Pramac GA 20000 400V AVR gas generator

The Pramac GA 20000 AVR 400V is a gas-powered generator designed for automatic backup power supply, intended for premises where a full three-phase power supply is required rather than a single-phase one. The model is well suited to large private homes, cottages with three-phase supply, workshops, service premises, commercial buildings, technical facilities and small businesses, where it is important to ensure a stable backup power supply for three-phase loads and engineering systems.

The generator operates on a 400 V three-phase network at a frequency of 50 Hz. A key feature of this model is that its power output depends on the type of fuel: it is 17,000 VA when running on natural gas and 20,000 VA when running on propane. This is precisely why this model offers greater flexibility in choosing an energy source and allows you to select a configuration suited to actual operating conditions, load balance and fuel availability at a specific site.

At the heart of the system is a Generac G-FORCE 1000 SERIES engine with a displacement of 999 cm³. This is an air-cooled OHV engine with electric start and electronic speed control, designed for stable standby operation. The engine design focuses on durability and reliable operation in automatic mode, whilst the full-pressure lubrication system, low-oil-pressure protection and overheating protection help reduce the risk of emergency shutdowns and premature wear.

The GA 20000 AVR 400V is a model designed for scenarios where not only power but also power quality is important. Thanks to the AVR, the generator maintains a stable voltage, whilst True Power Technology ensures low levels of harmonic distortion. This is particularly useful for equipment sensitive to power quality: automatic systems, modern electronics, pumps, boilers, control modules, security systems, lighting and other critical loads.

Monitoring and control are based on the Evolution digital controller with an LCD display, backlighting, LED status and service interval indicators, Auto/Manual/Off modes, operating hours display, event logs and a wide range of protection features. The generator monitors the mains supply, supports automatic start-up, and features protection against overload, battery issues, overheating, voltage fluctuations, overspeed and other critical situations. All this makes the backup power supply more manageable, safer and more predictable.

Another strong point of the model is its modern connectivity and control features. Wi-Fi and Mobile Link are included as standard, so the generator’s status can be monitored remotely via an app. This is particularly convenient for homes and commercial premises where the owner or maintenance staff are not always in the immediate vicinity of the generator. This setup enhances user convenience and helps to respond more quickly to notifications regarding the system’s status.

The generator is housed in a soundproof aluminium enclosure, which provides good protection against the elements and is suitable for outdoor installation. The housing has a neat, compact design, and access to components has been thoughtfully designed with servicing in mind. For a three-phase backup solution of this class, this is important, as the generator must not only be powerful but also convenient for everyday use.

The Pramac GA 20000 AVR 400V is a practical option for those who need an automatic three-phase gas-powered backup system with good control, modern monitoring functions and fuel flexibility. It is suitable for facilities where backup power should not be a temporary compromise, but a fully-fledged, reliable part of the engineering infrastructure.
