I doubt anyone here has bought one yet, or they would probably have posted an article about it.

I do want to make one point clear: it is possible to build what is advertised there, for that price.

Safety is fine to worry about Bruce, but needs to be for the right reasons.

These little units will fail fairly early on due to cap failure. They are subjected to unrealistic ripple, with the barest amount of capacity and bulk... consequently, the firs...

If you must use small inverters go with something approved like the Enphase micro inverters.

Never heard or seen anything about them since.

In the US, UL cannot issue an approval of any plug-in grid-tie inverter. The National Electrical Code forbids that arrangement and UL is the lab that the insurers use, so they will not knowingly issue a UL cert to any device that violates the NEC.
