[RE-wrenches] Inverter back feed liability

[toddcory at finestplanet.com]

worst case scenario, a battery based inverter system trying to power the grid would immediately shutdown on overload as the "infinite load" of the grid would look like a dead short.
 
also, all utility workers treat lines as "live" and routinely short out feeders before working on them... so the likelihood of this being an issue is extremely tiny.
 
someone else would have to address the liability issue, but i imagine this is covered in the utility's net metering contract.

Hello Wrenches,
I have an electrical engineer customer that asked me a "what if" that I had not heard before. If an inverter somehow back feeds the grid during an outage and damages something or hurts someone who is liable?
