■ Preliminary Confirmations
Check the following items before wiring.
No.
Inspection Item Procedure, Measurement or Confirmation Check
1
Solar module
installation
condition Visual confirmation:
Refer to the technical manual for the solar modules.
2
KP100L
installation
condition Visual confirmation:
Make sure none of the mounting screws are loose.
Make sure that the KP100L and the mounting base plate are securely
fixed with the mounting screws.
3
Wiring,
connection, and
conductivity Visual confirmation:
Inspect for looseness in clamps and screws, proper wire connection, and
conductivity.
4
KP100L ground
resistance Measurement confirmation:
Standard: 100
Ω
max.
KP100L actual measurement:

High voltages exist when the Solar modules are exposed to the sun.
Exposed terminals of the Solar modules are live, and can cause electric
shock. Avoid making physical contact with live parts of the device.
After the Solar modules are connected to KP100L, the input voltage is
greater than 200 VDC, the LCD displays the country setting at first time
operation.
Set a specified country. Refer to “Procedure at the First Time Operation”
for detail.
After the Solar modules are connected to KP100L, the input voltage is
greater than 200 VDC and the AC grid is not connected to the in KP100L,
the Data Logger LCD displays.
5
Connect the
Solar modules
Voltage measurement for each solar module string
Measurement confirmation: DC1 V DC2 V DC3 V
Measure to confirm that the grid voltage is about 230 V.
6
Grid voltage
confirmation
Actual measurement: AC(L1) V AC(L2) V AC(L3) V
Step 1:
Check the connection between KP100L and AC Connection System. And
then check the connection between the Grid and AC Connection unit.
Close the AC breaker or fuse in the unit.
Step 2
Measure the time until operation resumes.
7
Power-ON
delay time for
grid-connected
operation
Step 3
Confirm that the displays the status “Normal” and that the KP100L
performs the grid connect operation.
The KP100L is feeding power to the grid, and the green LED displays.
8
Confirm the
wattmeter The Wattmeter installed to count the injected electricity should work while
the inverter displays that electricity is being injected.
