Thanks Larry for all the good info, I have not had any problem with SSMPPT but
my volume is 2, a few years back I had trouble with a Morningstar product, and
they were very fast and complete in the replace ment service. Also if they
know
of a problem they are very through ingetting to the source and will make
product
changes (as they did for the priduct that I used) to prevent it in the future.
You by getting this back to them have probibly caused an evaluation and maybe a
change in design. I have been most happy with them. I use their sunlight and
similar small controllers.

Charge/Load controller)
Jason,
Not much to elaborate on. A single 200 watt Sanyo module, about 25' of 8 gauge
wire, lowest temperature 20 degrees. When the SunSaver controllers fail, they
cause a short circuit at the battery terminals. Morningstar handled the
warranty
as they do all SunSaver warranty's, quickly sending replacements with return
postage for the defective unit. We have had 4 SunSaver failures since November
1.
I sell 150+ charge controllers at our retail store each season (Nov. ~ Dec.),
most of which are MPPT. Reliability is critical to me and I pay very close
attention to failures. Most of my customers are mobile and not able to return
to
our store if a product fails. I have tested and sold many MPPT models. The
Phocos MPPT controller I was evaluating failed and we have had our share of
Outback and BZ controller failures. Blue Sky Energy has had a few bad
controllers but compared to the volume of BSE products we sell (over 1100) they
have been the most reliable. I have not yet tested Steca, TriStar, or Xantrex
MPPT controllers.
