Pramac GA20000 230V Dual Fuel 9KW+ Residential Backup Generator

Pramac GA20000 230V Dual Fuel 20KW Residential Backup Generator

Introducing the Pramac GA20000 230V Dual Fuel 20KW Residential Backup Generator, a powerful and versatile 3-phase residential backup generator. Designed for reliability and efficiency, this generator is part of the renowned GA series, featuring the robust Generac G-Force engine. The Overhead Valve (OHV) engine delivers an impressive 20kVA / 20 KW of power, making it ideal for homes with medium to large appliances, heating systems, and sensitive electronic equipment. With its compact design and low noise levels, the Pramac GA20000 stands out as a leader in the LPG and Natural Gas generator market.


The Pramac GA20000 offers exceptional performance with standby power ratings of 20kVA (Liquid Propane) and 17kVA (Natural Gas). Despite its powerful output, it boasts surprisingly low fuel consumption, using just 4.50 m³/h of Natural Gas and 6.83 kg/h of LPG at 50% load. For seamless operation during power outages, an optional 100 Amps Automated Transfer Switch is available, ensuring the generator starts automatically when needed.


User control is at the forefront of the Pramac GA20000’s design, featuring a digital control panel with an hour meter, alert codes, and a programmable seven-day exerciser. Additionally, the Wi-Fi Mobile Link™ system allows for remote monitoring, keeping you informed of your generator's status anytime, anywhere. Despite its robust capabilities, the Pramac GA20000 operates quietly at 65 dBA from a distance of 7 meters, making it a discreet addition to any residential setup.
