IQ8MC, IQ8AC, IQ8HC, and IQ8X Microinverters Installation and Operation Manual
Always de-energize the AC branch circuit before servicing. Never disconnect the DC
or AC connectors under load.
Before installing or using the Enphase microinverter, read all instructions and
cautionary markings in the technical description of the Enphase equipment and the
photovoltaic (PV) equipment.
Do not connect Enphase microinverters to the grid or energize the AC circuit(s) until
you have completed all of the installation procedures and have received approval
from the electrical utility.
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/female connector.
To ensure optimal reliability and to meet warranty requirements, install the Enphase
equipment according to the instructions in this manual.
DANGER: Risk of electric shock. Always de-energize the AC branch circuit before
servicing. Never disconnect the DC or AC connectors under load. When the system
has an IQ System Controller, then the RSD must be switched to the off/open position
to de-energize the AC PV circuit.
Protection against lightning and resulting voltage surges must be in accordance with
local standards.
Perform all electrical installations in accordance with all applicable local electrical
codes, such as the Canadian Electrical Code, Part 1; ANSI requirements; and NPFA 70
(NEC).
The chassis of the Enphase microinverter is the heat sink. Under normal operating
conditions, the temperature could be 20°C above ambient temperature, but under
extreme conditions, the microinverter can reach a temperature of 90°C. To reduce the
risk of burns, use caution when working with microinverters.
The DC conductors of the PV module must be labeled "PV Wire" or "PV Cable" when
paired with the Enphase microinverter.
Only qualified personnel may connect the Enphase microinverter to the utility grid.
Do not attempt to repair the Enphase microinverter; it contains no user-serviceable
parts. If it fails, contact
(RMA) number and start the replacement process. Tampering with or opening the
Enphase microinverter will void the 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.
The maximum open circuit voltage of the PV module must not exceed the specified
maximum input DC voltage of the Enphase microinverter. Refer to the
compatibility calculator
microinverter. Use IQ8 Series Microinverters only with compatible PV modules per the
Enphase compatibility calculator. Using an electrically incompatible PV module voids
Enphase warranty.
You must match the DC operating voltage range of the PV module with the allowable
input voltage range of the Enphase microinverter.
The Enphase microinverter is not protected from damage due to moisture trapped in
cabling systems. Never mate microinverters to cables left disconnected and exposed to
wet conditions. This voids the Enphase warranty.
