We got the same Duo 100.
It was compleatly falling apart after only 300h of use when we got Vela Nautica.
We gave it a compleat refit what included an one DIN grade stronger AC Motor because CAT PUMP Germany said the build in AC Motor is not strong enough. And the motor shaft was worn out.
It was also needed to replace the soft pulley discs to industrial grade ones and change all bearings to high quality SKF.
The selenoid previously munted on the device did not cope with the units vibrations and was then wall mounted.
Since that its working flawless and has now about 900 hours. The unit is now almoast vibration free and is not to be heard anymore.
We use AC only when the Genset is working anyway. Otherwise we use the 24V motor. We like this oportunity to switch AC / 24 V, I think its a clever design. Only it might be wise to use higher grade spares than the original brand.
An replacement of the 220 V AC motor is not really expensive (industrial grade about 160 €) so its not worth to level motor wear.
