Internet Access
An internet connection, with broadband router is required for
the Envoy Communication Gateway to connect to the
monitoring service.
Figure 14. Broadband Router
The Envoy Communication Gateway is an integral
component of the SunSource® Home Energy System. It
operates between the microinverters on the solar modules
and the Enphase Enlighten™ performance monitoring
website and analysis system. The Envoy functions as a
gateway and monitors the microinverters that are connected
to the modules. NOTE — For more detailed information refer
to Enphase manual.

The utility-interactive SunSource
®
Home Energy System is
for split-phase power (typical residential service) and will
only interconnect and supply power if the grid power meets
the following specification:
D
L1–L2 voltage measures between 211 volts and\ 264
volts.
D
Line to neutral/ground voltage measures between 106
and 132 volts.
D
Frequency measures between 59.3 Hz and 60.5 Hz
Roof Site Survey (Module Mounting, Penetration and
Fire Safety
The roof itself should be evaluated.
D
Fall protection for workers is addressed in OSHA
Directive STD 03-00-0-0.
D
All necessary re-roofing should be performed before
installing solar modules.
D
There must be enough area for the solar modules (one
module requires about 20 square feet).
D
Note the style of the roof — Composition (asphalt)
shingles, flat (cement) tile, S or barrel tile and
standing-seam.
D
Mark the location of skylights and plumbing vents. Solar
modules cannot block these openings in the roof.
D
Fire departments request that solar modules not be
placed within three feet of the roof's apex. Modules
should be set back from the eaves by a few feet and a
pathway, three feet wide, should always be left from the
eaves to ridge.
