valienté

I have access to my sunsynk account. Will be enough to check logins etc.
Just a matter of finding time to find a way to do the same in node red.
Main problem is trying to fnd equiv functions in node-red

Seems like it died this morning...



Doing some investigations, manually logging into https://api.sunsynk.net/ there are 2 changes that I am seeing:
URL changed from https://api.sunsynk.net/oauth/token to https://api.sunsynk.net/oauth/token/new
Payload password seems to be some kind of hash:

This hash password changes every time, so using this static value does not work - I suspect we will have to manually calculate the hashed password the same way they do it on the site.

Hi, I love your setup and I do want to build one aswell. Can you please PM me your whatsapp number if possible othereise we can chat on messages. I have a few questions please

I've written a bit of documentation for the capture tool, so while it's still pretty rough, I think it's ready for other people to try it out. See instructions at https://github.com/bmerry/sunsniff, and let me know if you run into difficulties, since that'll help me improve the instructions.

SunSynk 12K Updated - 22 November 2022
Original MCU versions:
M 2004-1108 / S  18-07 / C 1001-E024
New MCU versions:
M 2004-1123 / S  18-07 / C 1001-E030

5KW FW updated yesterday:
 

I was also looking for a solution here
If you have some energy meter (measuring total consumed kWh). You can try the following (I use it in packages\prepaid.yaml). My energy from the grid is measured by the sunsynk inverter, but any meter should work
You can now create an automation if sensor.prepaid_units_left<20 to send you a message etc...
 
# A sensor that indicates how many prepaid units you have left # # 1. Enter the units using "input_test.prepaid_units" # 2. An automation save the sum of the enetered units + grid total # 3. The sensor displays the saved value - the current grid total automation: - id: "prepaid-set-units" alias: Prepaid - set units initial_state: true trigger: - platform: state entity_id: sensor.prepaid_units_left condition: "{{ states('sensor.prepaid_units_left') | float < 0 }}" action: - service: input_text.set_value target: entity_id: input_text.prepaid_units data: value: > {% set units = states('input_text.prepaid_units') | float %} {% set total = states('sensor.ss_total_grid_import') | float %} {{ (units+total) | round(2) }} input_text: prepaid_units: name: Enter Prepaid units from meter pattern: '\d+(\.\d+)?' mode: password icon: mdi:home-lightning-bolt-outline min: 1 max: 10 template: - sensor: - name: "Prepaid units left" icon: mdi:home-lightning-bolt-outline unit_of_measurement: "kWh" state: > {% set units = states('input_text.prepaid_units') | float %} {% set total = states('sensor.ss_total_grid_import') | float %} {% if (units-total) > 999 %}999.999{% else %}{{ (units-total) | round(1) }}{% endif %}  

Was just browsing the Hubble Lithium | AM Series website and saw a Coming Soon section
 
AM-2 PLUS - No info on this   
AM-5 5.12kWh: AM-5 Spec Sheet  
AM-10 10kWh:   AM-10 Spec Sheet  
 

Number of options available - 
If the unit being mounted does not have mounting screw facilities - as per AM2, best to use either the single rack per battery, as listed by system32 or if the batteries are the same size (width) as your rack allowing no horizontal movement, use the mounting angle sleeves.   (Basically right-angle sleeves mounted on vertical rail posts allowing battery to be slipped in.
NB:  Batteries are heavy, thus the choice of rail must be able to accomodate the weight (42kg) 
Listed as;
# Mounting Angle for use with 19"   (Made by Rittal - RS Components)
# Navepoint 1U rackmount 4-post shelf rail (Amazon)

If you use a shelf that's held at front & back you should be able to use any rack that's big enough.

Sides removed to show mounting:


I used these shelves to hold equipment that does not have rack mount holes / rail kit.

Good News,
The firmware upgrade I requested via https://www.sunsynk.org/up-grade has been installed - THANKS
Old Ver. M 6.0.0.9 / C E.4.1.C
New Ver. M 6.0.1.4 / C E.4.2.4
The new firmware seems to have resolved the prioritisation issue as can be seen below:

Thanks powerforum for all for the advice and @Leshen for offers of assistance.
Thanks SunSynk for the prompt service on the firmware update and fixing the issue.

Would be nice if SunSynk published a firmware change log.

If you look at the board and the data-sheet - URL TO PDF - you will see only a few pins are being used...  Should be able to break into the board quite easily by running wireshark and looking at the data coming out of the network...

Is an ESP32 MCU, would be cool to reflash with ESPhome and pull all the data from the inverter that way. 
 

Confirmed

Great choice.
That is because they are basically white-labelled pylontech batteries.
Many seem to have, we know that Hubble has had some claims (and that they were honored). 
If price were no objective (as your thread title suggests) then there is currently no better that the Zenaj Aeon LTO battery. You will probably need 2 or 3 of them, but they boast a 22,000 Cycle life at 1C discharge rate capacity. I am not sure of your age, but that's probably more than your lifetime. 😄
https://zenaji.com/aeon-battery/
They are pricey though, and realistically, considering South Africa's price-sensitive market and weak currency, so you have a choice of Freedom Won, Pylontech, Hubble, Dyness, BYD and BSLBatt (and some others that I haven't mentioned).
I have both Hubble and Pylontech at two different installs, and if I did another install today, I'd probably go for Hubble again. My reasons are many, but a 1C battery being locally supported with a good track record speaks volumes. I'd also consider BSLBatt (another 1C contender) and BYD, depending on price performance.
As all of the available batteries are pretty much new, testing of 10 year warranties isn't possible today. The closest you will get is the testing conducted in Australia https://batterytestcentre.com.au/   

This is a gold mine of information. Thank you all for the posts and sharing knowledge.
I'll add my integration for loadsh*tting and managing my devices during these times.
First a grid check sensor in Home Assistant. Add to sensor.yaml or similar under sensors.

It will also send a notification to the household phones via Telegram and Home assistant app when load shedding starts and ends.
It also checks the inverter load during load shedding for high usage if another device is using too much power and notify me.
Lastly, the kitchen LED lights is changed to RED even during the day, to remind said household that load shedding is active. 😜 Done via 2 automations in Home Assistant.

RS485 CAN HAT for Raspberry Pi | Lost Distance Comm’s (diyelectronics.co.za)
 
Only 17 remaining...

I am using the JaSolar 540 watt panels and the current rating is 12.97 amps, the Sunsynk 5 kW can handle 13 amps with a firmware upgrade, have seen 12.97 amps briefly and above 12 amps quite a few times

You can use this guide for strings calculations:
https://unboundsolar.com/blog/string-sizing-guide
However, keep in mind the max current per MPPT because the formulas, don't account for it.

I have two Growatt inverters inside a cupboard and I have no problems with high temperatures. The temperatures are measured directly from the inverters as well as the ambient temp, never went past 35 degrees C . See screen shot of the last 2 days values. 

Our 12kw Sunsynk is in a cupboard and does not get past 33 degrees. Made ventilation holes in top of cupboard for air to escape into celing and vents at bottom of cupboard doors to suck in cooler air. Cupboard is inside house so much cooler than say our garage. 
I guess our inverter runs cooler as it does not work close to it's max capacity. Also in the cupboard are 3 hubble batteries 
I attached 2 fotos

Update:
After 6 hours, this is where we are at. The power cables to and from the DB is already in the ceiling as well. Invertor will be properly attached to the wall this morning
