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.

3.7/5
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.

Pros
- Works on its own during daylight outages when paired with an Enphase backup system
- 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
- A 12 A input clips the current of many 400 W+ panels on bright days
- Costs more per watt than the newer IQ8MC and IQ8HC
- Monitoring needs an IQ Gateway, sold separately

#7 in One panelFull review
For big 72 cell panels on a 240 V Enphase system. The IQ8HC does the same job with more input current and usually costs less.

#9 in One panelFull review
For 400 to 500 W panels on an Enphase system, but the IQ8AC replaces it with more input current for less money.
