QUICK INSTALL GUIDE
Installing Enphase S-Series Microinverters
To install the Enphase S230 and S280 Microinverters™, read and follow all warnings and instructions in this guide and in the Enphase S230 and S280
Microinverter Installation and Operation Manual at: enphase.com/support. Safety warnings are listed on the back of this guide.
The Enphase Microinverter models listed in this guide do not require a grounding electrode conductor (GEC) between microinverters because ground fault
protection (GFP) is integrated into the microinverter. To support GFP, use only PV modules equipped with DC cables labeled PV Wire or PV Cable.
PREPARATION
A ) Download the Enphase Installer Toolkit™ mobile app and
open it to log in to your Enlighten account. With this app,
you can scan microinverter serial numbers and connect
to the Envoy-S to track system installation progress. To
download, go to enphase.com/toolkit or scan the QR code at right.
B ) Refer to the following table and check PV module electrical compatibility
calculator at: enphase.com/en-us/support/module-compatibility.
NOTE: S-Series Microinverters may only be paired with
60-cell PV modules.
C ) In addition to the Enphase Microinverters, PV modules and racking, you
will need these Enphase items:
•
Enphase Envoy-S™ communications gateway (required to monitor
solar production)
•
Enphase Engage Cable™, single-phase 240 VAC or three-phase 208
VAC, as needed
•
Tie wraps or cable clips
•
Enphase Sealing Caps (for any unused drops on the Engage Cable)
•
Enphase Terminators (one needed at the end of each AC branch
circuit)
•
Enphase Disconnect Tool (number 2 and 3 Phillips screwdrivers can
be substituted)
D ) Check that you have these other items:
•
Outdoor-rated, weather-proof AC junction box(es)
•
Gland or strain relief tting (one per AC junction box)
•
Number 2 and 3 Phillips screwdrivers
•
Torque wrench, sockets, wrenches for mounting hardware
•
Adjustable wrench or open-ended wrench (for terminators)
E ) Protect your system with lightning and/or surge suppression devices. It
is also important to have insurance that protects against lightning and
electrical surges.
F ) Plan your AC branch circuits to meet the following limits for maximum
number of microinverters per branch when protected with a 20-amp
maximum over-current protection device (OCPD).
Service type Max. S230s per
branch circuit
Max. S280s per
branch circuit
Single-phase 240 VAC 17 14
Three-phase 208 VAC 24 21
G ) Size the AC wire gauge to account for voltage rise. Select the correct
wire size based on the distance from the beginning of the microinverter
AC branch circuit to the breaker in the load center. Design for a voltage
rise total of less than 2% for the sections from the microinverter AC
branch circuit to the breaker in the load center. Refer to the Voltage Rise
Technical Brief at enphase.com/support for more information.
Best practice: Center-feed the branch circuit to minimize voltage rise in
a fully-populated branch.

INSTALLATION
1
Position the Enphase Engage Cable
A ) Check the labeling on the Engage Cable drop connectors to be sure that
the cable matches the electrical service at the site. Use 208 VAC Engage
Cable at sites with three-phase 208 VAC service, or use 240 VAC Engage
Cable at sites with 240 VAC single-phase service.
B ) Plan the cable length to allow drop connectors on the Engage Cable to
align with each PV module. Allow extra length for slack, cable turns, and
any obstructions.
D ) Cut a length of cable to meet your planned needs.
E ) Lay out the cabling along the installed racking for the AC branch circuit.
2
Install an AC Junction Box/Isolator
A ) Verify that AC voltage at the site is within range:
240 VAC Single-Phase 208 VAC Three-Phase
