IQ7/IQ7+/IQ7X/IQ7A Microinverters Installation and Operation Manual
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 Support
(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 Enphase
Compatibility Calculator to verify PV module electrical compatibility with the
microinverter. Use IQ8 Series Microinverters only with compatible PV modules as 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 that have been left disconnected
and exposed to wet conditions. This voids the Enphase warranty.
The Enphase microinverter functions only with a standard, compatible PV module with
appropriate fill-factor, voltage, and current ratings. Unsupported devices include smart
PV modules, fuel cells, wind or water turbines, DC generators, non-Enphase batteries,
etc. These devices do not behave like standard PV modules, so operation and
compliance are not guaranteed. These devices may also damage the Enphase
microinverter by exceeding its electrical rating, making the system potentially unsafe.
The Enphase microinverter has field-adjustable voltage and frequency trip points that
may need to be set, depending upon local requirements. Only a competent authorized
installer with the permission and following requirements of the local electrical
authorities should make adjustments.
Installers must check the manufacturing date of the products to ensure that the
installation date is within one year of the manufactured date of the products. Contact
your local distributor to validate the date code.
Do not install the IQ Terminator while the power is connected.
When stripping the sheath from the IQ Cable, ensure the conductors are not
damaged. If the exposed wires are damaged, the system may not function
properly.
Do not leave AC connectors on the IQ Cable uncovered for an extended period.
You must cover any unused connector with a sealing cap.
