GT Power GTi20000G5 5th Generation Battery 20,000W Portable Power Station

GT Power 5th Generation Battery 20,000W Portable Power Station

The GT Power GTi20000G5 Portable Power Station is a heavy-duty battery power solution designed for construction, civil works, agriculture, emergency response and industrial applications. Its 5th Generation NCA lithium battery delivers 3600W continuous power with up to 20,000W surge output, providing the starting capacity needed for demanding tools, compressors and welding equipment. With no exhaust fumes and operating noise below 30dB, it provides a practical alternative to petrol generators where quiet, emission-free power is required.

20,000W Surge Power
With up to 20,000W surge and 3600W continuous output, the GTi20000G5 provides substantial starting power for heavy motors, compressors, welders and demanding worksite equipment.

5th Generation NCA Lithium Battery
The 2304Wh NCA lithium battery combines high energy density with an advanced Battery Management System, helping maximise performance and battery lifespan in demanding professional applications.

Silent, Zero-Emission Operation
Operating below 30dB with no exhaust fumes, the power station is suited to indoor sites, residential areas and industrial environments where noise or petrol-powered generators may be restricted.

Proven Welding Performance
Designed for real-world trade use, the GTi20000G5 has been independently tested at a continuous 100A welding arc for 30 minutes, equivalent to approximately 25 × 2.5mm GP welding electrodes.

Fast AC Mains Charging
An approximate 2.2-hour AC mains charging time helps reduce downtime between jobs, while instant-on battery power eliminates the starting, fuelling and warm-up requirements associated with combustion generators.

Advanced BMS Protection
Integrated battery management provides protection against over-temperature, over-current, short circuit and over-voltage conditions, supporting safer and more reliable operation on demanding jobsites.

Rugged Worksite Construction
A reinforced welded steel chassis is engineered for demanding commercial and industrial environments, helping protect the battery system against the knocks and conditions encountered during worksite use.

Portable High-Capacity Power
At 24kg with two 230V AC outlets, the GTi20000G5 combines substantial output with transportable power for construction, civil works, agriculture and emergency-response applications.
