AC500 is not showing any AC (grid) input from the FG2500iS generator

Hello my, AC500 is not showing any AC (grid) input from the FG2500iS generator. I just got this generator, really need the power, so I am a bit worried. Basically the generator turns on, my PV is still pulling in normally but my grid shows 0. Not sure if there is a setting or something that i should enable? Anyone can help?

Hi @Mangaliliu, Regarding this issue, we suggest that you lower the charging current a bit. In addition, please confirm that the UPS mode has been set correctly. We hope this is helpful.
We are looking forward to your reply.

Thank you for the reply. How do i do all that? Which settings do I need to enter? and I never touched the UPS mode so it is as per factory setting. Should I do something on that as well? Sorry but I am a beginner … really need some step by step guidance. Thank you so much
