XR2500 [RE-wrenches]

[Matt Lafferty]

Wrenches:

The XR also has included some improved "Installer Friendliness".

1.  The Combiner is reconfigured and relocated to provide easier wiring and
more room.

2.  The KO's at the bottom provide for larger conduit entry.  (Last I heard,
up to 1" for DC entry)

In addition, I'm told, they have re-worked the cooling system substantially
for more reliable operation at elevated ambient conditions.

Hope this is all true and helpful!
