Connecting accessories

Note

The measurement voltage must in effect be at least 10V or an exact measurement is not

possible.

Connect the Utility Meter to the RS485 bus of the Solar-Log™ according to the following diagram:

The RS485 bus must be terminated.
Install a 120 Ohm, 1/4W resistor between Pin 22 and 23 of the Utility Meter to terminate.

Configuring the Utility Meter from the display

Setting MODBUS Address (PRG 200 = 1)

Setting Baud rate RS485 (PRG 202 = 2)

Setting Mode (PRG 203 = 0)

Setting Current converter primary (PRG 000)

Setting Current converter secondary (PRG 001)

Setting Voltage converter primary (PRG 002)

Setting Voltage converter secondary (PRG 003)

Refer to the accompanying manual of device for the UMG 104 configuration procedure.

Note

The parameter settings need to be adjusted before the device detection.

If the parameters differ, the Utility Meter will not be detected by the Solar-Log™.

Perform an inverter detection
See the installation manual, Chapter "Performing inverter detections."

Check

Does the Utility Meter display a positive value for inverters feeding power?
If this is not the case, the current and voltage measurements are incorrectly connected.
If necessary, switch the polarity of measuring inputs.
