Enphase IQ8H
#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.

3.6/5
For 400 to 500 W panels on an Enphase system, but the IQ8AC replaces it with more input current for less money.

Pros
- Puts out 349 W continuous, enough for 400 to 500 W panels with little clipping
- 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 is low for modern high current panels
- The newer IQ8AC has the same output, a 14 A input and usually a lower price
- Monitoring needs an IQ Gateway, sold separately

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.

#10 in One panelFull review
Only for high voltage 80 or 96 cell panels, where it is the Enphase option. Everyone else should pick the IQ8HC.
