Genset Engine Start

SENS is the industry’s leading supplier of genset engine starting chargers and best battery selectors. Engine generator sets (gensets) generate power for many buildings, industrial facilities, venues,  and military sites when utility power is unavailable.

Industrial DC Power

Power generators, electric utilities, and industrial plants operate a vast array of protective relays, circuit breakers, switchgear, and control electronics that keep all that power under control, preventing malfunctions from turning into high-powered disasters.

Battery Monitoring

Remote battery monitoring can save maintenance costs, predict impending battery failures and extend battery service life. Our systems can extend their monitoring and control capabilities to generators, chargers/inverters, HVAC systems, and building monitoring.
