GPW45Y
Built to earn its keep on changing jobs, the Pramac GPW45Y brings 45 kVA-class output to a mobile rental-spec package designed for fast deployment and dependable site power. It is a strong fit for construction, civil works, planned shutdowns, events and emergency support where the generator needs to be easy to position, connect and manage. The Yanmar engine gives fleet owners a familiar service platform, while the final outlet, control and fuel configuration can be matched to the intended load and operating hours. CPS can help configure outlets, control options, fuel autonomy, remote monitoring and transport requirements for your fleet or project.

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.
Yanmar — Engine
Yanmar is a Japanese engine manufacturer founded in 1912 and one of the world's most respected small-diesel engine builders. Yanmar's TNV and L-series engines are the benchmark for portable and standby generator duty — known for fuel economy, cold-start reliability, and exceptionally long service intervals. Spare parts are widely available across Australia and Yanmar service is supported nationally.

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.
