When is Enphase the right choice?
When the roof faces several directions, has chimneys, pergolas or trees casting shade, or is spread across several levels. With one microinverter per panel, a shaded panel does not pull down the rest of the system.
How microinverters work
A conventional system connects panels in strings to one central inverter. An Enphase system puts a small inverter behind each panel, converting to AC on the roof. That means panels on different roof planes can be combined freely, shade affects only the panels it falls on, and you can see each panel's output in the Enphase app.
Safety and expansion
Because there is no high-voltage DC string running into the house, Enphase systems are simple to extend panel by panel later on.
Enphase IQ Battery
Enphase batteries are modular, so capacity can be added in steps. They integrate with the same app and, with the right system controller, can provide backup.
Is it more expensive?
Microinverters usually cost more than a single string inverter for a simple, unshaded south roof. On complex roofs the extra production and flexibility often make up the difference. We quote both where it is a close call.
Questions we are often asked
Is Enphase worth it on a simple south-facing roof?
Often a good string or hybrid inverter is better value there. Enphase earns its place on complex or shaded roofs.
Can I add an Enphase battery later?
Yes. Enphase batteries are modular and can be added to an Enphase system later.
Can I see each panel's output?
Yes, in the Enphase app.
