Hi,
I had similar experience - registered in March - got popup, and no more. A couple of weeks ago, I needed technical support, and in the email I queried the warranty certificate at the same time. I got an emailed warranty certificate sent to me within a day or 2.
I had emailed support@sunsynk, and the warranty query was forwarded to Dominique, who sent me the emailed certificate.
Perhaps you could email Dominique directly with your serial number and date of registration ( I sent approximate date)
