A1 — System Summary
For Construction: March 15, 2013
Project #: 412
Client: Mr. Jeff Bailey
Address: Corsicana, TX
System Size: 3.180 kW
Module: Solar World SW-265
Microinventer: Enphase
Project Report
The following design describes a Solar PV system with a peak STC DC size of 3.180 kW
and an estimated electrical generation of 4828 kWh per year.
The modules are mounted on the south facing roof with an 185º azimuth at a 32º tilt. The solar PV AC array consists of
(12) SW-265 solar modules with each solar module in the array connected to an Enphase M215 microinverter. They
have 96% CEC efficiency rating
From each module, DC power is connected directly to an Enphase microinventer mounted below each module.
240VAC power from the microinventer passes through a renewable energy credit meter; next, through a disconnect
switch and then ties into solar source breaker located in the Lennox SunSource®XC21-060 (5-Ton) air conditioner.
Utility: United Cooperative Service

ENPHASE MICROINVERTER
How the Enphase Microinverter Works
The Enphase Microinverter maximizes energy
production from the solar module array. Each Enphase
Microinverter is individually installed on one solar
module in the array.
This unique con’iguration means that an individual
Maximum Peak Power Point Tracker (MPPT) controls
each solar module. This ensures that the maximum
power available from each solar module is exported to
the utility grid regardless of the performance of the other
solar modules in the array.
Even if individual solar modules in the array are
affected by shading, soiling or orientation, the Enphase
Microinverter ensures optimum performance for each
associated solar module. The result is maximum energy
production from the SunSource
Energy System.
Enphase Microinverters for 3−Phase Applications
Each Enphase Microinverter automatically connects to
one phase of a 3−phase system. It senses the grid and
synchronizes to that phase. When applied in groups of
three it creates a balanced 3−phase system. If systems
are installed in something other than multiples of three a
small imbalance will be created across the phases. The
maximum output of each inverter is 0.92A. This would
be the maximum imbalance possible.
Enphase Microinverter Status LED Indications and
Error Reporting
Startup LED Operation:
Six short green blinks when DC power is ’irst applied
to the Enphase Microinverter indicates a successful
microinverter startup sequence.
Six short red blinks when DC power is ’irst applied to
the Enphase Microinverter indicates a failure during
microinverter startup.
Post−Startup LED Operations:
Flashing Green−Producing power and
communicating with Envoy
Flashing Orange Producing power and not
communicating with Envoy
Flashing Red Not producing power
GFDI Fault:
A solid red status LED when DC power has been
cycled, indicates the Enphase Microinverter has
detected a ground fault (GFDI) error. The LED will
remain red and the fault will continue to be reported by
the Envoy until the error has been cleared. The error
can only be cleared via the Envoy after the ground fault
condition has been remedied.
Other Faults:
All other faults are reported to the Envoy.

E3 — Module Attachment Hardware
NOTE — Check with local building department to identify any unique
wind or snow load requirements that pertain to your jurisdiction. A
combination of shortening the maximum span between roof
attachments and increasing the length of your lags will enhance the
wind load rating of PV System. When the proper number of
attachment points are included, PV System panels are rated for
coastal conditions in Florida.
Install the flashing below the upper shingle to allow water
to run around the raised penetration point. Seal the
penetration and lag screws with appropriate roofing
sealant.
