The SP series diesel generator sets manufactured by SMAN are powered by our SK series diesel engines. They come equipped with an auto-starting device and an optional ATS switch cabinet, which can be used to automatically start and switchover generator sets. The sets feature high voltage regulation accuracy, excellent dynamic performance, minimal voltage wave distortion, high efficiency, and operating reliability. These generator sets offer long service lives with great fuel economy. With their maintenance-free battery starting system, the generating sets can be started by simply pouring oil and coolant into the system and flipping a switch.
