I had 4Kw of Solar panels fitted last year all with Enphase Microinverters and to be fair they have out performed my expectations, I only get very little shading on one panel first thing in the morning from a neighbours roof and none of the other panels are effected, if i had string system with a great big inverter every panel would have lost power output. this year I had a 9.5Kw Givenergy battery fitted and use Octopus flux tariff and its been brilliant I wish I had a bigger array about 6Kw would have suited me better which i will be addressing later in the year. Our home uses roughly between 7 -10Kw per day and on a sunny day I can generate between 25-27Kw, selling the rest back to energy company at peak time I get 39p per Kw which to be fair with Octopus is really great and very fair, on cloudy days i just run the house in the evening and don't export to the grid. I only recommend Enphase inverters because of my own experiences so far I haven't had any issues, but like I said I wish I had gone for a bigger array to start with, but we live and we learn.
What about adding batteries to the system is that a benefit or a disadvantage of Enphase?? Oh wait you can't add batteries to the system without having an AC coupled inverter and battery Hybrid and DC Coupled systems are, essentially, the same thing..........
Can you explain how a company who have been around for almost 20years with 7years of learnings of the product can have over 1,000,000 hours of testing on a product (1 million hours = 41,000 hours which equals 114 years) this fact meant nothing to me!
For any roof.................. sorry buts that just BS and Enphase should STOP perpetrating this untruth. 1) What are the failure rates of Enphase Microinverters? 2) Does the 25year guarantee cover the cost of the scaffolding etc etc required to replace it when it fails? In the USA self build (where enphase originally pitched their products) is commonplace and this is less of an issue as large proportions of the housing stock are single story. Multi story don't use them as they have mechanical rooms or basements to house the inverters instead. 3) Is this the same type of 25 year warranty that panel manufacturers offer? In that: A) it only covers the replacement of the failed product. eg NOT the installation costs B) They will offer a similar panel (in the event that the exact panel is no longer available) regardless of size and other important features Isc & Voc and finally C) they can offer your a proportional cost replacement of the panel's lost performance...... so if the panel fails in year 12 of 25 this means that they could in effect offer you say 50% of the panel cost as you lost half of that panels production. If the panel cost £100 then this would be £50, £200 then £100.
Hello @magicianman see below; 1) The failure rate is 1 in 2000 as advised in the video 2) No it doesn't but the 1 in 2000 risk should give some level of comfort. I wouldn't back a 2000-1 horse in a race. a) Install cost not included b) The suitable product at the time will be offered for example the IQ8 will be available soon c) A brand new product would be provided

Thanks Iggy, how much more would you have added to the system? Where in the world is it?
