@JaseZA,
Yes, that (RS-485) port is available, but it only spews out Inverter Data. The Battery Data it does provide is an aggregated view from the Inverter perspective, so pretty much useless. SA does it a bit better, with the appropriate USB/RS-232 cable, but it is very limited in what it does display. The Battery spews out a lot more info of value than what SA provides back to the user. Make no mistake, SA is very useful, but it is very limited in how/what it displays information, with very little customization possible.
This is why I use the SmartDeyeDongle (RS-485) with HA, with USB/RS-232 cable to the (master) battery, so I can see what I want/need. 

Does anybody have any experience with Greenrich up5000 batteries?
Greenrich UP5000 (4.96Kwh）Lithium-Iron Battery

Thanks for all the feedback!

Don't consider a panel with anything over 12.9A Isc, the 5k Sunsynk will clip it and you will lose PV power potential. Also 125V is barely workable, for optimal power you need something closer to 370V (or at least between 240 and 370VDC).
Rather give Steve a call at the Powerforumstore, he can spec you a budget friendly system that will work well. 

Yes!

I have the BLSB, The deal was 29k for a 6.2kw, but in hindsight the Hubble gets installed by Leshen, and with this will be the @leshen support, and he has a 10 out of 10 rating. On the BLSB I was on my own, was dropped off on the paving, it did not even come with a manual, and calling the support number was very disappointing, but its a great battery, just, you are on you own.There was going to be a charge for installation, cables, fuses etc, on top of the battery purchase. Since then I have been given a copy of the install. Its got the cable sizes and some sunsynk setting, however no mention of much else. Like I want to know the best install location. Vertically or Horizontal, Is there a cabinet available, Is there rails? How many are supported in a single location and probably more questions i dont know yet. Whats the support if there are problems??

This is what having a battery looks like. this was around 830pm. My self usage on this Sunsynk after setting up solarman and monitoring three days so far - 95 percent self usage. In other words my usage from city power is 5 percent when either battery or PV are not able to support the installation. Thats allowing the Sunsynk to use essential and non essential load. My essential is low as per my diagram. Fridge, deep freeze , house plugs, lights etc. non essential has the high power Amps. Geyser, pool pump, borehole, oven, garrage.

LOL, Hope it has not scared you off!!!.  You know how exciting it was when you get your Sunsynk working??? You watch the panel and it shows you the usage from the solar panels, the battery , from the grid, Its so neat. You see the CT between grid and your house, and it shows  you 40w grid usage. (I set mine to no export back to grid 40w) I mean its drawing a LED (40W) from the grid. The whole house is supplied from the Sunsynk, WOW how amazing is that.  Then you really appreciate what a awesome inverter and battery you have. Keep well, Feel free to ask, these people are good people.

The battery settings on the Sunsync are really really great. I tell our sunsynk, my battery usage, Use for load only, or use load and non essential, but dont use more than 50 percent at say 21:00, ohh and when you do,  dont use more than 3000w , why? Well I only installed a 125A fuse when I should have a 160A or 200A (Again not knowing better) and 3000w maximum at night only , it is well well within that A. The Sunsync has many settings that help you control the battery usage. I dont understand them all yet, but you can certainly use a smaller battery and control the use of the  battery in a controlled manner, that no battery company should not honour the warrentee. If they document properly , and say, dont DOD less that 50 percent or dont draw more power than 80A but Ideal is 75A or charge slower than 75A,again, If they document properly, all these setting are possible. Why I did not buy Pylontech!!, they dont have a good warrentee reputation. Although I have learned since then, its also who supplied it. I could not find out who actually is the official agent. Thats very private.

Stretch your budget a little bit and get two Pylontech US2000B for R23k at the Powerforum store and you will not have to worry about warranty issues.

Only seeing that now, new ones are now relatively cheap. Going for R11k6 😃

It's a scam.

I am running a single US3000c on a 5kw Sunsynk atm , if you only have small loads to run its fine.(fridges, lights,computers )I run 4 fridges ,4 pc's and a few lights and it pulls about 700w . Just make sure you set the max charge /discharge to 37 Amps for the battery, and when there is loadshedding make sure not to load up more than 1,8kw. Alternative would be to get the Hubble AM2 but if u dont have the money u dont ...
 

You can try removing the graphics card, these are notoriously power hungry, rather use processor's onboard graphics or downgrade to a smaller entry-level card, and then fiddling with the power save settings. Best to replace with a smaller machine though, I use a 8th gen HP Microsever 24/7, it uses 50W (max when starting up) and then settles down to a trickle. despite having 4x 4TB drives, It also doubles as a Unifi controller and Pi-hole runs in a container. Second-hand ones are cheapish and pretty common on Carbonite.
I also replaced my desktop-based firewall with one of these, works great and runs a full UTM. Next on my optimisation list is my 16 port switch, will keep my eyes open for an energy efficient one that supports PoE. 
+1 for 5.5k Sunsynk, love mine, works great.
