[RE-wrenches] System Performance | Battery Based Grid Tie

[Darryl Thayer]

I hope I did not give the wrong impression, my large system I gave the sunlight to AC not the inverter efficiency, I have access in the data to the module output to AC and it is very good, I do not remember the numbers, but close to 90%  the low performance of my system is the measured underperformance of the modules with some module failures.  I can not say why some modules have failed, but the outback equipemnt has not.  I have 12 inverters GVFX 3648  on one system, and very little maintence.  The syetem will run without batteries.  I was checking battery condition and shut off the batteries and it ran for a month. before I checked and turned the batteries back on.

We have found that most of our batt systems are running at around 85% sell back.

that's a nice conservative estimate for input STC kWh to sold kWh jeremy 
  
as far as charge controller kWh to sold kWh, my OB 3648 runs in the ~87% range

Wrenches, 
I am looking for advice and or comments on system  performance from a Grid Tied battery back up system. 
Is 65% efficiency fair as far as what goes back to  the grid? 
Is PV watts a good tool for that.  
Commnets are welcome!
