Searching for a brain storming session.... Let's say I have a dozen tiny houses on my property. Each house has it's own inverter, batteries and solar. But we want to link the houses together. Recently I posted that I was planning to link my daughter's tinyhouse to ours via a 600v/240v transformer. So let's say I've created a utility line that circles the property using 600v (or 7500v... doesn't matter). If I connect one inverter as master and use it's frequency controlled output as the "pilot signal" for the community, then other inverters can connect as they desire to the "grid". The problem arises when 100% of my dozen tiny houses are connected and I can't frequency shift fast enough and end up with 12x6kw of solar inverters back feeding my "master" unit.
Also, the tiny house inverters would see the community grid varying in frequency and probably drop their connection or never connect at all. So if I simply installed a relay on the output of each tiny house inverter to connect to that community grid, there's the question of making sure we are in phase before allowing the connection, and these inverters wouldn't follow the phase anyway since each would think it was the "master".....
Ideally, I'd love to have a tiny grid that the various tiny houses could latch on and give/take power as needed. But the devil is in the details. Any ideas?
