Outboard equipment for PV5 [RE-wrenches]

[Bill Brooks]

Roger,

The philosophy holds true for lots of equipment. At lower voltages, the
mistakes are more forgiving in general. Lack of training is a problem for
all PV system types, and those engaged in selling high voltage equipment
have an obligation to focus on training. Also PV modules and inverters do
not a system make. I know John Berdner (SMA) and Kent Sheldon (Trace Tech)
are very well aware of this. Since John will be marketing to dealers all
over the place, he has said in previous postings that training will be
available.

It's not that it is rocket science--just that without attention to some very
important details, trouble arrives much more quickly.

Bill.
