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?   Quote   Funnily enough, the original idling power with the EG8010/ IR2110/ totem pole arrangement as per madness design, but with identical transformer as above, took 29W all up to run. So, something to consider down the track if you are concerned about idle power. That's almost half, amazing. So you're putting that down to Poida's nano and opto isolated totem pole drivers as per wiseguy's design? I am too far off finishing yet to be too concerned about idling current  ...  I just hope I can get it to run, let alone idle.   I don't really understand the principle, but I appreciate Tony's guidance in planning the toroid build to operate at a much lower flux density than general commercial ones. I'm assuming that's where the first big level of idling power is reduced.
