I also live in a condo with a low amp service breaker panel, but my solution was to build my own “Powerwall” which will serve multiple purposes.
That's a pretty interesting arrangement. Did you have to get HOA approval for any of that?
In my case, there's zero chance HOA will ever install solar. Our board president is a luddite. He couldn't care less about EVs.
The DCC box should work perfectly for me. It took a while for my city to grant a building permit because they weren't familiar with it but they eventually approved. I should have it all installed within the next couple weeks.
