Without knowing which devices you want to power with the UPS, it's difficult to give a precise recommendation.
Since you only want to power the GW3000 and then backfill, it seems realistic that many UPS models on the market would be sufficient—even for nearly two days—provided the battery is in good condition. A more common approach is to use the UPS to support multiple devices, such as a network switch, NAS, computers running WeeWX, routers, or access points. Many UPS units and NAS devices support automatic shutdown when power is lost, right out of the box. Here’s my setup: I use an EATON Ellipse PRO 1200 to power a NAS, one access point, a network switch, some Ecowitt gateways, a router, and an n100 mini PC. The NAS is configured to shut down automatically after 10 minutes without power. I’m not sure how long the UPS could sustain all these devices, but our power grid is very stable. I can only recall outages lasting less than an hour, and they happen less than once a year. I plan to install an automatic blackout switch. I have a 24 kWp PV system with a 22 kWh battery, so the UPS would only need to bridge the brief moment the blackout switch takes to activate. Auchtermuchty Weather schrieb am Donnerstag, 2.
