The total idle power, including core magnetising current and all the electronics, is 17W at 55V battery voltage. Wow, certainly very impressive and glad to hear you've made such progress. Just so I'm clear here  ...  this is with an Ozinverter? I should tell you here that I followed the "ozinverter" story for about 12 years by now, the first version was what everybody did back then, buying the power & control PCB from Powerjack and do the rest at home to make an inverter. 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.
