[Bug]: 'Growatt' - 'SPF5000TL' - Sporadically stops recognizing inverter

[PrimusNZ]

Describe the bug

Since the major update in roughly July/August, my inverter is sporadically unrecognized by the addon.

Sometimes it takes a couple of days and several reboots before it becomes recognized again - I haven't been able to work out a specific pattern as to why.

I know my inverter is supported as I wrote the code that added the support for it months ago.
