IQ8 microinverter: Intelligent, high-performance solar energy
The most intelligent microinverter to date.
The latest IQ8 microinverters are compatible with Smart Grids and designed for the latest generation of high-efficiency photovoltaic modules.
IQ8 microinverters have the highest power output and reliability in the industry and, thanks to their quick-stop functionality, meet the most stringent safety standards.
IQ8 microinverters are CE-certified and comply with various legislation only when installed in accordance with the manufacturer's instructions.
Safety first and foremost
By design, the microinverter is the safest choice for solar power. Unlike systems incorporating a central inverter, photovoltaic solar alone never contains high-voltage direct current (DC), eliminating the risk of fire.
Certified performance, rain or shine
All IQ8 microinverters are weatherproof, with IP67 certification. With their corrosion-resistant, double-insulated polymer casing, they are designed to withstand almost anything nature can throw at them.
Even greater performance

Energy in the palm of your hand
Find out how much energy you're producing, consuming and saving in real time, or view reports over a period of time. Change your system settings and get important service messages, all from a single user interface.
A responsive and responsible system
Enphase Energy Systems feature a quick-stop function so that, in the event of an emergency, solar power can be cut off easily and instantly, ensuring the safety of utility workers and first responders.
A system ready for today and tomorrow
The solar photovoltaic system is plug-and-play.
As your household's energy needs grow over the years, an installer can simply plug in more solar panels and microinverters.
A bright idea, even in low-light conditions
If shadows or clouds hang over your home, Enphase IQ8 Series microinverters use revolutionary Burst Mode technology to capture more energy in low-light conditions.
IQ Gateway (optional)
IQ8 Series microinverters integrate with IQ Gateway to keep your system fully connected to the Enphase Cloud network for remote monitoring via Enphase Apps.
IQ8 Series with integrated Type MC4 connectors
Quickly and easily connect PV modules to IQ8 Series with integrated Type MC4 connectors.
IQ Cables (optional)
Install microinverters quickly and safely with IQ Cable. With 3P IQ Cable, the installed capacity is automatically distributed evenly over the three phases.
Limited warranty
IQ microinverters are covered by an industry-leading 25-year limited warranty*.
*Valid only if an IQ Gateway connected to the Internet is installed.
How Enphase IQ microinverters work
The Enphase microinverter maximizes energy production using a sophisticated algorithm, the Power Delivery Optimizer (MPPT). Each Enphase microinverter is individually connected to a PV module in your field. This configuration allows an MPPT to control each PV module. In this way, the maximum power available from each PV module is exported to the grid without being influenced by the performance of other PV modules in the field. Even if some PV modules in the field are shaded, dirty, misaligned or mismatched, each Enphase microinverter guarantees optimum performance of its associated PV module.

Modules can be combined as long as the maximum input voltage is not exceeded and the maximum input current
of the inverter at the lowest and highest temperature is respected. |

| According to IEC60364, using an IQ Cable with a cross-section of 2.5mm², a safety factor of 1.25 is applied to the maximum permissible current. The maximum current then allowed in the IQ Cable is 16A. |
| The safety factor applied may vary depending on local regulations and also on the overcurrent protection device selected. |
| Maximum number of units per IQ Cable section single-phase / multi-phase |
| (P+N) / 21 (3P+N) |

| Center Feeding is best practice |
| This design recommendation keeps voltage rise and resistance inside the IQ Cable within acceptable limits. In areas subject to high network voltages, it may be necessary to reduce the number of microinverters per IQ Cable by up to 50%. |
