I thought I remember hearing/reading that the AIRX disconnected the generator from the battery bank (very quickly) in order to read the battery voltage so that...

No, I think the AIRX has some additional circuitry in it to "load" the alternator electrically, essentially acting as a brake. In my opinion, the AIR303 series...
I wasn't trying to explain it, only noting that it could be done. I definitely discourage you from trying to build such a device, and did not assume that you...

Actually I have an AIRX flying that seems to stop every now than then for no good reason - even when I think the wind speed isn't too high. Maybe its doing...

Martin: The idea of using a Synchronized MSW Vac for a grid tied system is quite problematic for the converter or the GRID power. The problems are so many...

Derek, I've not seen a schematic of the circuit, and the boards in both of my AIR303s were potted. But when I connected an analog current meter between the...
Hi Marty, Yes - I've seen the MOSFETs in it that seem to stop the turbine when it wants too (like when the wind is too fast and its just edging on going mad...

Are you talking about inverting AC to run DC appliances? Why go thru all of that? Just buy a 12v electronic ballasted flourescent light and run it directly off...
I think that compact fluorescents operate like LCD panel flourescents - there is an "inverter" board that makes high frequency high voltage output (and you can...

Hi Marty, That is interesting - I didn't realise that there was any amount of cleavernees to the AIR before the AIRX. I also think I remember that the AIR403...
