Enphase IQ Cable accessories
The IQ Cable is available with several accessory options for ease of installation, including:
•
IQ Field Wireable Connectors (male): (Q-CONN-10M) Make connections from any field wireable female
connector.
•
IQ Field Wireable Connectors (female): (Q-CONN-10F) Make connections from any IQ Cable open
connector or Field Wireable male connector.
•
IQ Cable Clips: (Q-CLIP-100) To fasten cabling to the racking or to secure looped cabling.
•
IQ Disconnect Tool: (Q-DISC-10) Disconnect Tool for IQ Cable connectors, DC connectors, and AC
module mount.
•
IQ Cable Sealing Cap (female): (Q-SEAL-10) One needed to cover each unused connector on the cabling.
•
IQ Terminator: (Q-TERM-10) One for each AC cable segment end; typically, two are needed per branch
circuit.
Technical considerations
Be sure to apply the following when installing the Enphase IQ8 Series Microinverter System:
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.
WARNING: Risk of equipment damage. The maximum open circuit voltage of the PV module
must not exceed the specified maximum input voltage of the Enphase microinverter.
•
PV modules must have conductors labeled "PV Wire" or "PV Cable" to comply with NEC for Ungrounded PV
Power Systems.
•
Verify that the voltage and current specifications of the PV module match those of the microinverter.
•
The PV module's maximum short circuit current rating must be equal to or less than the microinverter's
maximum input DC short circuit current rating.
The output voltage and current of the PV module depend on the quantity, size, and temperature of the PV cells, as
well as the insolation of each cell. The highest PV module output voltage occurs when the temperature of the cells
is the lowest and the PV module is at an open circuit (not operating).
Bifacial modules
Enphase IQ8 Series Microinverters are compatible with bifacial PV modules if the temperature-adjusted electrical
parameters (maximum power, voltage, and current) of the modules, considering the electrical parameters,
including the bifacial gain, are within the allowable microinverter input parameters range. In evaluating the amount
of bifacial gain, follow the recommendations of the module manufacturers.
Bifacial solar modules produce power from both sides of a bifacial module, increasing total energy generation. The
power gained from the rear side (bifacial gain) is highly influenced by various design factors such as albedo,
module elevation, pitch, temperature, and shading. The bifacial gain can be anywhere between 0% to 30% of the
module's nominal (front-side power rating). Since various design considerations highly influence the bifacial gain,
pairing the bifacial module with the right microinverter depends on the electrical characteristics of a given
module.
