PX4000
The Pramac PX4000 is built for buyers who want a capable portable generator without the complexity of a full industrial installation. Its 2700 W maximum and 2300 W continuous output provides useful capacity for home backup, trade equipment, pumps, small-business loads and temporary power. AVR voltage regulation supports steady output for common tools and appliances. The portable frame keeps the unit flexible for jobs where power needs to move with the work. The recoil starting arrangement keeps operation simple for the intended use.

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.
