im curious david, how you measure the output of the radian since the system is
grid tie/w battery backup. the only way i have seen to do this is with a kv2c
meter on each 120 volt leg. is that how you are monitoring the output of the
inverter?
thanks,

I am using an Elkor meter with RS485 output connected to a SolarLog1000. There
are two current transformers connected to the Elkor meter. I ran each wire from
the 240 vac from the main load center through a current transformer to the
Radian ac input. Then I ran the Ac output line from t
David,
What did you choose for revenue-grade monitoring?
Comments?

I have a grid tie system with a Outback Radian and Xantrex 600 volt charge
controller with 4kw of modules and it sells back flawlessly. I have
revenue-grade monitoring on the system and I am very happy with the output.

So if I understand you, your problem is that you have a grid tied battery
backed system XW based system that ought to be exporting power. I have
installed the same system near my office. You are finding that the
customer's electricity cost has not decreased as expected.
I know that when I stand in

I would willingly clarify but I am confused about what you are confused
about. I think we are saying the same thing about off-grid systems: If
you don't consume power, battery voltage stays high and charge controllers
reduce energy harvest.

William,
I must confess to being totally confused by your post.
I am currently at my office writing to you using electricity from our
off-grid solar system. We only have the solar power, no grid power.
We get exactly as much power as I predicted we would, in fact a little
more. But, there is an i
Friends:
There has been recent discussion on this forum about PV production in
grid-tied with battery systems. I have been faced with this same problem
in a 3 XW system installed in 2009.
The customer's power bill never went down. PV harvest was abysmal. The
system would create great shor
