Pros
- 380 W of continuous output suits 450 to 540 W panels
- Each panel works on its own, so shade on one doesn’t pull down the array
- Listed for rapid shutdown, so it passes inspection without extra roof hardware
- A 25 year warranty once registered
Cons
- The 12 A input clips high current panels; the newer IQ8HC takes 14 A
- Sold only through a third party Amazon seller in our check
- Monitoring needs an IQ Gateway, sold separately

Enphase IQ8M
#6 in One panelFull review
A good match for 350 to 450 W panels on an Enphase system. Check the IQ8MC price first, since it takes more current for less.

Enphase IQ8+
#8 in One panelFull review
The common choice for 60 and 72 cell panels up to about 400 W on an Enphase system. For bigger modern panels, the IQ8HC or IQ8MC takes more current for less per watt.
