Enphase IQ8PLUS-72-M-US Microinverter

Enphase IQ8PLUS-72-M-US Microinverter
 
The Enphase IQ8PLUS-72-M-US Microinverter delivers 290VA (290W equivalent) of continuous output power for high-performance solar panels up to 440W. Designed for residential 240VAC grid-tied systems, it features MC4 connectors, Enphase monitoring integration, and NEC 690.12 rapid shutdown compliance. Built to last with a NEMA 6 outdoor-rated enclosure and advanced grid support functionality.
What is the right Enphase microinverter for my panel size?
If you're pairing this inverter with a 400W panel, the IQ8PLUS will work, but it may clip power above 290W during peak sun hours. This is normal and common in system design. For maximum output, consider the IQ8A or IQ8H for higher-capacity support.
Recommended inverter by panel size:
300W–350W: IQ8, IQ8PLUS
360W–420W: IQ8M, IQ8A
425W+: IQ8H
