Unit Description
PV Array A device which convers light energy from the sun into electricity and provide DC
power to the
Inverter
DC Disconnect Unit
(or DC Junction Unit) The “interface” between PV array and PV inverter which consist of DC breaker,
and connecting terminals.
PV Inverter A device which converts DC (Direct Current) power from PV panel(s) to AC
(Alternating Current) power..
AC Disconnect Unit
(or AC Junction Unit) The interface between Utility and PV-Inverter for the installation of protection
equipment devices required by safety standards, such as AC switch, AC
breaker, fuse and connecting terminals. To comply with local safety standards
and codes, the power system configuration should be designed and
implemented by a qualified technician.
Public Utility or Gird The infrastructure allowing electric power company to supply AC power to end
users (also referred to as “grid” in this manual). Please note that the PV-Inverter
can only connect to low-voltage systems

DC Disconnection Device
According to DIN VDE 0100-712:2006-06, a device for disconnecting Inverter from DC pow
must be installed between PV-module and the Inverter in Germany.
PV Modules Only
Do not connect any DC power sources other than PV modules to PV inverter.
WARNING!
External AC and DC disconnect device shall comply with local safety standards and codes, the
connection system should be designed and implemented by a qualified technician.
