Will report back when done - only inspected yesterday afternoon.

Well, I hope this is going to help someone in future. YellowTapemeasure (is it Stanley? 😁), LiBMS screen showed normal and proper comms with battery. CAN cable connected to master inverter only. Parallel cable between inverters. All good. Even tested continuity.
Performed manual reset on Hubble by discharging to less than 10% SOC (set in AGM V mode), then charging up again to realign voltage markers with BMS. After this procedure, tested again but charge rate still limited to around 20A or just over 1kW. The BMS current limitation shows 150A - all good, That's what this battery is supposed to be able to handle. Many hours of frustration and a call to Hubble's technical support desk - I decided to check the pinout on the specially made up battery cable. For the AM-10 and Sunsynk pins 2,4&5 are used. Opened the inverter and checked the plug. All good. Pins 2,4&5 - check. Even more frustration. Thought to myself I wasted a trip to site to check a damn cable and there's nothing wrong with it. Just for entertainment purposes, I decided to edulge the very friendly dog and go and lie on my back to check the battery side plug too. It was dark and with an all too friendly and excited dog all over me, pulled the plug and squinted at the pinout. Something looked odd. Could it be? Grabbed the phone for more light - really?? Got up and grabbed the number two reading glasses... Dog got very excited to see me lie flat on the floor again. True as nuts - the battery plug had a different pinout to the inverter.
Just for reference, some inverter battery pinouts have to be different, sometimes even crossed over. The Sunsynk 5kW and Hubble AM-10 however requires a straight through 2, 4 & 5 pinout. Mine was not that...
It turned out that a specially ordered cable was either made wrong or the wrong cable was supplied (albeit marked for Sunsynk/Hubble).
Made up a new cable, plugged it in and went home (loadshedding in progress). When loadshedding ended I was very disappointed to see the same symptoms - slow charge rate. I was so hopeful that the cable was the issue. I then decided to do a remote factory reset once more and re programmed the settings.
The system came online and low and behold, the charge rate picked up, and up, and up! With bated breath I watched the charge power tick up to 5kW, and it settled there, and remained there till the battery was full. I could not believe it. Three days of frustration was over. A simple little thing that was overlooked, and never suspected since we had proper readings on the LiBMS screen.
Goes to show - If your system does funny things, check everything, especially the basics.
 

Nope - not gonna leave this alone:
Section 41 of the Consumer Protection Act, 2008.

Think I'll opt for the "product as marketed"....

they take 0.75C of 150A

OK, so I got feedback from Hubble, and it is not good. Just for reference, this is what the AM10 specs says, as well as the specs advertised on Segen's website:
From Hubble:
Rated Capacity (5HR): 200Ah 
Nominal Voltage: 51.2V 
Design Capacity: 10KWH 
Equalized Charge Voltage: 55.2V 
Max. Continuous Charging Current: 150A 
Max. Continuous Discharging Current: 150A 
 
From Segen:
Weight:
99 kg
Battery Type:
Lithium Ion
Nominal Energy:
10240 Wh
Depth of discharge:
100.00 %
Voltage:
48 V
Continuous Discharge Rate (Normal Use):
7680 W
Maximum Discharge Rate (5 Minutes):
7680 W
Surge Discharge Rate (15 Seconds):
7680 W
Maximum Charge Rate (5 Minutes):
7680 W
 
Hubble now have confirmed that the battery cannot supply 150A continuous and can only do 112A (0,75C). Although their datasheet explicitly states MAX CONTINUOUS CURRENT 150A, this is a lie and now I have a customer who cannot use the full potential (or even close) of his backup system.
This is false advertising and sell batteries which cannot meet their published specs. Also, Segen states 100% DOD but in the Hubble manual it says only 80% DOD, so which one is it?
Be aware.
 

Nope, don't know a Stanley 😃
I am glad that you got it sorted though, and thanks for sharing the issue, we can all learn plenty from it. What's interesting is that despite the LiBMS screen displaying correct values, it still throttled the inverter's charge rate. This is where a Cloudlink may be somewhat useful, but a proper sniffer like wireshark would definitely show it up. I should make up a dongle with 3 RJ-45 ports so that it can be used for future troubleshooting.

Indeed.
Induna, I would try the remote factory reset. It helped in our case. Also, ask your client to double check the can cable pin-outs please. We assumed it as being correct since it was supplied for the Sunsynk/Hubble pairing - but alas...
Should be as follows for the AM-10.

Feedback almost 7 months since start-up.
I am so happy with this system - especially now with the load shedding. Some may say I had inside information...
Have since added a few smart switches, re-kindled our underfloor heating system, threw out the original WiFi data sticks and bought the Sunsynk data sticks (still not 100% happy with servers going down every now and again - although so much better than the Solarman app. Thinking about the Raspberry Pi option for real time data. Happy users out there? Any recommendations? Oh, and converted to pre-paid to save on the network and surcharge garbage.
We have not seen one day without power to run the full household - including geyser and air conditioning - what a pleasure it has been so far!
April saw a LOT of rain in Joburg and there were more than the usual number of days where I had to manage the charging of the battery very carefully.  Nonetheless, our grid usage is next to nothing. More a case of me preserving the SOC at above 35% instead of 20% to be honest. I want this system to last till I sell the property - and beyond.
Below a few energy generation graphs of the system.
Thank you to all who so kindly contributed with knowledge.
This is a wonderful forum.
 

This is so much fun to watch as it's happening. SOC up to 75% at 11:00 after draining to 36% overnight.
Current rate of charge: 7.6kW
Production: 8.02kW (My panels are at 40° - Should be at maximum efficiency in June / July. Quite happy with a summer day yield so far)
Consumption: 278W
Grid feed in: 89W.
Can live with this.

The finished plant in the garage.

Almost there!
2 x 300mm² Busbars for battery connections behind backing board.
DC wiring done. A/C wiring next up.
I'm thinking to wire from the "load" connection in the inverter (essential power) straight into my house DB i.e. everything will be on essential load - with a changeover switch to grid supply if battery power is low. If I utilise the grid connection with CT coil on incoming live with zero eport set, the battery would charge via mains right? Not sure I want that to happen.
Any advise would be welcomed please. I'm uneasy with what to do next to be honest. Island (with changeover) / hybrid.

Good evening from a new member.
So, the journey has started for us too. Our roof faces 12° West of North and a slope of 40°. Split level. I planned the roof layout on Cad and started the painstakingly slow process of attaching the hooks to the trusses. Using the Variosole railing system. Due to the slope of the roof I had to be very careful to prevent ending up in hospital with a broken something. After two weeks of working for an hour or two after work it was done. Those huge PV panels were glaring at me from a distance. I devised a lifting & sliding mechanism with a rope on a pulley to hoist then pull the panels up against the roof. (I am doing all this alone - so it's up and down the ladder 10 times per panel...) At 51 years of age your body feels the aches after a while.... The panel installation went smoothly - took another week or so to get them all up. I reticulated the wiring in Bosal conduit fixed to the railing. 4 strings, 8 & 6 panels grouping x 2. The reason for the unequal numbers due to expected shading on part of the roof. I decided to group the shaded panels in the two sets with 6 panels each. When I was about 3/4 done with the larger roof section I noticed the panels are slightly miss aligned and are dropping off on one side. I had to work from one side and do both rows in one go due to the slope. When all the panels were up I had to go back and do adjustments to align properly. I could not face looking at skew panels every day. (I have been told that I do need to seek professional help for my problem and I will - but only when I'm finished and happy....)
I have now reached the point of mounting the electrical equipment and switchgear in the garage - and hence registering on this forum. I am not an electrician. I do however intend to install this system so that any worthy electrician will be envious. The equipment layout has been planned and I'm busy putting up the P8200 trunking to house the wiring. There will be two ducts alongside each other to split A/C & D/C cables.
I have a few questions and I am sure as I go along more questions will come up. I'm hoping some of you friendly folks will be able to assist with your experience and knowledge and help a mechanical man with electrical know-how please?
I will be connecting the two 5.5kW hybrid inverters in parallel to give us 11kW. I have read the training manual and watched Keith Gough's training videos. There is so little good technical literature out there! I find it frustrating sometimes. Anyways - The freedomwon battery has 4 power cables. Would I be assuming correct that after the inverters are connected in parallel that I can wire one set of cables to each inverter? I do realise this is a  stupid question - (and there will be many more!) I just want to make 100% sure that what I'm doing is right. Would really appreciate your feedback and tolerance for all the dumb questions that will follow. Oh, and if someone needs advice on how to install man alone against a steep slope - I can offer my experience and share pics of the devices I made to help make it easier.
Below a few sketches of the planning phase and how it turned out eventually. (Still need to make some alignment adjustments on the bottom row). Rest of the work is now in the garage.

You're not the first person who say that....🥴

She's alive! 😀 (and working it appears)...
Only figured out late this afternoon that you have to set the time function in order make the system operate from the battery power.
Also received an email from freedomwon today - I invited them to free and verify the installation / commission for their warranty clauses to be validated. Apparently they don't do that. They will however put me in touch with an accredited installer in my area. Looking forward to test the guys knowledge. Have soooo many questions....
Anyways, just finished a reasonably heavy evening with the washing machine, stove, a/c and geyser on. Total draw approximately 7kW at one stage. System seems to cope well.
Looking forward to see the pv yield tomorrow.
