I have had failures with the Sunsaver MPPT. I have used them with a single 
Sanyo module in small battery systems. Perhaps they just can't handle the 50.9 
Voc.

Try SunSaver MPPT. 

15 amps, MPPT and load control (or light) control

 

Use the MSC to connect the controller to your PC and adjust many settings and 
get log data. 

 

We use a lot of them and have had very few issues. 


Thank you,

Hello Eric:
Would you please provide a reference to the literature where Enphase says, 
"using a cut extension cable will void the warranty of the entire  
installation."  I didn't see anything in the installation manual.  Also, 
Enphase 
did recommend the application to me.  It was actually pretty easy to make the 
connections without 'crossing phases.'

Re: [RE-wrenches] SunSaver failures; MPPT controller reliability (1A Charge/Load controller)

2011-01-23 Thread Darryl Thayer 
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.

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.
