General Descriptions:
SG330KTL is using low-frequency isolation transformer for protective purpose. Its wider input voltage range ensures more combinations of the PV arrays. Moreover, optical fiber isolation technology has been adopted to increase its anti-interference ability under the circumstances of multiple inverters installation. In addition, optimized circuit and structural design has improved system thermal efficiency which enhancing system reliability and stability. Reinforced protection functions, including the DC ground fault protection, make it the best product for large scale PV power plant.
