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
