Pramac GA13000 LPG / Natural Gas Standby Generator
The Pramac GA13000 is a dependable automatic standby generator designed to provide peace of mind when the mains electricity supply fails.
Suitable for residential properties and small businesses, the GA13000 can operate on either LPG or natural gas, providing a practical alternative to petrol or diesel standby generators. Once connected to a compatible Automatic Transfer Switch, the generator can detect a mains power failure, start automatically and restore power to the connected circuits within a short period of time.
When the mains supply returns, the system transfers the property back to utility power before safely shutting the generator down. This automatic operation means there is no need to manually start the generator during an outage.
Powered by a Generac G-Force OHV engine, the GA13000 is engineered specifically for standby power applications. Its durable construction and pressure-lubricated design support reliable performance and long service intervals.
True Power™ electrical technology produces less than 5% Total Harmonic Distortion, helping provide clean and stable power for sensitive electronics, appliances and modern household equipment.
Automatic Voltage Regulation maintains the output voltage to within approximately ±1%, helping prevent damaging voltage fluctuations and supporting consistent power delivery as the electrical demand changes.
The sound-attenuated aluminium enclosure protects the internal components while helping reduce operating noise. Its corrosion-resistant construction makes it suitable for permanent outdoor installation when fitted and commissioned correctly.
The integrated Evolution™ controller features a two-line multilingual LCD display, system status information and maintenance interval indicators. This allows the generator’s operating condition and service requirements to be checked quickly and easily.
Mobile Link™ cellular monitoring provides remote access to generator information from a compatible device. Users can check the generator’s status, receive notifications and monitor maintenance requirements without needing to be beside the unit.

The Automatic Transfer Switch is an optional extra and must be selected according to the installation and electrical requirements of the property.
