Just installed a Sunsynk 8kw inverter DIY and want to share some info.
We use about 1000kwh (units) per month in our house so about 33 per day with about half in the day and half after PV hours. This is about average for a family home I recon in SA.
Already have 2 Solar geysers, gas plates and all lights LED.
I wanted to be independent from the grid as much as possible which weighed heavier than economics although my return is still acceptable and higher after tax than any risk free investment. The whole house runs through the inverter including oven, the solar geyser AC elements, all plugs etc. Only the 4 Aircons is supplied before the inverter but with the Sunsynk CT which fit over the supply line the inverter will push electricity to them too if sufficient PV and battery power are available. I have one normal plug before inverter for if I have to weld or use heavy machinery.
I Installed:
Sunsynk 8kw  Brilliant inverter easy to do DIY and with help from Powerforum posts.
Jinko Mono Cheetah 400w panels * 18 - Connected in 2 series - 9 each. 9 panels in series match perfectly, max voltage around 410V real life in October (Sunsynk specs max 450V) and producing 97% of rated panel watts (3500w per string) max.  Fitted on aluminium rails on tile roof. Fitting the brackets under tiles is quite a job got my son to do that. 6mm PV cable running in PVC conduit from panels to inverter.
One set is facing West and the other facing North. I think if you can get East and west facing panels that is ideal, as you need PV power early in the morning to charge low batteries and then you want to produce as late as possible in the afternoon to have full batteries going into evening. Although not the ideal orientation PV panels are cheaper than additional batteries.
Pylontech US3000 * 5 These batteries when 100% charged at 5pm run the whole house through the night (have about 20 outside lights 3 pc's etc) and start to charge at 6am from west panels on around 30% SOC in October.
By 11:30 am the batteries are normally 100% charged, then I boost the geysers through Geyserwise on free electricity to increase their temperature so that they are still warm in the morning.
PV protection DB with fuses, surge arrestors and DC isolators.
Fuse and isolator between Batteries and Inverter
Grounding ROD and all earth wiring.
AC CB and change over switch etc in AC DB with relay for earth neutral bond
 
Total cost about R 210 000 (ex own labour) except for heavy overcast days I am not using any power from Tshwane, bill was about R1800-R2000 per month.
The feeling when the kettle and iron etc are on during the day and you know that it is not costing you anything (yes i know it is kinda) is priceless.

With regard to the sound of the 8kw inverter. Within 6m you still here it clearly. It switches on and off so no even noice. I will not install it close to me. Spend a little and put it in the garage.

Ok I am going to say it, this is VERY impressive. Hat off to your technical abilities Boubul.
Now if one of you can package this in a consumer friendly way which us non-geeks can understand and use it will be great. Willing to compensate.

Sad that this is degenerated into a mud slinging & pissing match.. Unfortunately having the discussion about Victron/SunSynk etc is misplaced and has detracted from the point. 
This was a battery discussion. Maybe we should stick to that, and go have the measuring contest in a different topic.
Unfortunately while Hubble is clearing following this, its not what I would call constructive forum to answer given the rest of the fluff. (although it does seem Hubble answering selective questions, which is their right, not like Pylon-tech is going to come chat with us). @HubbleLithiumMaybe post the details in the actual product pages or in the post where you shared the installation photo's.
The useful bit I have gathered so far that is that wiring of these stacks( 4/5 bats) is something we should be a little more mindful of. Does anyone have a spec on max current for 25mm^2 vs 50 mm^2.
It is however interesting to note that there is some bias to Hubble for now all three staff picks are Hubble related.....
@Energy-Jason is there any direct links between the forum admin and Hubble? I know the power-forum-store is the official agent for at least the RIOT, any other links that we should know about in the interest of transparency? (I have no issue if so but is good to understand nevertheless).
While I will continue to follow all of these topics as I have invested in the Hubble equipment , once installed I will share my experience.
 
Now back to the actual topic of batteries

I agree

Thx for sharing the training manual, interesting reading. I changed the extension CT cable yesterday to a twisted pair, so far today I did not have any negative Grid power, holding thumbs.
I still get the weird jumps in Grid Power see blue line on graph, (only about 300w for a few minutes, 2 or 3 times a day) My timer is set to 30% SOC on all timers, inverter set to draw 100w from grid and battery is over 60% when this occur with plenty of PV and it does not necessarily happen when consumption is peaking. Anybody getting similar peaks?
Another thing to keep in mind on a new installation is placement of the Inverter, the 3 fans are louder than I expected, I can  hear it from 10m away. It switched on and off but runs when PV or load is running high.

The 3 drums are actually to refill a thirsthy generator on another property of ours. The 700kva generator uses 129l of diesel per hour if running at 100%. Interesting there I have a 428pkw solar installation so once generator is running the solar start to produce again and assist the generator much like possible on small scale with Sunsynk. 

I use either SolarmanPro or Solarman Smart. Both on PC and mobile. I find the smart app is beter for history graphs like to see what was lowest SOC today. And Pro is updating faster and is easier to check current data. 

So far my grid has been completely off so can't comment on transfer time sorry. Batteries are amazing was running a 12000 btu aircon last night for 45 minutes and it only dropped by 4%.

Photo was taken at about 8 am so shade never covers panels during day, even in winter, I made sure of that.  4 strings, 3 in series.  Did the installation myself.
