Grid-tie solar inverter Refusol 500K

When the electrical performance parameters must reach range,
reserved for large-scale systems, nothing surpasses inverters REFUsol 500K-630K. Their application begins where others reach their limits. They represent almost 50 years experience in the field of power electronics and control cabinet construction to current events, such as fast and accurate system for tracking the maximum power point used in models of 008K-023K. Both devices have effective cooling water - at 630K models even with the compressor. Both devices are equipped with anti-partitioned function
reliable, accurate alignment in -. REFUsol also impresses in high power. And we apply our principle of effectiveness and here, where huge currents up to 1300 A. The maximum efficiency of this central inverter is more than 98.1%, the European ffektivnost - 97.6%, and the tracking range of the point of maximum power from 460 to 850 V. Even at very high power levels, we understand how to make careful use of resources
