The other argument, Tom, is that it is easy for someone like BP to drop one of its many product lines and keep all of its others. With no history, any new hardware will have to generalize on “mean time between failure.” I don’t know what the future holds for Enphase in particular, but someone will move module level power electronics into far more reliability. There are just too many advantages to bypass.
It’s hard to imagine that LG, Jinko and SolarWorld would choose Enphase for their AC modules, without confidence in their reliability. Westinghouse was early on in that choice, and Siemens markets rebranded versions up through at least M250 so their electronics have been evaluated by competent engineers. Siemens charges about $10 more/inverter so if you are more comfortable with a Siemens warranty that is maybe worth it. It will be telling if these companies follow beyond into the S and IQ series. I’m not sure that you’d want to trust the first inverter from any manufacturer and it gives me some assurance that Enphase is into its sixth version. We’ll give IQ’s a trial run before dropping. I think it is a gutsy company which has made a remarkable run at it. I am disappointed with their going back on their 15 year warranty and the lack of reimbursement that was initially promised.

Also in many states you and the distributor or whoever is left must replace the product IF the manufacturer goes belly up . Case in point the Chinese Sheet Rock fiasco. Noe Especially if you KNOW s company is in financial trouble AND sell their product, you can be liable because you are " in the swim " as an expert in your field and SHOULD know . That is why I advise contractors to use products like LG , Panasonic, Hyundai , etc that have more than one iron in the fire . Unfortunately some contractors in Florida are selling Suniva , old Sun Edison after they went kaput. Which is illegal since they have no warranty and a few were caught and had to take them down and then skeddale from a mad 😡 homeowner who of course wanted his money back and would not pay the final . It is tough being a contractor but when you are selling HIGH dollar contracts the owner will no doubt look for legal beagles or lawyer sharks 🦈 who love high dollar recoveries . Just be cautious in today's world . GatorTom
