标题应该是:为什么太阳能安装人员仍然保持超过600V字符串的警惕。
hi。 installations.
But AS/NZS 4777-2024 changed to make AS/NZS 5033:2021 the reference to the maximum string size, and 600V limit is no longer a thing.
One electrician in particular mentioned that he called various parties including the Vic solar inspector who gave strong reservation on going over 600V.
One inverter I had first been quoted was the SolarEdge 15kW 3阶段的商业逆变器至少具有600V的DC输入,显然,Solaredge本人强烈建议您不要在消费者安装中使用它。
如果这是安全的事情,那么
像Solaredge Optimiser这样的事情会立即单独隔离。电压串,它的启动效率要高得多,并且可以使用更薄的电缆。
必须使用两个逆变器大大提高了价格。
我刚刚为我们的新房子和安装程序提供了580W的工作,并在其中有一些工作,并且在其中有更多的工作,并且在此方面使用了580W的cor,并且在此方面进行了更高的要求 - (ours is all going to be external to the house) but other than that there should be no reason – all the equipment is rated to at least 1000v if not 1500v for the switches etc

I have just specced up my new system for our new house and the company and installers are using 580W面板,很满意,在600V以下的600V
之间,在逆变器和额外的电缆之间增加了约4,000美元。
,我需要撞到电压窗口内的面板数量
