S280 Microinverter

In stock

The new Enphase S280™ Microinverters on IQ 7™ platform allow easy replacement and site expansion* (refer to documentation) of 240 VAC and 208 VAC S-Series PV installations. The DC circuit is isolated and insulated from ground, so no Ground Electrode Conductor (GEC) is required for the microinverter. This simplifies installation, enhances safety, and saves on labor and materials costs.

The Enphase S230 and S280 integrate perfectly with the Engage Cable™, the Envoy-S™ Communications Gateway, and Enphase Enlighten™ monitoring and analysis software. They are also compatible with storage systems, including battery management systems.

The IQ platform microinverters extend reliability standards set forth by previous generations and undergo over a million hours of testing, enabling Enphase to provide an industry-leading warranty of up to 25 years.

Note: *This product requires installation by a certified installer. At checkout, you can request matching to an installer in your area.
