Don't want to lead you the wrong way, but I think there are many people using SA with this inverter and it's different models. I'm using an older Raspberry Pi not the 'official one' you have but ...
I think the issue you had was just because that was a bad/reconditioned inverter....

Thanks @Kenny_ for making a fuss with customer support about comms cables, must have been the hold up on beacons replacement ?

EG4 LifePower4 batteries actually have two RS485 (modbus) serial busses (as well as a CAN bus).
Pins 1 and 2 (orange/white and orange, normal ethernet) form one bus.
Pins 7 & 8 (brown/white and brown, normal ethernet) form the second bus.
If using the EG4 Communications hub:
The hub polls the batteries on pins 7 and 8. Any other communications on these pins such as to SA will generally fail due to traffic congestion on the bus. SA will work fine if you use pins 1 and 2.
If using one EG4 Battery set to Address 0 (all dip switches down):
This places the BMS in host (or master) mode. The BMS polls the other batteries on pins 7 and 8. Any other communications on these pins such as to SA or the inverter will generally fail due to traffic congestion on the bus. SA and/or the inverter will work fine if you use pins 1 and 2. The inverter must support the EG4 BMS (Narada) communications protocol. SA does support this protocol, SunGoldPower does not.
The SGP 10K Inverter BMS RJ45 connector uses pins 7 & 8.
The SGP 10kw Inverter Wifi RJ45 connector uses pins 7 & 8. Pins 1 & 2 are 5vdc power for the Wifi dongle. SA can read the inverter status from this RJ45 jack. It is what I use as the USB to RS485 converter provides some isolation.
I have six batteries in a rack. Battery addresses are 1 thru 6.
I am using an EG4 communications hub between the battery stack and a SunGoldPower 10kw inverter as the inverter does not support the BMS (Narada) communications protocol.communications protocol.
Most inverters want to see 0x46 as the device code in the communication data and EG4 uses 0x4A. There are several other differences in the data as well. The hub solves these issues.
I have the Wifi RJ45 port on the inverter pins 7 and 8 (ensure pins 1 and 2 are cut/not connected as they have 5vdc and ground for the dongle power) into an USB to RS485 converter plugged into one SA usb port.
I have one RJ45 port on the bottom battery in the stack using pins 1 and 2 into an USB to RS485 converter plugged into one SA usb port.
I use two USB to RS485 converters. I have cat5 cables (pre-made commercial) in which I have cut off the RJ45 connector on one end, stripped back the insulation and connected the required two wires (orange/white and orange or brown/white and brown). I use short USB cables from the converters to SA for my use as the SA ports are to close for two converters as I use one USB port for a 10 inch touch screen display.
SA shows all six batteries and also shows all inverter stats including the SOC as reported by the hud to the inverter.
The hub also lets the inverter know what the bulk charge voltage is and this is settable on the hub as "Max Charge Voltage". The "Max Charge Current" can also be set at the hub.
Updated the EG4 LifePower4 battery firmware from 3.10 to 3.32
The baud rate on pins 7 & 8 changed to 19200 while the baud rate on pins 1 & 2 remained at 9600
I updated the EG4 Communications Hub from 1.8 to 1.10. Since the hub talks to the BMS on pins 7 & 8 the baud rate of the hub needs to be updated to 19200 as well. If I update the baud rate on the hub with the 1.8 firmware (I have two hubs) to 19200 it will also communicate with the batteries.
Likewise depending on which two wires you are using the BMS_Test software baud rate also needs to be adjusted accordingly.

Nice that’s a smart work around with the hub. I modded my cable like this based on a mixture of what support told me and what several users on here said to do. This is my connections between SG ASF 10k inverter to SG L16 Powerwall,
I severed blues and oranges

I also made several breakout boxes. The labels indicate which pins on the jack are connected. Master has all 8.
Inside all wires of same color are connected together, soldered and then insulated. I can use a regular cat5 cable for testing.
In additon you can "listen in" on the data/communications on the bus. I have several with different jack configurations.
All parts can be had at Lowes of Home Depot

Nice video man... The install looks clean. I'm in the process of switching from 2 SP6548 split phase to 2 of these parallel split phase for the 20kw (~100amp) service.
Incidentally I run everything right now on the two 6548s including hot water heater and dryer. I swapped the 4500w lower element to 2500w. Easier on the system and still have plenty of hot water.
I like the bit on solar assistant... Well done
