GBW15P
Protect operations from costly outages with the Pramac GBW15P. Rated at 11.5 kW prime, it is designed for commercial standby, industrial backup and site power. The set can be matched to the real load, motor-starting demands and operating environment rather than selected on nameplate size alone. The Perkins 403A-15G1 engine provides a recognised power platform for long-term standby or prime-power service. Integrate it with automatic transfer switching, remote monitoring, distribution and site fuel systems to create a complete power solution. Capital Power Systems can assist with load assessment, ATS selection, fuel systems, exhaust, installation, testing and commissioning across Australia.
- Diesel generator for standby or prime power applications
- Configurable canopy, controller and fuel-tank options
- Electric start and generator control-panel integration
- Designed for commercial, industrial and facility backup power
Compatible with GBW15P. A 5% accessory discount is applied automatically when bundled with this generator.

Pramac
Pramac is a leading global manufacturer of stationary and mobile power generation equipment, founded in Casole d'Elsa, Tuscany in 1966. Now part of the Generac group, Pramac engineers diesel, petrol and battery energy storage solutions trusted by rental houses, mining sites and emergency services in over 150 countries.
Deep Sea Electronics
Deep Sea Electronics (DSE) has been designing intelligent generator and battery management controllers from Hunmanby, UK since 1975. Their controllers — including the iconic DSE 4520, 6020 and 7320 series — set the global standard for AMF / ATS automation, remote monitoring and over-current protection.
Perkins — Engine
Perkins is a British diesel engine manufacturer (part of Caterpillar Inc. since 1998), with engines in production since 1932 and over 22 million units built. Perkins powers the bulk of industrial-class Pramac generators — the 1100, 1300, 1700, 2200, 2500, and 4000 Series engines have a global service network and a reputation for reliability under continuous and prime-power duty cycles.

Almost every conversation about generator sizing starts with two numbers: kVA and kW. They sound similar, they're closely related, and they're almost always mis-used. The beer-glass analogy below is the fastest way to get them straight in your head — and once you do, every spec sheet in the catalogue suddenly makes sense.

A generator is really three machines bolted together: an engine, an alternator, and a controller. They each do one job, and they all have to talk to each other for the unit to behave properly.

Almost every customer who asks us 'should I get diesel or petrol?' gets the same answer: it depends on the duty. For occasional camp / weekend use under 8 kVA, petrol is cheaper to buy and lighter to move. For anything that has to start reliably after sitting unused — backup, standby, prime-power — diesel wins, almost always.
