IQ8AC/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 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 Enphase compatibility calculator. Using an electrically
incompatible PV module voids Enphase warranty.
WARNING: Risk
of equipment
damage.
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.
WARNING: Risk
of equipment
damage.
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.
NOTES:
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.
NOTES:
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.
IQ Cable safety
DANGER: Risk of
electric shock.
Do not install the IQ Terminator while the power is connected.
WARNING: Risk
of electric shock.
Risk of fire.
When stripping the sheath from the 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 the 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.
WARNING:
Use the IQ Terminator only once. If you open the IQ Terminator following
installation, the latching mechanism is destroyed. If the latching mechanism
is defective, do not use the IQ Terminator. Do not circumvent or manipulate
the latching mechanism.
When installing the IQ Cable, secure any loose cable to avoid the risk of
cable insulation abrasion against the roof surface.
NOTES:
When looping the IQ Cable, do not form loops smaller than 120 mm in
diameter.
Provide support for the IQ Cable every 300 mm.
If you need to remove IQ Sealing Cap, you must use the IQ Disconnect Tool.
When installing the IQ Cable and accessories, adhere to the following:
• Do not expose the IQ Terminator cap or cable connections to directed,
pressurized liquid (water jets, etc.).
• Do not expose the IQ Terminator or IQ Cable to continuous immersion.
