Madden 4.2kW Petrol Inverter Generator MAGE4500

The Madden MAGE4500 is a 4.2 kW petrol inverter generator.

Inverter output is conditioned rather than taken directly from the alternator, which makes it suited to electronics, chargers and control gear that a conventional set of this size can disturb. It also runs at variable speed, dropping back when demand falls, so it is quieter and more economical at part load than a fixed-speed machine.

4.2 kW is a practical middle rating — comfortable for tools, lighting and a small welfare unit, short of what a 110 V transformer plus several tools will pull at once. The sizing guide covers how to add your loads up before deciding.
