@arch@floofy.tech you can kinda craft a 'plug in system' by hooking up some panels to a (e.g second hand) grid-tie inverter, and just plug that into a random power outlet. up to 1200w is pretty safe for such setups, although it may upset some electricians if they see it (just remind them this is how plug in systems also work though :P) there are also fairly cheap batteries (e.g a Marstek Venus A is ~500 euros and has 4kwh), and syncs with your powermeter.
