SW4024 question [RE-wrenches]

[Richard Perez, Home Power magazine]

<x-flowed>Hello Wilson

You are not alone. Others are having exactly the same problem with 
the SW series in sell mode. It seems that the software is not up to 
the job of balancing both utility-intertie and battery maintenance. 
Currently, as far as I know, there is no real fix for this. With the 
current software, you must manually choose between SELL and LBX modes.

Joe Schwartz and Michael Welch of Home Power are working on an 
article about this. They are in contact with Trace (Christopher 
Freitas) and various Wrenches concerning this.

I'm also sending this message to the RE Wrench mail group. Perhaps 
there is someone who has solved this problem.

Wrenches, please respond to both the Wrench Group and to Wilson 
<DosBobos at aol.com> on this message.

>Hi there,
