Well... A personal take as someone who build his own domestic p.v. power plant with storage: - 99% of what's available on the market is NOT meant to be integrated, and that's a big break. I have and EV with a 400V battery and there are on sale p.v. inverters supporting 400V batteries with BMS canbus comms. There is NO DAMN REASON why my car can't be a powerful and big extra battery for my home, just no one have done so, because grid operators dislike semi autonomous people... - despite having many open stuff Tesla is a self-contained ecosystem, which is in general a bad thing and in particular if they do not offer nothing really complete in their own garden. I do want V2L and V2H for my EV, at least many EVs offer the former. Not Tesla. - heat pumps and cold/hot water storage could enable a big energy savings well integrated with p.v. so far only Toyota have announced an experiment of car+home p.v.+heat pump project and I still see nothing on sale. Tesla offer none as well, even if "they evolve the concept of heat-pump in cars"... So well... Why buy a PowerWall? A Victron MultiPlus/Quattro and Chinese batteries offer more power, more storage, more modularity at a cheaper price... Victron also offer an EV domestic charging station BADLY integrated with home p.v. (sometimes does not star charging even if there is plenty of p.v. available, charging settings are awfully limited, for instance you can't say "go full power with Sun, but keep going from the grid as needed at maximum X amps till a certain time" and similar not that strange nor complex logic)...
