光伏逆变器为何要做到1500V？“光伏1500V”电压等级如何认证？

技术问答

现在 “光伏1500V”这个词被反复提及，很少见到全行业各个环节不约而同的谈到同一个技术名词。为何“光伏1500V”被提及的频率越来越高？1500V光伏系统时代真的要来了吗？

“光伏1500V”到底是什么？

“光伏1500V”说的是电压等级。目前主流的光伏电站设计以及光伏组件、逆变器、汇流箱、线缆等产品均基于直流端1000V的电压要求设计和制造。光伏电站要降本增效，升高电压时降低线损的有效措施之一。有专家提出，“从系统的角度来看，更高的输入、输出电压等级，可以降低交直流侧线损及变压器低压侧绕组的损耗，电站的系统效率预期可以提升1.5%~2%。同时，设备（逆变器、变压器）的功率密度提供，体积减小，运输、维护等方面工作量也减少，有利于光伏系统成本的降低。”

光伏逆变器为何要做到1500V？

将直流端做到1500V，最主要的原因及优势是可以串接更多的数量，从此来节约整体的制造成本，当然难点是现在可以选择的1500V输入电压范围的逆变器比较少，很多设计院在设计电站方案的时候，也是才慢慢考虑1500V，当毋庸置疑的是这必将是今后的发展趋势。

举例：以10MW光伏电站为例

基于上图可知：10MW光伏电站，1500V系统相较于1000V系统可减少使用568个组串，28个汇流箱，约减少$77390成本。另外由于组串数量的减少，人工成本也可以得到降低。但是随着系统直流电压的提升，原本应用在光伏系统内的元器件也无法满足1500V的电气要求，且目前国内外光伏组件的生产厂家的主要生产精力都放在1000V系列上，能满足1500V的光伏组件寥寥无几，这也给1500V光伏系统的推广带来了一定的难度。目前世强代理的魏德米勒产品线有两款光伏组件的电气性能能够满足1500V光伏逆变器的高标准，推荐给大家：

1、WM4C连接器，不光可以承受1500V的直流高压，还带有IP67的防护等级，且安装简单，可以更加高效，安全的连接太阳能电池板。

2、VPU II3（R）PV 浪涌保护器，也可应用在1500V光伏系统内，且-40°C~70°C的工作温度，能够在更加极端的环境下给我们的光伏系统提供保障。

“光伏1500V”电压等级如何认证？

早在2015年4月21日，德国莱茵TUV集团就在上海举办了“光伏组件/零部件1500V认证”专题研讨会，与来自全国光伏行业的客户共同分享了有关1500V光伏组件的最新认证信息、技术要求以及应对策略，以帮助客户深入了解该革命性变化（系统电压提升至1500V）所带来的技术难点，引导各大光伏组件厂商有效应对新的技术需求。

最大的难点还是置于光伏逆变器的测试认证，因为很少有检测仪器可能直接测到1500V，这也是目前市场上的技术缺口。目前世强代理的KEYSIGHT仪器中有一款太阳能模拟电源（N8957APV）可以用来测试中大型太阳能逆变器，1500V的输出电压，可以完美的应用于1500V光伏系统的测试。
