Connecting accessories
Note
These meters cannot be used together at the same bus input with inverters that are
connected to RS422 (e.g. Fronius).
Note
Inepro
1250D
All three phases have to be connected for the Solar-Log™ to accurately detect the
meter.
If an Inepro 1250D is used, the PRG button on the meter must be pressed and held
down during entire detection process.
If it is not possible to hold down the PRG button during the whole process, we rec-
ommend provisionally connecting the meter to the Solar-Log™ with a short cable
after the installation in order to be able to press and hold down
the PRG button during entire detection process.
In a second detection attempt with the inverter, the meter is then detected by the
Solar-Log™ even if the PRG button is not pressed.
The detection of an Inepro 1250D in an existing installation can take up to 15 minutes.
After the detection, a restructuring of the data takes places which can take up to 45
minutes depending on the amount of data in the devices.
Note
Inepro
meter
Inepro meters are automatically given the mod bus address 234 by Solar-Log™ dur-
ing the detection process.
This address is therefore not allowed to be used for other devices.
After the configuration the display on the Inepro meters alternates between the me-
ter status and the address display (ID=EA); this is how you know if Solar Log™ has
made the correct detection.
All RS485 meters have to be terminated with an 120 Ohm resistor between the two
pins used.
