Technical datasheet Electrifying Innovations Utility scale - start where others give up Innovativ cooling system ProPessional project support ProPitability through service When the electrical performance parameters reach rang- es reserved for [arge-scaie systems, nothing surpasses the REFUso/ 500K-630K inverters. Their use begins where oth- ers reach their limits. They bring together almost 50 years of experience in power electronics and control cabinet con- struction with current developments from the 21st centu- ry, such as the fast and precise MPP tracking system used in REFUso/models 008K-023K. The REFUso/630K has an active cool- ing system which uses external water/air heat exchangers. For the 500K this feature is available as an optional extra. Both de- vices are equipped with anti-islanding functionality Solid in construction, robust in operation, precise in align- ment - REFUso/ also impresses in the upper power classes. And we embrace our efficiency principle here too, where huge currents of up to 1300 A flow. The peak efficiency of this central inverter is over 98.1%, with a European efficiency of 97.6% and an MPPT range from 460 to 850 V. Even at extreme- ly high power levels we understand how to make careful use Power supply Overvoltage Power circuit protection breaker Control voltages choke tactor
