ST versus Sunny boy [RE-wrenches]

[Baran Galocy]

Concerning the readouts and de-rating,

I have installed a SB-2500U with a built-in display.  This display keeps
track of day-to-day cumulative generation, as well as the daily output and
real-time dc voltage tracking.  The Sunny Boy has software that de-rates the
output when temperatures get too high.  This allows the unit to run cooler,
and get back to its maximum efficiency in a short period of time.  The Sun
Tie shuts down power production entirely when the temperature rises.  I
can't get over 1,320 watts out of a ST-2000 before thermal cycling heads its
ugly rear, even though I have 1,750 - 1,900 watts trying to be efficiently
inverted.  To Trace's credit, they are shipping 2 more SunTies and two
shipping labels to return the old ones.   I look forward to the days when
this equipment has become ubiquitous from the research and development view.
What good is cutting edge when all it does is bite you?
