Still have those bits somewhere . When Oztules started to make his own PCB and everybody, including myself, had to try that too I diverted early from his idea of having a humongous size 2oz power board and a separate control board. Nowadays known as the madboards. It it much easier to make the power board as two separate half bridges which I have improved ever since. Mk 4 design or so I think its by now. So much so that I get away with 1oz boards, even for the 6KW inverter. So, yes, that idling power is with a single transformer inverter though I don't call it "ozinverter" as it only resembles his pioneering work in principle but no more. When my warpverter was working I recall the combined idling power was <30W for the 4 transformers & electronics. I'll update that when the new version is up and running. Thanks for that background information, it helps in understanding your journey. I only found this forum and all you guys because I wanted to understand why a normal grid tie inverter couldn't be made to run as a stand alone device. It really got my attention when I read how many of you were building your own inverters and I started to get enthusiastic. I wasn't all that keen on building a Warpinverter to start with because of it needing four transformers and not just one  ...  but as I got to understand it a little better I figured why not give it a go  ...  especially with all the expertise and information available here. If mine has a combined idling power of <30W I'll be very happy too.
