Hello, I reside on the 4th floor of an apartment in Spain, but the council/community company, have refused me the installation of a private power extension lead, to charge up my Volt, so I've been looking for other alternatives, and after watching a youtube video about DIY EV Range Extender, I have preliminary setup a similar system, but I can't get the lights to even go green on the Volts' portable J1772 charger. I have a brand new 3kW Pure Sine Wave Inverter (YueQuing Reliable Electric), which produces 240 volts AC @ 50Hz. The standard charger that came with my 2012 Volt, works when plugged into the mains socket, but doesn't when plugged into the grounded inverter. Can anyone help me with this problem please? I'd also like to say that the Chevrolet Volt, is the most brilliant versatile Electric/Generator car, I've ever had the pleasure of owning.
