Battery inverters for large scale storage systems

Sunny Central Storage 3450 UP-XT / 3600 UP-XT / 3800 UP-XT

Battery inverters for large scale storage systems

With a max. output of up to 4600 kVA and system voltages up to 1500 V DC, the SMA Sunny Central Storage allows for more efficient and flexible system design for battery power plants. The SCS UP-XT versions allow a system design with higher output power and higher short-circuit current contribution. The intelligent cooling system OptiCool ensure smooth operation even in extreme ambient temperature.
