How good is the power quality, if you’re making best-effort power from solar panels with neither a grid tie nor any associated batteries? If it looks like it’s working but provides brownout power frequently, I imagine it could damage downstream electronics enough to not be worth it.
At least as implemented by SMA, it doesn’t brown out. You either get the full voltage or overcurrent protection trips and it needs to cycle. If you draw much less than the solar array is currently able to power you get steady current.
the amount of batteries needed to prevent this would would be quite small compared to the amount of batteries needed to power the house for any meaningful duration.
I agree that something integrating even a very small battery would be great, and I don’t know why no one offers this.
