Connecting the inverters
Albatech APL Triphase 15 / 20
Solar-Log
1000/500/200
Installation 113 of 268
4. If your have made the cable yourself, connect the wires as shown in
the following diagram:
Solar-Log™ terminal block connector
5. Connect data cable to RS485+, RS485- and earth terminals.
6. If only one inverter is to be connected this must be terminated.
7. To terminate set the jumper at J1 to pins 9 and 10.
8. Screw the inverter cover on again.
9. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connecting inverters to each other
(Solar-Log
500
, Solar-Log
1000
)
The wiring is done using the
self-made, shielded 3 wire data cable.
Where to connect: Terminal strip inside the inverter
Procedure
1. Switch off the inverters and the SolarLog™; ( Page 17)
2. Unscrew the side cover as shown in the inverter's instructions.
3. Connect data cable to RS485+, RS485- and earth terminals.
4. Connect the other inverters to each other in the same way.
5. Terminate on the first and last inverters.
6. Set the jumper at J1 to pins 9 and 10.
7. Screw the inverter cover on again.
8. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Allocating communication addresses
Before the inverters can be detected addresses must be allocated to them.
To do this you must connect to the unit either via the Ethernet or RS232.
You will find details on this procedure in the inverter's handbook. Now set an-
other address (1 - 247) from the modbus parameters for each inverter and
leave the baud rate at 19200 bit/s.
Note:
When selecting inverters “APL triphase” must be selected.
