Battery Capacity calculated wrong for 9.5 battery

[gcoan]

I have a 5.2 and a 9.5 battery on separate inverters.

Noticed today that the 9.5 battery (recenty replaced) is showing as 6.4 capacity, but all the HA metrics I look at give the correct capacity, as does the BBC basic app and the GivEnergy app.

I did have custom_dod set to 80 for this battery but use_custom_dod set to false, but even changing it to custom_dod 100, and turning use_custom_dod on or off, still shows the wrong capacity

Checklist:

• [X ] I updated to the latest version available

Release with the issue: 0.2.4

Last working release (if known): Tried it with 0.2.2 and 0.2.0 and both the same issue

Browser and Operating System: HA companion app, ipad Same with iPad Safari

Description of problem: Should show 9.5 capacity. Suspect somehow it is not reading correctly the capacity

[gcoan]

Found the cause of the issue, for reasons I don't understand GivTCP was reporting the 9.5kW battery capacity as 6.4kWh.

This was only reported in MQTT, not in a HA entity, so wasn't immediately obvious

I could see soc_max changing from 9.52kW to 6.4kW in the predbat log at the run at 12:10. In the inverter notifications this corresponded to a 'low voltage' error so maybe that caused the glitch.

Restarting GivTCP and it now shows correctly as 9.5kW in MQTT and the battery card
