If you want to prepare for a prolonged blackout, you are well advised to use a mobile power generator. In terms of power class, a generator should have a continuous output of more than 2000 watts. This means you are on the safe side and can also operate appliances such as electric hotplates, a fully automatic coffee machine, refrigerators and freezers and much more. To be able to operate sensitive devices with electronics, such as a Smart TV set or similar, a generator with inverter technology is recommended. These generators produce alternating current with a constant sine wave of 50 Hz. That’s why we chose the Crosstools CPG 3000inv as our recommendation for a corresponding test in the article “Inverter power generator comparison“.
Crosstools CPG 3000inv – Inverter-Generator
With inverter technology, the Crosstools CPG 3000inv promises a clean voltage and is thus also suitable for operating sensitive electronic devices such as computers, laptops or televisions. The generator delivers a continuous power of 2,600 W and a short-term peak power of 2,800 W. The generator has two standard 230 V earthed sockets, as well as two 12 V sockets. The tank holds 7 litres of petrol. With a consumption at half load of about 0.7 litres per hour, the generator can be operated for about 9 hours with one tank filling. The current voltage, as well as the amperage and the electrical power output are displayed on an illuminated LC display. In addition, there is also an operating hours counter.
Eco mode for particularly economical and low-noise operation
The generator can also be set to an eco mode via a toggle switch. In eco mode, the combustion engine adjusts its speed to the power of the consumer. This not only reduces consumption, but also the noise level. Of course, the Crosstools CPG 3000inv has all the safety features, such as overload protection and low oil monitoring. The inverter generator weighs approx. 28 kilograms. The manufacturer gives a 2-year guarantee.
The scope of delivery includes a 12 V charging cable for charging a car battery, a spare spark plug and the tools needed to change the plug. Also included is an oil measuring cup with a filling snorkel and a special drain pipe for an oil change. There is also a detailed instruction manual in German.
For commissioning, one must first fill the generator with oil and petrol. However, the required engine oil with the specification SAE 10-W40 is not included in the scope of delivery. To fill the oil, one must first open the maintenance flap with the tool provided. Filling the required oil quantity of 0.45 litres is easily possible with the supplied oil measuring cup. At the first start, it took a little longer for the engine to start. After that, the fuel system is sufficiently filled with petrol and the engine starts at the latest with the second pull on the pull-starter. The engine is very quiet when idling and can hardly be heard at a distance of a few metres in eco mode.
Powerful generator leaves nothing to be desired
For the test, we connected various appliances. First, a kettle with a power consumption of 2.5 KW. The generator easily copes with this, even if it has to step on the gas quite a bit in eco mode. Nevertheless, the noise level remains comparably low. Next, we connected an induction hotplate with two hobs. Both hot plates together have a power consumption of 2.7 KW. The Crosstools CPG 3000inv also masters the test with both hot plates simultaneously at maximum power without any problems, although the total power is already slightly above the specified continuous power.
Operation of a washing machine and tumble dryer is possible without any problems
The endurance test was a washing machine with 7 kg of laundry in the hygiene programme, i.e. with a long high temperature. This was no problem for the generator, nor was the subsequent drying of the laundry in a tumble dryer. In total, the generator consumed just under 1.5 litres of petrol for both processes after a good 4 hours of operation.
At 28 kilograms, the Crosstools inverter generator is relatively light in its power class, but it is no lightweight. It only has a sturdy carrying handle and has no transport wheels like similar makes. However, this is the only suggestion we could make to the manufacturer to improve its product. Otherwise, the Corosstools CPG 3000inv met all our expectations with flying colours.
