Solar-Log™ PRO2 (RS485 oder S
0
) connection assignments
The meter connections are labeled IN (bottom) and OUT (bottom).
As consumption or sub-consumption meter: Connection to the grid (IN) – connection for appliances (OUT)
As inverter /production meter: Connection for the production (IN) – connection to the grid (OUT)
Solar-Log™ PRO2 connection assignments (only RS485)
As battery meter (bi-directional): IN = connection to the grid – OUT = connection to the battery
Please note that only Solar-Log™ PRO2-Mod meters can operate on the RS485 interface (one or several). It
is not possible to combine the operation with other components.
If the meter is the last device on the bus, it has to be terminated at connection block10 and 11 with a
resistor (120 ohm / 0.25W).
All display values of the meter
Change the meter from the automatically rotating display to the manual display by pressing the keys.
Pressing on the keys here allows all of the available display values to be accessed in sequence. Please refer
to the attached table for the menu navigation. If no keys are pressed after a short time, the meter reverts
back to the automatic display mode.
