QUICK INSTALL GUIDE
Replacing Enphase S230 and S270 Microinverters
Read and follow all warnings and instructions in this guide. Safety warnings are listed on the back of this guide. Use this procedure to replace a failed
S230 Microinverter or S270 Microinverter using the parts provided in the replacement kit. Read and understand the safety information at the back of
this guide before installing the replacement microinverters.
The microinverter has a Class II double-insulated rating, which includes ground fault protection (GFP). To support GFP, use only PV modules equipped
with DC cables labeled “PV wire” or “PV cable”. Refer to local electrical codes and standards for PV array and racking grounding requirements.
E ) Check that your AC branch circuits meet the following limits for
maximum number of microinverters per branch when protected with
a 20 A over current protection device (OCPD).

and cautionary markings in the technical
description, on the Enphase Microinverter
System, and on the photovoltaic (PV)
equipment.
*WARNING: Do not connect Enphase
Microinverters to the grid or energise the
AC circuit(s) until you have completed all
of the installation procedures and have
received prior approval from the electrical
utility company.
Microinverter Safety
+DANGER: Risk of electric shock. Risk of
re. Do not attempt to repair the Enphase
Microinverter; it contains no user-ser-
viceable parts. If it fails, contact Enphase
customer service to obtain an RMA (return
merchandise authorization) number and
start the replacement process. Tampering
with or opening the Enphase Microinverter
will void the warranty.
+DANGER: Risk of re. The DC conductors of
the PV module must be labeled “PV Wire”
or “PV Cable” when paired with the Enphase
Microinverter.
*WARNING: You must match the DC
operating voltage range of the PV module
with the allowable input voltage range of
the Enphase Microinverter.
*WARNING: The maximum open circuit
voltage of the PV module must not exceed
the specied maximum input DC voltage of
the Enphase Microinverter.
*WARNING: Risk of equipment damage.
Install the microinverter under the PV
module to avoid direct exposure to rain, UV,
and other harmful weather events. Always
install the microinverter bracket side up. Do
not mount the microinverter upside down.
Do not expose the AC or DC connectors (on
the Enphase Cable connection, PV module,
or the microinverter) to rain or condensa-
tion before mating the connectors.
*WARNING: Risk of equipment damage. The
Enphase Microinverter is not protected from
damage due to moisture trapped in cabling
systems. Never mate microinverters to
cables that have been left disconnected and
exposed to wet conditions. This voids the
Enphase warranty.
*WARNING: Risk of equipment damage.
The Enphase Microinverter functions only
with a standard, compatible PV module
with appropriate ll-factor, voltage, and
current ratings. Unsupported devices include
smart PV modules, fuel cells, wind or water
turbines, DC generators, and non-Enphase
batteries, etc. These devices do not behave
like standard PV modules, so operation and
compliance is not guaranteed. These devices
may also damage the Enphase Microinverter
by exceeding its electrical rating, making the
system potentially unsafe.
;WARNING: Risk of skin burn. The chassis
of the Enphase Microinverter is the heat
sink. Under normal operating conditions,
the temperature could be 20°C above
ambient, but under extreme conditions the
microinverter can reach a temperature of
90°C. To reduce risk of burns, use caution
when working with microinverters.
✓NOTE: Many Enphase Microinverter models
have eld-adjustable voltage and frequency
trip points that may need to be set, depending
upon local requirements. Only an authorised
installer with the permission and following
requirements of the local electrical authorities
should make adjustments.
Enphase Cable Safety
+DANGER: Risk of electric shock. Do not
install the Enphase Cable terminator while
power is connected.
+DANGER: Risk of electric shock. Risk of
re. When stripping the sheath from the
Enphase Cable, make sure the conductors
are not damaged. If the exposed wires are
damaged, the system may not function
properly.
+DANGER: Risk of electric shock. Risk of re.
Do not leave AC connectors on the Enphase
Cable uncovered for an extended period. You
must cover any unused connector with a
sealing cap.
+DANGER: Risk of electric shock. Risk of re.
Make sure protective sealing caps have
been installed on all unused AC connectors.
Unused AC connectors are live when the
system is energised.
*WARNING: Use the terminator only once. If
you open the terminator following installation,
the latching mechanism is destroyed. Do
not reuse the terminator. If the latching
mechanism is defective, do not use the
terminator. Do not circumvent or manipulate
the latching mechanism.
*WARNING: When installing the Enphase
Cable, secure any loose cable to minimise
tripping hazard
✓NOTE: When looping the Enphase Cable,
do not form loops smaller than 12 cm in
diameter.
