Xantrex GT 2.8, GT3.3N, GT4.0N, GT5.0 Inverter

Utility grid-tie solar power inverter

The Xantrex Grid Tie Solar Inverter (GT Series) is designed to convert photovoltaic (PV) electricity produced by solar modules into utility-grade power that can be used by the home or sold to the local electrical utility. Offering high efficiency (up to 96.0 %), clean aesthetics, high reliability, and a low installed cost, through ease of installation and integrated features, the GT Series is a proven, high-frequency design in a compact enclosure.

The GT Series may be installed as a single inverter, for a single PV array, or in a multiple-inverter configuration for large PV arrays. This inverter is eligible for most state rebate programs. Contact us for information or complete systems that are eligible for rebates.
