IQ8MC, IQ8AC, and IQ8HC Installation and Operation Manual
The maximum open circuit voltage of the PV module must not exceed the
specified maximum input DC voltage of the microinverter. Refer to the Enphase
compatibility calculator to verify PV module electrical compatibility with the
microinverter. Use IQ8 Series Microinverter only with compatible PV modules as
per the Enphase compatibility calculator. Using an electrically incompatible PV
module will void the microinverter's warranty.
You must match the DC operating voltage range of the PV module with the
allowable input voltage range of the microinverter.
The 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 microinverters'
warranty.
The 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, and so on. These devices do not behave like standard
PV modules, so operation and compliance are not guaranteed. These devices
may also damage the microinverter by exceeding its electrical rating, making
the system potentially unsafe.
The microinverter has field-adjustable voltage and frequency trip points that
may need to be set depending on local requirements. Only a competent
authorized installer with permission from local electrical authorities should
make adjustments.
Installers must check the manufacturing date of the IQ8 Series Microinverter 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 an IQ Cable, make sure the conductors are
not damaged. If the exposed conductors are damaged, the system may not
function properly.
Do not leave AC connectors on an IQ Cable uncovered for an extended
period. You must cover any unused connector with an IQ Sealing Cap.
Make sure protective IQ Sealing Caps have been installed on all unused AC
connectors. Unused AC connectors are live when the system is energized.
Use an IQ Terminator only once. If you open an IQ Terminator following
installation, the latching mechanism will be destroyed. If the latching
mechanism is defective, do not use the IQ Terminator. Do not circumvent or
manipulate the latching mechanism.
When installing an IQ Cable, secure any loose cable to avoid the risk of
cable insulation abrasion against the roof surface.
When looping an IQ Cable, do not form loops smaller than 120 mm in
diameter.
Provide support for an IQ Cable every 300 mm.
If you need to remove an IQ Sealing Cap, you must use an IQ Disconnect
Tool.
When installing an IQ Cable and accessories, adhere to the following:
•
Do not expose the IQ Terminator cap or cable connections to directed,
pressurized liquid (water jets, and so on).
•
Do not expose the IQ Terminator or IQ Cable to continuous immersion.
