Manufacturer Enphase

This new fourth generation micro-inverter has an outstanding 97.0% CEC efficiency, an increased output power of 280W AC and is compatible with 60 cell solar panels up to 365W. Enphase has insulated and isolated the DC conductors from ground removing the need to install a separate grounding electrode conductor (GEC) to each unit resulting in a simplified, safer and more economical installation. Adding Enphase S280's to your system will truly optimize the amount of power gathered.

The S280's also include advanced features to detect ground faults which often go undetected with other micro-inverters. These units are extremely lightweight, weighing in at just over 4 pounds and easy to install with the plug-and-play Engage™ cables.

The company proudly stands behind the S280 with a solid 25-year limited warranty.
