Friends:
It is my opinion that electrical manufacturers have consistently lagged
behind the PV industry in providing specific specific hardware to meet 690
requirements. For example, we have an installation in progress with 3
XW6048 inverters. We need this many inverters for battery back up
Yes and No -- you can parallel all the inverters on the AC grid side, but then
only two can be set up to run critical circuits. Or you can have as many run
critical circuits, but then only two can send to grid. So the problem is the
functionality when you want dual purpose system.

By way of update: A meeting was recently held at the site in question and
the solution was agreed upon, if not the cause. Representatives were there
from BP, Unirac, the ESCO and Standard Solar. It was determined that a) the
RapidRac racking was not at fault and b) the installation was performed
Got a call to check out an existing, but distant system that a elderly couple
spent over $200K for a pv/battery/wind system and system never worked right.
Local electrician called to advise many design and wiring problems and suspects
orignial installer had no clue.

Automatic anything means the installer is always to blame. Good system
design puts some responsibility on the operator as well.
