Hi guys,
I’m no expert but I do sell a lot of Enphase. IQ7x is primarily for commercial deployment, 72 & 96 cell panels (not compatible with 60 cell) IQ7+ are compatible with 60 & 72 cell panels. Only thing you need to worry about is oversizing more than 33.3336% which is a CEC ruling. All Enphase inverters can couple with any panel, even round ones if that ever happens lol. Don’t worry about warranty on Enphase we have over 6000 out there, over the last 10yrs and never had a warranty claim for inverters. Some issues developing on the old Envoy R’s but the new Envoy - S are awesome. As an installer we only use Envoy-S metered. And they rock.
Kind regards
