if the gen is about
3.5 kW you couls use a 500 watt Buck boost.

Greetings, Mechanics~ Please review my problem du semaine and chime in if
you are so inspired.
My prior experience with the DR series Trace inverters could be summed up in
two words: practically bombproof!

Mick,
You have missed one fundamental point: The DR (and earlier Trace
mod-square series) gulp only the peak of the AC supply waveform when
charging. They need 164V AC at the peak of the waveform at rated
charging load to supply full rated DC current. A small dip in AC

I knew Allan S. Brian T. would be among the first to chime in with helpful
observations. My recollection, however, was that prior efforts with portable
generators had worked OK with DR sets...and I know of one setup like that
which is working OK in my home county for sure. (That's a portable with
Although operating on a different voltage (230V) in this country, I noticed a
huge variation in charge rates using DR's with generator voltages on systems
that had been in a while. The generators would gradually drop their output
voltage over time as air filters clogged etc. Once they got

HI All,
If the voltage from the generators is low ( probably) then a old trick is to
use a buck/boost transformer to bump it up the voltage.
This trick has the advantage that it doesn't have the hz be too high.
