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!
