Delta’s M80U is the industry’s only 80kW inverter with an optimal cost and performance profile and the highest power density available in a string inverter. Along with the M60U, Delta’s largest string inverters provide unbeaten performance and the industry’s lowest Levelized Cost of Energy (LCOE), making them optimal building blocks for Commercial, Industrial and Utility-Scale installations.

With best-in-class efficiency, a rugged enclosure, and proven reliability, the M80U and M60U provide higher returns for your project. Designed, engineered and manufactured by Delta, you can depend on Delta’s best-in-class engineering and quality manufacturing.

The grid-tied, three-phase, transformerless inverters are designed for ease of installation fast commissioning, efficient servicing, and higher uptime.
