I've been looking at these new GTIs on Ebay..

1200w+LCD grid tie solar power inverter 28-52vDC/110vAC - eBay (item 250645344281 end time Jul-05-10 01:26:38 PDT)

120vac or 220vac? I'm wondering if there is any difference in how they work.

In the case of a home with two 120vac loops off their 220vac breaker panel,
if a GTI was connected to a 120vac loop that was lightly loaded,
would loads on the other loop be supplied by the GTI?

Is there any advantage to using a 220vac GTI? vs. a 120vac GTI?

Is there any difference in what wattage a net-meter would see,
if it was a 120vac GTI and the load was not balanced? (Light on the GTI side)?
