Solcon soft starteri dizajnirani su za glatko pokretanje i zaustavljanje asinhronih motora, značajno smanjujući struju pokretanja i poremećaje u mreži. Kontroliranjem pokretanja i zaustavljanja, motor i opterećenje mogu se precizno uskladiti, sprječavajući mehanička preopterećenja poput vodenog udara, prenaprezanja remena i prekomjernog momenta na spojkama i osovinama. Solcon soft startereri također besprijekorno rade u nestabilnim električnim mrežama, što ih čini prikladnima za upotrebu u rudnicima, brodogradnji, vodovodnim sustavima i industriji.
