I have a holiday cottage where I'd like to add some load shedding backup power. I want to wire it directly to some circuits on the DB, and only need it to power some lights, a router and a TV for about 4 hours (maybe boil a kettle if possible).
It would be a huge bonus if the system was quiet as the DB is in one of the small bedrooms. Having fans whirring away while guests are trying to sleep isn't going to be cool 🤣
What's the most affordable, long term solution here? Any specific products come to mind?
