Remarks
①
BAT
DC input terminal
It is used to connect with inverter.
②
COM.
Connect with
inverter
Connect to COM port of inverter to
communicate with inverter.
③
/
Connect to the external grounding or
grounding of the inverter.
When the DC SWITCH and COM. are not selected, the corresponding port is filled with a waterproof
plug
DC switch
DC switch (as shown in the
①
ofFigure2-8) is the connection switch of inverter and PV array.
When the inverter works normally, the DC switch must be ON. During installation and wiring, the
DC switch must be OFF. Before maintenance, the DC switch must be OFF for 5 minutes, and
measure the voltage of DC busbar by multimeter, only when the voltage less than 10V, the
maintenance can be done.
When maintenance or wiring, the DC switch must be disconnected.

#580VK can be applied in DC-coupled systems (mostly new installation),
AC-coupled systems (mostly retrofit) and hybrid-coupled systems (mostly retrofit, and PV capacity
-increase), as shown in Figure2-10, Figure2-11and Figure2-12.
