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 20 A maximum
breaker or fuse as appropriate
DANGER: Risk
of electric shock.
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 risk of electric shock.
The DC conductors of this photovoltaic system are ungrounded and may be energized.
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, on the Enphase equipment and on 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
Protection against lightning and resulting voltage surge 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).
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.
The DC conductors of the PV module must be labeled “PV Wire” or “PV Cable” when paired
with the Enphase Microinverter.
DANGER: Risk of
electric shock.
Risk of fire
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 Enphase customer service to obtain a return merchandise authorization
(RMA) number and start the replacement process. Tampering with or opening the Enphase
Microinverter will void the warranty.
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 IQ
Cable, PV module, or the 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 Enphase
Compatibility Calculator at: https://enphase.com/en-us/support/module-compatibility to
verify PV module electrical compatibility with microinverter. Use IQ8 Series microinverters
only with compatible PV modules as per Enphase compatibility calculator. Using electrically
incompatible PV module voids Enphase warranty
