中国存储解决方案专家江苏为恒智能科技有限公司发布了一系列新的工业和商业用储能系统。PowerCore系列50 kW/100 kWh产品包括四种型号,每种型号都集成了存储器和混合逆变器。
该公司在一份声明中表示:“新系统最多可实现6个单位平行并/离网,以满足不同的储能容量需求。凭借10毫秒的无缝切换时间,新系统可确保工厂生产线和农场灌溉系统等关键负载的不间断运行。新系统的紧凑结构和静音设计,使其能够在社区和办公楼等不同环境中进行灵活集成,此外,新系统还能兼容柴油发电机。”
第一款型号的光伏输入功率为59.8 kW,交流输出功率为29.9 kW。第二款型号的输入功率为60 kW,输出功率为30 kW。功率最大的两个型号分别支持80 kW和96 kW的光伏输入功率,并提供40 kW和50 kW的输出功率。整个系列产品的存储容量从57 kWh至100 kWh不等。
江苏为恒智能科技有限公司表示,新系统包含四个最大功率点跟踪器(MPPT),拥有20 A的单串光伏输入电流,可支持200%的光伏过载,这些性能使其能够适应复杂的屋顶条件并提高太阳能利用率。新系统还支持100%三相不平衡输出,以管理不均匀负载条件并增加自用消耗量。
新产品的尺寸为1,070毫米× 1,150毫米× 2,250毫米,重量约1.2吨。系统的工作温度为零下20摄氏度至零上55摄氏度,最高工作海拔为2000米。电池柜防护等级为IP55,逆变器防护等级为IP66。
