This is mine. Just took a piece of alu flat bar and bent the one end 90 degrees and bolted the other end at the fan side to the 3d printed fad mod. So it just hooks over the inverter.

Both temps dropped by between 10-15 degrees. My ambient temp in the garage never goes above 15 degrees.

I had an Efergy unit installed in my DB for 2 years before I got my solar system installed. That data is worth gold. When the time came for solar the decision was easy. Could see exactly what my peaks were, and when. And also how much electricity I consumed per day, week, month, year, etc. Winter and Summer etc.
If an installer wants to impress me he must suggest to me that we install a device like the Efergy for at least a month to get some hard data. If you can get such a device, get one and install it asap. The sooner the better. 
All of that data can then be exported to Excel or google sheets and you can play around with it and make it more user-friendly to tell you exactly what is going on. Priceless.
Just going on how many units you use per month is pointless. I mean those units can be mostly used at night for instance and you don't know. You cannot make an informed decision based just on that.

Fsckers, they use PBMTools themselves. When I had a faulty cell with SOC issues I told them the one battery shows lower SOC in PBMSTools.
They tuned me to please refrain from using it. When I took my battery in to Hubble JHB they used PBMSTools right in front of me and showed me the faulty cell.
 

I am cured of FW upgrades after my experience.

Great post thank you. If one is still of another opinion after your post then IDFK.

In the highlighted text, I assume you referring to the OP's issue where SunSynk broke the inverter by installing 5k firmware on a 8k inverter.
I fail to see how this can be anything but 100% SunSynk's fault.
I would expect SunSynk to go the extra mile (as it's 100% their fault) to resolve the issue promptly without inconvenience or cost to the customer.
In terms of your other comments wrt to isolating the inverter for a firmware update (no load and no PV)

Most of the forum members would agree that If an inverter malfunctions during firmware upgraded when it's not in bypass - that's 100% SynSynk/Deye fault

Because:
a) the official SynSynk link for upgrades does not state that the inverter needs to be in bypass.
https://www.sunsynk.org/up-grade

b) the official SynSynk user / installer manual does not state that the inverter needs to be in bypass.
https://www.sunsynk.org/documents/
Sunsynk_Hybrid_Inverter_8kW_UserManual_v24_English.pdf
c) the official SynSynk training manuals does not state that the inverter needs to be in bypass.
https://www.sunsynk.org/post/training-manuals
Part 1 Training Manual Sunsynk - HQ.pdf
Part 2 Training Manual Sunsynk - HQ.pdf
e) the official SynSynk training videos (and there are many and I've watched most of them) does not state that the inverter needs to be in bypass.
https://www.youtube.com/@sunsynk5885

f) The official SynSynk technician actually doing the firmware update should check if the inverter is in bypass.
(They should definitely check that the firmware is correct for the model inverter)

g) It is not practical to put the inverter in bypass and just wait... and wait... and wait... 12h, 24h, 48h and hope that the update gets done remotely when SunSynk decides they have time.

h) The Sengen Application Note you link to states "Sunsynk will perform an update, this will reset the inverter. Ensure you are not supplying loads with the
inverter."
The way I interpret the statement is "the inverter will reset during the firmware update process and if you are supplying loads these will go off so bypass to prevent your loads being impacted"
I work in IT and have done plenty of firmware updates in my career - computers, routers, printers, cameras, storage arrays, disk drives, network switches, CPU microcode, HBAs, NICs, RAID Controllers, motherboards, fabric switches, firewalls, phones, DRACs, iLOMS, etc.
The first thing you check is that the firmware is for that model hardware or else you end up "bricking" the device.
Most newer update systems and firmware will auto-check compatibility first and not allow invalid updates.
SunSynk was released in "newer" age but still uses "older" design of not auto-checking.
Q. When is SunSynk going to provide firmware change logs to installers & public?

I am cured of FW upgrades after my experience.

Ja no look. AFAIK it is not mentioned on the page where one requests the FW upgrade. 100% off this on the guys at Sunsynk. Now he has to deal with the unknown time frame for repairs. That was not his fault. Not sure where you're coming from with your stance on this.🤔
And anyway it does not matter if there was a load or not. They flashed the wrong FW.  They can get fscked.

I would agree with this IF the user downloaded the software themselves, plugged in a network cable then proceeded to do the install - there is inherent risk there. But the outline clearly shows the processes were performed by someone from sunsynk - so the risk is all on them and sunsynk as a company. I think OP is well within their rights because they followed the published process and it resulted in a broken device - something that can (and has) happened to any of us (@WAP) included
 

If this is their requirement, this should be publicized way better and not on 3rd party website and distributors.
I wonder why they don't have a button on the inverter it's self that just says "UPDATE NOW"?
Then a prompt stating "ARE YOU IN BYPASS MODE"?
"OK"---- update completed.

This is the one I have. Price was around R600 IIRC. Got it from my local Battery Centre, the guy does solar installations as well.
My installer installed the unit. If you google a bit you can find a few variations of the same thing.

I got one similar to this installed in the DB. It has proven itself a couple of times already. You set the parameters and it cuts the eskom feed if the incoming voltages are below or above your settings.

I just send my garden engineer up once a month to spray them down and clean them with plain water and a window washing thing like so.

No, fsck them! The cloudlink has zero use for the end user. They tried to fix my battery via the cloudlink and i had to take the battery in to them at the end.
The cloudlink won't fix anything. That is by itself. It just allows them to connect to the battery and change parameters. So they "might" be able to fix something. 
I also have a synsynk and hubble system at my fathers place that always charges to only 97-98% and i have done everything i could with hubble support and via the cloudlink. Still no fix. I just gave up and left it runing like that.
