Frequently asked questions
Can I run sensitive electronics?
Yes—thanks to the AVR holding voltage within ±1%, the XL-DK-11S is suitable for most sensitive loads. Always size the generator correctly and consider surge loads.
Can it switch on automatically during a power cut?
Yes—add an Automatic Transfer Switch (ATS) to enable automatic changeover between mains and generator.
How noisy is it?
Rated 68 dB(A) at 7 m in free-field conditions. Ultra-low-noise canopy options are available if further reduction is needed.
What’s the runtime?
At 100% load the engine uses approx. 2.3 L/hr; with the 25 L tank that’s around 10.8 hours. Expect longer runtime at typical part-loads.
