I have monitoring on all the phases on my house (in Sweden) and I can charge two electric cars, run the heating in winter, run the washer and drier and cook with two ovens a microwave and the induction hob at the same time and everything just works.
Things on three phase in my home: swimming pool, sauna, induction hob, electric car chargers, heating system and I have sockets to plug-in welding and other power hungry equipment. The rest is split on the phases. I can’t remember whether my solar system supplies on three phases or not but I think it does.
Yeah, but how many amps? What really matters is what your total available wattage is. In the US, 240v@200A (48KVA) is not uncommon. My 1979 house and every other one on the block has that, and that was assuming fossile fuel heat.
That can easily support all the things you listed and do it for a 2500 sq ft house, based on the overly conservative and outdated US NEC lead calculations.
You have it so they use it, but single phase will run it all just fine. The pool pump and welder can benefit from 3 phase, but for the pool pump the benefit is marginal. For the welder a modern inverter welder is better yet.
The pool pump on 3 phases seems slightly more efficient when I compared them last time. The pool is also being fitted with a heat pump inverter, which doesn’t need 3 phase.
