Connecting to the Grid
Wiring the KP100G to the Grid
The AC connection unit is an interface between PV-Inverter and the Public Utility. It may consist of an electrical breaker, fuse and terminals for
connection to both PV-Inverter and the Public Utility. This AC connection unit must be designed by qualified technician to comply with local safety
standards.
Use a 20 A trip AC breaker that matches the B trip characteristics.

Preliminary Confirmations
Check the following items before wiring.
Table 5-3 Preliminary Confirmations
No.
Inspection Item
Measurement or Confirmation
Check mark
1
Solar module installation
condition
Visual confirmation:
Refer to the installation manual for the solar modules.
2
KP100G installation condition
Visual confirmation:
Make sure none of the mounting screws are loose.
Make sure that the KP100G and the mounting base plate are securely fixed with the
main body mounting screw.
3
Wiring, connection, and
conductivity
Visual confirmation:
Inspect for looseness in plugs and screws, proper wire connection, and conductivity.
4
KP100G ground resistance
Measurement confirmation:
Standard: 100
Ω
max.
KP100G actual measurement:
Ω
5
Voltage measurement for each
solar module string
(See Note 1.)
Measurement confirmation:
V
Measure to confirm that the grid voltage is 230 V.
6
Grid voltage confirmation
Actual measurement: V
Note 1: The output voltage of the solar modules varies depending on their type and the number connected in series. Confirm that the voltage difference
between adjacent strings is within the range of several volts.
