PowMR 3000 24V Syatem

I have the same unit you tested on your video and wanted to know when using PV power with battery backup, my system for some reason ( probably settings ) drops power for about 1 second before grid power takes over.

so you know what setting this is on the PowMR that needs changing to ensure seamless transition from PV / inverter power to AC when voltage drops below predetermined set point?
