The SDEC 30 kVA three-phase silent diesel generator (GKSD-34) is a robust, low-maintenance backup solution for homes, offices, retail, workshops and estates that can’t afford downtime. It arrives in a sound-attenuated, weather-resistant canopy and includes a fully interlocked ATS, so it starts automatically when the grid fails and switches back to mains when power returns. The SDEC 4-cylinder 3.2 L engine and StromerPower brushless alternator with AVR (SX460) deliver stable, dependable power with user-friendly control via the Smartgen HGM4020N.
