String Inverter System

In a conventional setup, one inverter controls the output of a whole solar array, a

design with a single point of failure.

Single pointof failure

SunPower AC Modules

SunPower AC Modules distributes this risk across every panel through a far more reliable

technology: Enphase microinverters.

Reliably Powerful

Greater reliability with no centralized point of panel failure.

String Inverter System

In a conventional setup, the system performs only as well as its weakest panel. This can dramatically reduce output due to

shade or other real-world challenges.

Each SunPower AC Module performs individually, allowing each panel to contribute up to its maximum potential for your system.
