The status image shows battery SoC @ 82%. Presimedly that value is from a Victron shunt-based battery monitor (a SmartShunt?)
The SoC is derived from parameter values prorammef into the monitor, combined with its tracking charge/discharge current. The battery must be fully charged before the monitor will sync at 100% SoC.
With the Cerbo and internet communications, the system can be connected to Victron Remote Management (VRM) for remote monitoring, and remote programming changes.
Yes Victron smart shunt and Cerbo
All done now. Yes itâs the fact that it has a very low current draw on it for say 7 days and the battery and SS donât recognise it. So we ignore the SOC and just use the voltage. Today I wired up the auto start for the generator and now my friend can start the generator with his phone and it is also programmed to start at 51.5V and stop at 54V but we will have to wait a day or two to see if it works.
Thankyou so much to everyone for help and guidance. 
How is the current threshold programmed in the Smartshunt? The default setting is 0.1A. = 5W.
If there are no problems, you can go down to 0A.
The BSL is very clearly connected by can cable to the GX device.
Why is it not being set as the battery monitor? It would know its own state of charge and health.
That being said i do know they had a firmware that could have false 100% trigger usually when a large charge current is applied then it drops off.
Yeah agreed these are often wrong.
