firmware update on the dongles? I posted a while back how to do that - bit more technical than the inverter upgrade. Let me know if you need the details again.

Interesting that you don't experience an outage during COMM upgrade. 🤷‍♂️ Also interested to hear about your off-grid experience. Is it by choice or is your setup in an area without grid supply? How do you manage during extended cloudy periods @Fred79?

@Jan Blom Do you experience an outage when they upgrade your 12k software? From your statement above it seems you had uninterrupted power during the upgrade. I always experience a short (less than 5min) outage, specifically when the "C" part is upgraded. This time was no different. It's very annoying because you don't know when the upgrade will happen!

@Tarryn AFAIK the official channel is via this form: https://www.sunsynk.org/up-grade But you can also email: [email protected] who is on the update team. They are the person (gender & name unknown) that supplied me with the firmware file for the data logger (attached earlier in this thread), which you have to upgrade manually. Be warned: inverter firmware upgrades, once requested, happen without notice and often result in a few minutes of downtime so plan it carefully and bear in mind that fanyj@ is 6 hours ahead of us. P.S. Please start a new post somewhere to show off your 18 inverter setup. We'd love to see some photos of them and your PV array! I assume this is a commercial not residential setup?

@Milan188 Looking back at the fault codes it seems I've only had that alarm twice: July 20th & July 27 2022. I don't remember what happened at the time or what firmware was loaded. If it was something serious I'm sure I would have remembered the incident. You may as well request an upgrade. I'm currently running: COMM: 1001-E030 MCU: 1123-2005-1807

@ZCS Not that I've noticed. Perhaps just bug-fixes. 🤷‍♂️ Glad to hear your upgrade worked. 👍

No I don't think so. The support guy told me that data logger firm/software can't be upgraded remotely; that's why I asked them for the file. I'll ask again every now and then and will share any upgrade files in this thread.
