I totally agree with you, about the safety aspect, from my comment I did not really expect to be taken serious
Just noticed they statring to be sold on ebay single inverter going for $200 posted in OZ.
If the inveter of that size could be approved to be plug into the power point, a plug and play DIY installation with your own PV mounted, PV voltage string kept below ELV limits .
Just think of a 200watt Grid Tie PV sysyem for under $1000.
Imangine the take up if everone could do that, all the phantom power comsumption at home be offset with PV energy.
Phantom power of all electrical devices is typical around 1kwh in a OZ home acording to some reports.
