I have now spoken to probably everybody in Sunsynk and no one can give me some sort of answer. And do not think for one moment it is easy to book a warrantee claim for something that was not finally installed and subsequently not registered for its warrantee. Unfortunately for me I am still waiting for wifi. So, they cannot look up on the logger. They do not answer phones. Do not call you back. But it seems after I took the matter up with their chief operations manager that something is happening.
