IQ7+/IQ7X/IQ7A Microinverters Installation and Operation Manual
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.
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 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.
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, and
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 an authorized
installer with permission and the following requirements of the local electrical
authorities should make adjustments.
Do not install the IQ Terminator while the power is connected.
.
When stripping the sheath from the IQ Cable, make sure 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.
Make sure protective sealing caps have been installed on all unused AC
connectors. Unused AC connectors are live when the system is energized.
Use the terminator only once. If you open the terminator following installation, the
latching mechanism is destroyed. If the latching mechanism is defective, do not use
the terminator. Do not circumvent or manipulate the latching mechanism.
When installing the IQ Cable, secure any loose cable to minimize tripping hazards.
