I have a switching station with primary input via solar and 240 V inverter; the secondary input uses the house mains.
In order to 'bridge' the time in switching from the primary to the secondary input I use a UPS for sensitive devices (e.g., computer, router, etc.).
The UPS constantly draws some 100 W irrespective of what devices connected to it are in use.
Could anyone please suggest an alternative to the UPS with less of a load in order to bridge the time?
Best regards
Victrons inverters do have a UPS function, it however is is not as sensitive/fast as a dedicated UPS. They also have other factors that can make it less reliable, such as setup/install.
So if the apliances really are sensitive, stick to having a certified UPS in the system. That being said all our computers and routers are running off a 3kva multiplus and they haven't shut down on grid loss. (And no UPS)
There are quite a few in the range starting as low as 800Va if you want grid in as well.

Your other option is a small phoenix with a bit of solar then they are totally off grid all the time.
