The real solution is the dynamization of electricity prices. This needs some adjusting from your average consumer but not a lot if done right. In Germany there are startups like 1.5C, Enpal etc which will sell you a heat pump, solar, ev charger pack with some "smarts", switch you over to a dynamic pricing electricity contract and then claim to optimize the overall cost (i have no direct experience of my own). If you are willing to take a small amount of temperature swing your house is a big thermal battery (even more so if you have a heat pump to water with a big, well insulated reservoir), your ev is a battery with vehicle to grid. With this you can shift your main loads a good amount. Washing machines and dryer as well as cooking/baking might be slightly more problematic/harder to shift, though the car battery should be more than enough for average evening cooking and i have seen washing machines/dryers which can take an external signal as to run when the price is low/there is excess electricity...
