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 multi-phase
systems. Note that single-phase IQ Relay is rated for 20 A, whereas multi-
phase IQ Relay is rated for 25 A.
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 the 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.
WARNINGS:
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 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/female connector.
NOTES:
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 surge must be in
accordance with local electrical codes and standards.
Perform all electrical installations in accordance with all applicable local
electrical codes and standards.
Microinverter safety
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
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.
DANGER: Risk of
fire.
The DC conductors of the PV module must be labelled “PV Wire” or “PV Cable”
when paired with the Enphase microinverter.
DANGER: Risk of
electric shock.
Risk of fire.
Only competent personnel may connect the Enphase microinverter to the
electricity grid.
Do not attempt to repair the Enphase microinverter; it contains no user-
serviceable parts. If it fails, contact Enphase customer support 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 IQ Cable, PV module, or microinverter) to rain or
condensation before the connectors are mated.
