Description
The range has four models, SC 4000 UP, SC 4200 UP, SC 4400 UP and SC 4600 UP, with nominal AC voltages from 600 to 690 V. The array lands on 24 double-pole or 32 single-pole fused inputs, with a maximum DC current of 4,750 A. A DC/AC ratio of up to 200% lets the array be much larger than the inverter rating. OptiCool moves 6,500 m³/h of air, the electronics are IP54 and the duct and connection area IP34. DC load-break switch, AC breaker and type I + II surge arresters are built in, and an 8.4 kVA transformer feeds the auxiliaries. It ships alone or pre-assembled into a medium-voltage station, with a stated service life of over 25 years.
How to choose
Match the model to the LV winding of the step-up transformer, 600 V for the SC 4000 UP and 690 V for the SC 4600 UP. For a hot site, size by the 50 °C rating, not the 35 °C nameplate. For a BESS beside the plant, the Sunny Central Storage fits the same voltage class, up to 4,600 kVA as UP-XT and 5,000 kVA as UP-S. A field split into scattered blocks suits the Sunny Highpower PEAK3 string inverter, 180 kW at the same 1,500 V DC.
