PV Grid Connected Inverters 250KW

General Descriptions:SG250K3 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.Technical Features: • Reactive Power Control with power factor from 0.9 lagging to 0.9 leading • German BDEW medium voltage guideline compliant • Max. efficiency at 97.3% • Easy Installation and maintanence • Multilingual touch screen monitoring and control interface • Suitable for harsh grid environment • Auxiliary heater (optional) • Max. working altitude at 6000m (operation with derating above 3000m) • High quality german brand enclosure • TÜV, CE, Enel-GUIDA certificationCommunications: •  RS485/Ethernet interfaces •  Computer monitoring softwareSafety: •  Full protection functions: over-voltage protection, short-circuit protection, islanding protection, over-heat protectionover-load protection, DC ground-fault protection •  Standards complied: EN61000-6-1, EN61000-6-2, EN61000-6-3, EN61000-6-4,EN61000-3-2, EN61000-3-3, EN60164-1-1,EN55022, EN50178, TÜV, Enel-GUIDA
