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)

Finally got the generator to work properly.
Hopefully this will help some else. 
Here is what I had to do
1. Connect the generator to the AUX port
2. Connect the AUX port earth to the earth on the GRID port. I do not have the generator connected to a earth spike. 
3. Connect earth and neutral together on the generator 
4. On AUX menu, tick Gen Input and tick Gen peak shaving and set the shaving value to 80% of your generator capacity. Then set Gen Load OFF to 95% and Gen Load ON to 80% (choose your own values that work for you) 
5. On System menu, work mode 2, tick Zero Export, AND Limit to load. My generator would disconnect if Limit to load was not ticked. 
6. On System menu, work mode 1, make sure the SOC for the time slot you are running your generator in, is set to 100% and tick GEN box to charge from generator. 
7. On Battery menu, make sure the Charge Amps on Batt Type is the same as the Amps in the first block on the second screen Batt Charge. Also important is to make sure the charge amps is not set too high. Consider the power drawn from the generator to charge the batteries PLUS the power required to run the load and inverter. 
8. Tick Gen Charge, Gen Signal and Signal Island mode on Battery menu under Batt charge. 
 
What a mission to figure all this out.
