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. </DIV>

<DIV>Jason,</DIV>
<DIV>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.</DIV>
<DIV><BR></DIV>
<DIV>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.</DIV>
