IQ7+/IQ7X/IQ7A Microinverters Installation and Operation Manual
Ensure that all AC and DC wiring is correct and that none of the AC or DC wires
are pinched, shorted, or damaged. Ensure that all AC junction boxes are properly
closed.
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.
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. While connectors are
rated for disconnecting under load, Enphase does not recommend disconnecting
the DC 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 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 matching male/female connector.
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 standards.
Perform all electrical installations in accordance with all applicable local electrical
codes.
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 the risk
of burns, use caution when working with microinverters.
The DC conductors of the PV module must be labelled "PV Wire" or "PV Cable"
when paired with the Enphase microinverter.
Only qualified personnel may connect the Enphase microinverter to the utility grid.
