Product Overview

GT Power GT9000ESi 9000W/11.25kVA Electric Start Silenced Inverter Generator

The GT Power GT9000ESi is a premium-grade inverter generator designed to meet the demands of professionals, solar system integrators, and serious home users. Built around a powerful Powerdyne 4-stroke OHV engine, it delivers a massive 9000W max (11.25kVA) and a continuous 8200W rated output (10.25kVA)—plenty of muscle for backup, worksites, mobile trade applications, and running high-demand appliances during outages.

Despite its power, the GT9000ESi runs whisper-quiet thanks to its silenced casing, large muffler, and smart throttle that automatically adjusts engine speed to match load requirements. This not only keeps noise levels down (just 69dBA at 50% load) but also improves fuel efficiency—ideal for extended use and minimal disruption.

Whether you're connecting directly to a solar battery bank with the two-wire auto-start function, charging electronics with pure sine wave USB outlets, or running heavy-duty tools on a remote site, this generator has all the smart features to keep your job running seamlessly.
