For over four decades Northern Lights has been manufacturing generator sets proven to withstand the extremes of the Arctic North Slope to the deserts of the Middle East. RES provides reliable and efficient backup power generation to augment an off grid system using these quality generators. High copper content within the brushless generator end enables motor starting. The hand-wound, skewed stator makes electricity with a symmetrical sine wave for today's sensitive electrical equipment. The generators are designed for portable, prime or standby applications and each model meets the US EPA Tier II emissions standards. Every unit arrives factory tested and ready to connect to your system.
