IQ8MC, IQ8AC, and IQ8HC Installation and Operation Manual
Do not exceed the maximum number of microinverters in an AC branch circuit
as listed in the manual. You must protect each microinverter AC branch circuit
with a breaker or fuse of 20 A or 25 A for single-phase and three-phase
systems. Note that single-phase IQ Relays are rated for 20 A, whereas three-
phase IQ Relays are rated for 25 A.
Do not use Enphase equipment in a manner not specified by the manufacturer.
Doing so may cause death or injury to persons or damage to equipment.
Be aware that installation of this equipment includes the risk of electric shock.
The DC conductors of this photovoltaic system are ungrounded and may be
energized.
For shutting down the system, always de-energize the AC branch circuit
breaker. Never disconnect the DC or AC connectors under load.
Before installing or using Enphase microinverters, read all instructions and
cautionary markings in the technical descriptions of the Enphase equipment
and the photovoltaic (PV) equipment.
Do not connect Enphase microinverters to the grid or energize AC circuit(s)
until you have completed all the installation procedures and have received
approval from the electrical network operator.
When the PV array is exposed to light, DC voltage is supplied to the power
conversion equipment (PCE).
Risk of equipment damage. Enphase male and female connectors must only be
mated with the identical type and brand of male and female connectors.
To ensure optimal reliability and to meet warranty requirements, install the
Enphase equipment according to the instructions in this manual.
The AC and DC connectors on the cabling are rated as a disconnect only
when used with an Enphase microinverter.
Protection against lightning and resulting voltage surges must be in
accordance with local electrical codes and standards.
Perform all electrical installations in accordance with all applicable local
electrical codes and standards.
The chassis of an Enphase microinverter is the heat sink. Under normal
operating conditions, the temperature could be 20°C above ambient
temperature, but under extreme conditions, microinverters can reach a
temperature of 90°C. To reduce the risk of burns, use caution when working
with microinverters.
The DC conductors of PV modules must be labelled "PV Wire" or "PV Cable"
when paired with Enphase microinverters.
Only competent personnel may connect Enphase microinverters to the
electricity grid.
Do not attempt to repair Enphase microinverters; they contain no user-
serviceable parts and do not require any regular maintenance. If one fails,
contact Enphase Support
number and start the replacement process. Tampering with or opening an
Enphase microinverter will void its warranty.
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 IQ Cable, PV module, or microinverter) to rain or
condensation before the connectors are mated.
