Power Electronics recently launched Freesun HEC+, the second generation of their Freesun HEC outdoor modular and redundant inverters. The utility-scale, 1000 Vdc class inverters range from 400 kVA to 1700 kVA and offer extended MPPT voltage range and maximum efficiency in three AC output voltages: 360 Vac, 380 Vac and 400 Vac.
The Freesun HEC and HEC+ feature an outdoor IP54 stainless steel enclosure, 50 mm rockwool isolation panel and an advanced iCOOL filter-less system that makes it suitable for the most demanding conditions.
Freesun HEC can be equipped with customized internal (HEC+) or external DC disconnection and protection subsystem that makes it compatible with any PV plant configuration and the highest DC to AC ratios.
