I have a Sapphire Solar Gem inverter for my Solar, in the instruction manual it shows a Smart home (future connection). I have contacted both my installer and Sapphire Solar head office in Melbourne to find out what this does. Neither of them could tell me any information about it. Head office said they have contacted the manufacturer in China as they have never had a request about it.
Interested if anyone has connected to this or has any ideas on what it might output and how to test.
