[RE-wrenches] DC Power Supply for powering up SMA (or similar) inverters?

[Ross Taylor]

Hi all,

Can anyone recommend a DC power supply they've used for powering up
inverters, for programming purposes?  I had a custom-made one, but it
finally bit the dust.  It was also bulky.  Size/portability is a factor.
 SMA's usually stellar tech support folks were (I guess, understandably)
reluctant to offer any guidance. 120VAC with an output in the 200-400VDC
range.  I don't have battery banks at these sites, so the only programming
options are to wait for wind (be nice!!!) or power them up this way.

I know there are a ton on-line, but I'm specifically hoping for some
personal experience and recommendation.

Thanks much!

Ross
