[RE-wrenches] 1000V System Wiring Details

[August Goers]

Hi Dave,

We've run all the way home with 1000 V PV wire and only made splices with
Amphenol MC4-type 1000 V connectors. Going forward, we are going to strive
to put inverters on the roof to minimize the expense of dealing with the
1000 V runs. Another interesting idea is to use the 1000 V inverters but
just run them below 600 V and use standard 600 V wiring products. On a
separate note, we have a lot of 208 VAC applications in the Bay Area and
all these new neat TL inverters only run at 480 V. Someone from SMA
recently pointed out that we can source 480 to 208 V transformers for a
reasonable cost - we might look into that as well.

Best,

August
