Enphase IQ8+ Microinverter 290 VA Continuous AC Output – IQ8PLUS-72-M-US

Power your solar system with one of the industry's most advanced microinverters. The Enphase IQ8+ Microinverter is designed to maximize energy production on a module-by-module basis while delivering exceptional reliability, safety, and long-term performance.

Compatible with today's high-output solar panels, the IQ8+ features Enphase's revolutionary microgrid-forming technology, allowing compatible systems equipped with an IQ System Controller 2 and IQ Batteries to continue producing solar power during a grid outage.

As part of the Enphase Energy System, the IQ8+ seamlessly integrates with the IQ Gateway, IQ Batteries, and the Enphase App, providing industry-leading monitoring, system diagnostics, and remote software updates.

Built with integrated MC4 connectors and simple plug-and-play installation, it's the ideal choice for new residential solar installations and premium rooftop upgrades.

Why Choose the Enphase IQ8+?

Unlike traditional string inverters, each IQ8+ microinverter operates independently, allowing every solar panel to perform at its maximum potential. If one panel is shaded or underperforming, the rest of your system continues producing normally.

Additional advantages include:

• Module-level Maximum Power Point Tracking (MPPT)
• Industry-leading 97.7% peak efficiency
• Software-defined microgrid-forming technology
• Compatible with high-power solar modules up to 440W (typical pairing)
• Integrated Stäubli MC4 connectors for faster installation
• Natural convection cooling with no fans
• Module-level monitoring through the Enphase App
• Remote firmware updates for evolving utility requirements
• Up to a 25-year limited warranty
• UL Listed as PV Rapid Shutdown Equipment when installed per manufacturer instructions

Built for Reliable Energy Production

The IQ8+ utilizes Enphase's proprietary ASIC semiconductor technology, enabling rapid response to changing grid conditions while supporting both grid-tied operation and backup power applications in compatible Enphase Energy Systems.

Key performance highlights include:

• 290 VA continuous AC output
• 300 VA peak output
• 97.7% peak efficiency
• 97% CEC weighted efficiency
• 12A maximum continuous DC input current
• 60V maximum DC input voltage
• Wide MPPT operating range of 27–45V
• Optimized for modern 54-cell, 60-cell, 66-cell, and 72-cell solar modules.

Pair with the Complete Enphase Energy System

Frequently Asked Questions

Can the IQ8+ provide backup power?

Yes. When paired with an Enphase IQ System Controller 2 and compatible IQ Batteries, the IQ8+ can continue producing solar energy during grid outages as part of an Enphase backup system.

What size solar panels work best?

The IQ8+ is commonly paired with solar modules ranging from 235W to 440W, making it an excellent match for today's most popular residential panels.

Can I mix IQ8+ microinverters with IQ7 microinverters?

No. IQ8 Series microinverters cannot be mixed with previous Enphase generations (IQ7, IQ6, etc.) within the same system.
