Good grounded is important for resist the surge voltage shock and improve EMI's performance.
So before the connec�on of AC, DC, communica�on connec�ons, inverter needs to ground first.
For a single system, just ground the PE cable; For mul�ple machine systems, all PE cables of the
inverter need to be connected to the same grounding copper platoon to ensure the equipotent
connec�on. The installa�on of the shell ground wire is shown as.
5.3 Connec�on of the ground line
Inverter has the func�on of wireless remote monitoring inverter. The inverter has Wifi func�on
and Wifi Plug in the accessories is used to realize the connec�on between the inverter and the
network. The opera�on, installa�on, networking, APP download are detailed in the WIFI PLUG
instruc�ons. Figure 5.13 is the Internet monitoring solu�on.
5.4 Inverter monitoring connec�on
Warning:
Inverter has built-in leakage current detec�on circuit, If an external leakage
current protec�on device is connected, its opera�ng current must be greater
than 300 mA or higher, otherwise inverter may not work properly.
