Does the two-way meter have a way to prevent back feeding the grid in the event of a power outage? Having an unregulated device even under 800W seems like it could be dangerous to anybody working on the power lines.



> prevent back feeding the grid in the event of a power outage?

Yes - such devices need a constant grid output to sync to. When the grid drops, their output drops. Furthermore, at 800W, it wouldn't be able to put any voltage onto the grid even if it tried to as it would get overloaded (it'll be trying to power up the entire neighborhood).


I think the idea was maintenance, so the connection to the neighbors would've been interrupted, thus the only connection would be through the person doing the maintenance.


The inverter does that, as it shuts off the moment voltage is not in the +/- 10% range of the nominal 230V.
