The QSV91-G Series is a high-performance natural gas generator set built on a powerful 91-liter platform, designed to meet the demands of industrial-scale continuous and standby power applications. With an output capacity exceeding 2,000 kW, this system is driven by an 18-cylinder, multi-turbo natural gas engine that delivers dependable performance, advanced load handling, and low environmental impact.

Operating at 400V / 50Hz, the genset is optimized for use in regions with 50Hz power standards, making it ideal for critical infrastructure, oil & gas, heavy industries, and remote off-grid sites. The system supports full-load acceptance without shutdown, maintains voltage and frequency stability, and meets the ISO 8528-5 G1 transient response requirements.

Built for extreme environments, it performs efficiently in high ambient temperatures and elevated altitudes, and it supports flexible fuel options — including pipeline natural gas and low methane number gases such as oilfield gas. With electrical efficiency up to 38.3% and the ability to operate on fuels with methane numbers down to 40 MN, the QSV91-G series offers a versatile, emission-compliant, and rugged solution for high-capacity natural gas power generation.
