I recently purchased an APC Back-UPS Pro 2200VA and wanted to connect it to my Ecoflow Delta 2 power station to extend battery life during power outages. While the UPS charges when directly connected to the grid, it switches to battery power as soon as the Ecoflow Delta 2 is disconnected from the grid. This behavior is puzzling, especially since my older APC UPS and the Ecoflow Delta 2 Max work seamlessly in similar setups. I’ve tried adjusting sensitivity settings and checking voltage regulation, but the issue persists. Does anyone have insights or troubleshooting steps to resolve this? It would be great to find a solution to keep the UPS online while using the Ecoflow Delta 2 as a backup power source. Any advice or experiences would be greatly appreciated!
