utility obfuscation and obstruction [RE-wrenches]

Kurt,

Thanks for your suggestion. Several New York utilities are not allowing any
connection to an SW inverter whatsoever - not even to ACIN2, so LBX is not
an option.

I got the impression that even Trace didn't think the LBX mode worked
effectively given the complexities of some parameters being temperature
compensated and some not. I always liked the concept but thought they
actually discouraged its use, so I am interested to hear that you have
employed it effectively.

I hope you have them in LBX.  I have one customer who after operating
his system in LBX, decided they like it better than being grid-tied.
Perhaps not as efficient (although with no silent sell?), but at least
you're using the bulk of the energy.  You can also stage a load or two
on and off the solar/grid (using the SW aux relays and contactors) to
try and make the system more efficient.
