I don't really have many of those whenever power usages though. I don't need to charge a car, don't have a dishwasher, washing machine runs on low heat so doesn't really use that much power. My heating/hot water is done by a heat pump which would require a house battery as I can't just plug it into something myself.

Pretty sure a lot of my usage is from long continuous things. I could plug my home office into a portable (or barely portable with the size of some of them) battery and charge that with some solar panels in the garden. Use some extension leads to connect up at least the bedroom and living room too. The problem is that I haven't found a cost effective way to do so even though I otherwise want to.
