Generally Speaking,the voltage on DC side of PV system usually is higher,could be as high as 1000V DC.So we need switchgear of Ue=1000V DC.The branch circuit is combiner box needs protection,while the main circuit equipment in combiner box and DC cabinet need isolating function1.Switching with load of 1000V DC or remote operating function.in addition,it needs to install switchgear 2 on DC side of inverter cabinet ti switch with loads,plays a role of isolating for overhauling
More InfoThe product passed IEC authorized IP66 waterproof testing,also our company will take simulation tests irregularly,similar to customer's using environment,to make sure this product completely conforms IP66 protection grade.
