Hi @Coulomb
Post updating my firmware (you would have seen my process I used in this thread), I beleve this has resolved my issue with the MPPT Dropping.
The main cpu firmware has changed from 68.03 to 68.11

Feedback on the attempt to update my TheSunPays 4KW inverter using the recources that @Coulomb Suggested.
I disconnected my inverter from the Grid, output load and solar therefore only running on battery. Connected the inverter with the RS232 cable, started up the Reflash tool, selected the approriate COM port and clicked update, I heard a click from the inverter, after about 2 /3 mins the reflash tool reported a connect failed.
The inverter was non responsive from the front panel, after a complete powerdown and start up, it was back to working. I tried a few different com ports (1/2/7) with the same result. I am guessing this failure is due to there being no bootloader as Coulomb suggested.

That is all

Yeah sure not problems. please see the screen shots below.
I need to run my geyser twice a day for 1 1/2 hours to get a nice hot morning shower and bath for the young-one in the evening.
It consists of 3 rules, two the turn on the geyser one morning one afternoon and one to turn it off after 1 1/2 hours. I'll post the afternoon example and the turn off automation's.
The "turn on" consists of two triggers, one for 4 pm if there is no LS or 1 1/2 hours before LS starts (this is a calendar event that is created by the ESkomsepush's integration)

For the Condition and action there is one each as per below.

Turning the geyser off is pretty simple.

Let me know if you have any other questions.

Hey Guys so its that time of the year again and we have a whole Host of Giveaways lined up some to watch out for would be the New Solis S6 6KW Advanced Hybrid (Beast) we are busy with a long term review in real world conditions with the Solis S6 the Unit we are giving away has already gone through a preliminary review but we may give more of this brand away in the future. 
Magneto has given us some wonderful product to review and give away MAGNETO Lithium-LiFePo4 Rack Mount 48V 5.1 KWh also note the great prices on those units  and a  Magneto Thermo Tank also promise of more nice items to give away in the future. 
Then we Have the Revo Inverter and battery Combo (not listed on our online store yet but soon) there will be some terms and conditions on this giveaway however an exciting product squarely aimed at Sunsynk and Deye.
We are also receiving a very nice Battery from Halo Energy to give away the 113AH HALO Eclipse WM-5 48V 1C however this will only be in about 5 Weeks time but still a very nice compact battery.  
Power2SA is giving us one of their VTC Vxl5100W 5.1kWh LifePo4 battery 51V/100Ah Rack Mount to review and test this is also a very nice rack mount battery with Bluetooth and WIFI features decent cycle count compatibility and scalability and we will give this away to a lucky forum member. 

Man I love this so much, thanks again slipx

HI. The card can be configured to display two non-essential loads but at the moment there is no option to customise the icon under this condition.

Include your two CBI sensors that provide your power info under entities in the card configuration
non_essential_load1: non_essential_load2: If you get stuck head over to the github site where all the options are documented

v1.7.6
Updates
Introduces a new optional nonessential_icon: attribute under the grid card configuration to change the non-essential image. Options are default, oven, boiler, charger, pump If you need other icons please open a request on GitHub Code refactoring

Good luck! There's nothing more satisfying than seeing things "just work".
For the hardware, it doesn't have to be anything special but don't run HA off an SD card. I also recommend running Home Assistant OS. It simplifies a lot.
When you get your hands dirty, take some time to RTFM. I went in with the curse of knowledge assuming how things would work and lost a lot of time redoing stuff. There are also loads of great add ons and integrations that do the bulk of the heavy lifting.

done... would love to peep the data/analysis once use closed it

Fyi, I have managed to build quite a nice front end layout using the sunsync interface that @slipx on this forum setup:
Details on this post

Hi Schnavel
There is no value called TotalPVWatts I used: ICC-Master/Inverter1/MPPT1_Watts

 
 

Hey Duke
You could also reserve the IP for a specific mac address for both your HA and SA on your router?

I am busy working on an update, the powerflow card has gone through so many updates, I need to catch up with those, I also found a bug in one of the automations, not sure if they changed something in the jinja2 scripting.
Please provide some feedback. What seems obvious to me might be confusing to others so I would gladly improve the project/documentation
 

Hmm this is interesting. My mum has an 8KW Sunsync and I need to setup some automation for various things. I'll take a look your setup and see if it works for me

Updates v1.4.9
Better handling of battery attributes with 0 value An optional entity can be added to the card remaining_solar: to display the remaining daily solar forecast energy. You can use the default HA sensor sensor.energy_production_today_remaining or other integrations like solcast to provide the information once setup

This is great thanks guys, Wow I was expecting a 1 to 3 % losses as acceptable but .2% is practically nothing.
Now that it works I need to figure out mounting, but considering that the JA Solar is 2279mm * 1134mm and the Longi is 2278mm * 1134mm they are essentially the same size. I guess mounting holes can be drill if strictly necessary.

So after the change, I can see the the average 100% SOC voltage it now hovering at about 53.8V rather than 53.6V. See below my professional report.

Ok sure. Here goes. This assumes you know some basic linux. If not maybe this is not for you but perhaps I can help if needed:
1) Make sure your Sunsynk connect App is working and you know your username/password.
2) Make sure your Sonoff switches are working in the Ewelink app and you know your username/password.
3) Fire up an Ubuntu VM on AWS/Azure/GCP or even on a Pi or home PC. It can be really small like 512MB RAM and needs internet access
4) Install docker in the linux vm. Follow something like this: https://kinsta.com/blog/install-docker-ubuntu/
5) Someone wrote a nodejs gateway to mimic the calls done by the Ewelink App see: https://github.com/DoganM95/Ewelink-Rest-Api-Server I leverage this as a way to control the Sonoff Switches. To run this listening on port 8089 run this. It needs your Ewelink username/password you registered in the App so it can call into Ewelink servers: 
docker run -d --restart=always -p 8089:3000 -e "EWELINK_USERNAME=yourusername" -e "EWELINK_PASSWORD=yourpassword" -e "EWELINK_REGION=eu" -e "PASSWORD_HASHING_ALGORITHM=sha512" -e "SERVER_MODE=prod" doganm95/ewelink-rest-api-server 6) Test you can turn a switch on like this (Replace "Your Switch Name" with the switch name as it appears in the Ewelink App):
curl -m20 -sX POST "http://localhost:8089" -H "content-type: application/json" -d"{\"devicenameincludes\":[\"Your Switch Name\"],\"params\":{\"switch\":\"on\"}}" 7) Install a json parser utility:
sudo apt install jq 8. In your home folder add the attached script.sh and make it executable with chmod +x ./script.sh
9) In the script set your Sunsynk connect username and password on rows 4 & 5 for SUNSYNK_USER and SUNSYNK_PASS. Then set SUNSYNK_PLANT on row 6 with the plant ID you see if you login to sunsynk connect in your browser. E.g. mine is 88663:

9) Create a cron schedule to run the script every 5 minutes: crontab -e -> then add a row like this: */5 * * * * /home/ubuntu/script.sh >> /home/ubuntu/solar.log
10) Edit the script to suit your needs and refer to your Sonoff switch names. I've got a simple example of a switch called "My Switch" that will turn on if we have excess power and Off if we don't. If you don't know what going on, ping me with your switch names and basic rules and I can help. You have a huge amount of control. I have some fairly complex rules around hour of day etc.
11) To see what the script is doing, run tail -f /home/ubuntu/solar.log
 
I'd love it if this is useful to anyone so let me know if you need help and add any things I might have missed to make the instructions foolproof. My script generates a basic HTML page of the current status but I deleted that part as it just makes the script more complex than necessary. Anyone with basic bash scripting can go wild. If you comfortable with python or something else then use that - its really just some HTTP GET and POST commands surrounded with JSON parsing.

Hi Guys
So I have been running my AM2 for about a year in the recommended (from the Manual and the side of the battery) at 53.6V. So far so good, battery charged to 100% according to the BMS every time.
Now I have increase the bulk and float charges to 53.8V for some sweet .2V extra juice. Will monitor how it goes but not expecting any difference.

As for the Capacity as you can see these my one is rated at 106.1 Ah. I wonder if @HubbleLithium recommends a firmware update?

So in summary, on a normal day like today, with lots of sunshine:

Some things to note:
Not sure what that 01h00 spike is. Need to figure that one out.  The 04h30 geyser boost took place, and pulled from the batteries because the grid was off. This is not ideal, a cooler shower is preferable imo, but there is no way for me to avoid this, unless I wake up at 04h30 to switch off the geyser. Batteries were fully charged by 10h30. The coffee machine morning spike came from the grid, because the batteries were <50% SOC at this time, so the inverter did not allow it to go lower.  The spikes you see above the geyser's 2kW draw include the dishwasher, washing machine and other things like kettles.  15h50 spike was the airfryer, lunch. On a less than nice day, where it's either raining the whole day or cloudy, things might look like this:

Notes:
Geyser still comes on in it's given time slot (hot showers are important!), but now the inverter uses a blend of solar and grid to do that, because there is not enough PV do it alone. The inverter brings the battery up to 75% as per my settings, and uses grid in this time to power other loads. Once it's at 75% it stays there, and uses grid to power my loads, as I had a massive rain storm at this time and PV was uncerperforming. In the late afternoon, the sun came out, and topped my batteries up to 100%. We decide to cook something in the oven at 1730, and the batteries crashed back down to 75%, and the inverter held it there till 20h, using grid during this time.

Somebody sneaking a hot drink in the wee hours? 

You're quite correct; my bad. Here is my block diagram to cover most of the Axpert models:

Ignore the red part (for Axpert King only) and the blue lettering and line (for 145 V max MPPT only). But since the max PV is say 4 kW and the inverter can handle 5 kW, the inverter isn't in a place where it will be the bottleneck.
Let's say there is a 6 kW load, and 2 kW of PV. The inverter is rated at 5 kW, so it is forced into line mode, so the top switch is closed. So power can flow from the AC-in to the AC-out. But in SUB mode, the other switch would also be on, so that PV power can flow to the load as well. The inverter can't handle all the load, but it doesn't have to; the AC-in is there to supply part of the load. So 4 kW will come from AC-in, blending with 2 kW from the PV, to provide 6 kW to the load. The inverter only carries the PV-supplied portion of the load.
It's possible for part of the PV power to charge the battery, via the bidirectional DC-DC converter (at right). In that case, less power supports the load, obviously.

Yes. I used to do this myself.
Yes. It will draw power from the extra panels even when the battery isn't full, in preference to drawing the battery down.
Well there is the cost and installation of the extra gear, of course. The niggle I found is that the inverter sometimes got a bit confused near the end of the absorb stage. But you can avoid that problem by setting the absorb voltage setting for the external MPPT just a little lower than the inverter's. Adjust a little if the calibrations aren't perfect. That way, the external MPPT helps most of the time, just not at the very end of the charge, but then the battery current is low anyway.
I even had my monitoring system (written 99% by a colleague) figure out what power must be coming from the external MPPT, and graph that separately from the inverter's charge power. It got that wrong when the loads changed sharply, but most of the time it worked really well.
I only changed the system when I found I needed more power, so I added another inverter in parallel, and that had another MPPT. So I just swapped the panels to the new inverter.
