With our tandem generator, one engine coaxially drives a single phase generator and a three-phase generator, each of which individually supply power to a different load.
Tandem generators are recommended if, in case of power failure, you want to simultaneously use a three-phase power load (such as an electric roller shutter) and a single phase load.
As the single phase and three-phase generators are electrically isolated from each other, noise and other unfavorable factors from the three-phase load will not affect the single phase load.
