  • Yep. I held my father’s hand when he died. When it was over I hugged him and told him we’d be okay on our own now and that we’d manage.

    I was mostly right. Mostly. The waves came and went and I thought I’d be over the worst - but now, a year later I sometimes miss the guy with a pain that feels like it will never end in that moment.

    I planted a tree and put a bench under it at the end of a small valley where I now own some meadows and where we used to go together and chop firewood. When it gets too bad I take my dog up there and sit down and tell my dad what’s going on.














  • An engineer dabbling in such things explained to me, that it is hard enough to regulate a small island network frequency and voltage-wise from a single point. Reacting to whatever another source (something like another solar inverter out in the garden with a few panels of its own, e.g.) in the same island grid does could easily lead to potentially destructive oscillations in the regulation circuit. Large grids have “mass” - literally, because large generators and electric motors are spinning at whatever speed they are spinning in whatever phase they are in. So small disturbances from regulating too quickly or a little wrong just disappear into that. The same doesn’t go for a small island grid, so at Fronius they have decided to put 52Hz on the grid which by standard prevents other sources from syncing. Electric utilities do the same when they have to power small villages from diesel generators temporarily - 52Hz and the house mounted solar generators don’t sync.
