Hi @TheRoDent, I double checked and it was off for some reason. Switched it on and all the info showed up. Thank you very much.

Did you enable the "Discovery" checkbox as per the manual ?

Whilst it would be great to get this going, as a home-brew, I just took the plunge and installed @SolarAssistant on a Raspberry Pi, with a USB-RS232 adapter.
 
Simplest, easiest integration I've ever done, and solarassistant.io is superbly slick. Well done.
I now have a useless Sunsynk Data Logger, which I shall attempt to brick at my own leisure using ESPHome.
 

This worked perfectly for me too. The instructions received from Segen Solar for their unit is entirely incorrect regarding numbering of the terminals and how to connect it.

So, after several weeks of planning, and getting the basic gear from mecerinverter.co.za, and a bit of a hackathon this weekend, I'm finally starting to disconnect from the grid. Well, becoming less dependant on it, shall we say.
Ordered a 5kw Mecer Axpert King, and 3 x Pylontech US3000's from Devan @ EnwayPower/MecerInvert.co.za
My order was fulfilled within 2 days, and Devan is definately highly recommened. Their google star ratings show it, and I was happy to give them a 5 star rating too. In fact my colleague ordered the day after me, and was also fulfilled in 2 days.
As it goes in the current economic climate, and budget constraints, my plan was to first just get rid of loadshedding, so --basically I have an inverter, and 3 x Pylontech US3000's setup just to avoid having to run outside to startup the portable generator during loadshedding (which I installed around 2008 with the firsrt loadshedding bouts).
My general critical load including fridges, TV's, a boatload of PC's, TV's and some lights and plugs is generally around 1200watt. I split my DB board for the critical load back in the generator days.
I used surfix 2.5mm rated at 23Amps for connecting the mains feed to the Axpert King, as well as back to the critical load DB. I put the surfix inside PVC conduit as well, as it's easier to manage/get straight (Yes, a bit OCD). I used some basic 20Amp breakers to protect the Surfix  wires from my City Power feed, to the Axpert and from the Axpert to the critical load DB. When I redo the main DB I'll add some changeover switches to be able to augment City Power with the generator, but for now, the generator is out of the loop. I'm loathe to reconnect it until I've confirmed what I can do about the potential VOV situation and earthing issues. I haven't installed any DC fuses yet between the batteries and the inverter yet, but that's next. 
The Axpert didn't want to communicate with the Pylontech batteries using the supplied cable, so I went through the firmware upgrade process via USB On-The-Go, and a flash drive. Bricked the unit when I thought the upgrade had hung, then booted back up into Error Code 32, nothing else showing. Used the USB OTGagain, and realized finally that the upgrade does take some time. Simply press the OTG button a couple of times until the upgrade option show again (Had a bit of a freakout).
The inverter came with a BMS (RS485) cable for the batteries, but the pinouts were simpply straight-thru. After some digging on these forums (thanks guys!) I recrimped the RJ45 to create a crossover cable, and eventually with the 71.86 firmware flashed, and the proper pinned out RJ45 cable, the batteries and the inverter were talking.
Then cabled everything up, and working now on batteries or mains, depending on the AC input.
I've also ordered ICC software for my Raspberry PI2, and am busy flashing it as we speak. Thanks for this great local product, and happy to support local dev's and expertise!
I really want to thank everyone on this forum for sharing their experiences, and creating such a body of knowledge which is google-able, and for everyone taking the time to answer questions. It really reminds me of the old days of MyBroadband.co.za.
The next steps for me would be to get a PV array up, convert some of my geysers to GeyserWise with DC/AC elements and panels, as well as a smaller inverter setup for my fishpond.
Soon, I will be able to cut the cord entirely, and keep a basic prepaid City Power service available in case of emergency.
Herewith some PIC's, and once again thanks to people like @Coulomb and numerous others that makes this such a great forum.

Hi @TheRoDent if the supply from the utility is multi-phase and the multi-phase supply is broken down into single phase supplies then it is fine with only an earth leakage per phase, as long as the load is only a single phase load.
If the load is a multi-phase load and the load has bare metal exposed where one might get an electric shock if there is an electric fault on the load then there must be a multi-phase earth leakage installed for the multi-phase load as well.
Usually what they do in multi-phase installations is they split the incoming supply from the utility up with 5 bus-bars 3P+N+E and from there they supply 4 earth leakages 1 3P+N and 3 1P+N all wired in parallel, if you wire the earth leakages in series and there is an earth fault then the 1 with the lowest earth fault current will trip first which might be annoying and or problematic.
Your setup is correct because each of your single phase DB's are protected by a single phase earth leakage.
