Serial number empty

[deosrc]

I usually run in mqtt mode and noticed that the mqtt topic wasn't being set correctly. It seems that the inverter serial number is not being received correctly resulting in an empty segment in the mqtt topic of solar//status (using a topic prefix of solar).

When I run in monitor mode, this is the output:

Turned out to be a problem with the inverter. When I checked the inverter it had lost it's serial number, mac address, all history and even the time. There wasn't anything in the events list.

Isolating it from both the mains and solar panels, waiting for it to fully power down, and then reconnecting it seems to have sorted it.

Great that you solved it. Currently it always puts the serial number in the topic. This is done in order to support multiple inverters. But it would be a good change to omit the serial number when there is only one inverter. Then the full MQTT topic would also be configurable.

Could be a possible future enhancement.
