Would you be able to avoid leaking back into the grid?

During a recent major weather event outage, a neighbor up the street was running a generator, that I think was not properly islanded. I experienced it by having some devices making weird sounds because they were receiving some low level voltage. They were probably leaking to tens of neighbors and losing generator output in the process.

This doesn't put power back through the home. It acts more like a UPS. You plug in the stuff you need up during an outage to the back of it like a power strip.

Yikes! I’ve heard so many similar sounding examples of misuse of generators and sketchy generator setups. Pila has the grid disconnect built in so there’s no risk of un-intended backfeed when islanded

Not just that, it's a danger for the linemen trying to fix the neighbourhood.

Right! Unintentionally back-feeding is a huge safety risk, and I hope that smarter safer solutions will prevail over the all-too-common hacky unsafe approaches. But also, I get it. I’ve wired generators back into panels - safely - in situations where it’s that or no power for days, you start taking matters into your own hands
