GDW550V
Protect operations from costly outages with the Pramac GDW550V. Rated at 506 kVA prime and 556.9 kVA standby, 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 Volvo TAD1346GE engine and Mecc Alte ECO40 1L4 C alternator form a well-matched mechanical and electrical package 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. Order the standard package or specify a custom build with a stainless-steel canopy, hot-dip galvanised skid base, super-silent enclosure, synchronising controls or an open generator set. Talk to Capital Power Systems about generator sizing, transfer switching, fuel autonomy, acoustic treatment and a complete turnkey installation.

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.
