In reply to Allan. I have Sunpower who uses Enphase micro inverters. When I have a problem, I call Sunpower not Enphase. Who is your installer?

In reply to Allan. Maybe you should contact the installer of your solar

I have a solar system connected to my house and the end phase system hasn’t worked for two months and I have tried to get endphase to come and fix it but nothing has happened. I have phoned numerous times and have promises that someone will be sent but I haven’t seen anyone yet. I am beginning to think solar is a waste of time and money. I have lost two months of productivity. What a waste. Allan

I work as a Solar Installer Supervisor/Trainer @ Grid Alternatives. I’ve been in the industry for more than 12 years an I witness the evolution of Enphase products, i remember working with micros 250, etc….. And the service calls for Enphase products are minimum… And when I reach out the team to exchange one old micro they respond really quickly, I’m looking forward to working with this new micros for commercial projects.

I am a electrician in Massachusetts and been doing it for 32 years I like the endphase product fir a numder of reasons? The inverter equipment is located at the panel versus 1 big one on the side of the building and looking hideous? What is more important is that if you have a failure of a inverter it only affects the one panel production? But the one larger unit failure you lose all the possible production of solar until final repair is made. Another factor is the termination out in the field will not fail unlike the string systems that are out there ? Because the D rating factors for a voltage drop and temperature are not done right in the field.
The connections at the pins are not rated 90° ? But the wire is But because the terminal are not rated that’s why they have a higher failure rate versus the endphase product? Many installers are cookie copy type teaching instead of looking outside of the Box.
If the endphase loads are installed at 50% of the wire capabilities plus the connections are to be the main calculation factors you will have no failures.
I could get into more specifics but it be more of my time.
Every one should only use endphase style installation and I believe it will. once everyone learns after all the problems they deal with.
