Place a cable bridge between pin 3 and 4 on the Solar-Log™.
3.2
Wiring for RS485 meter
The meter‘s RS485 output can be connected to any RS485 interface (A, B and C) on the Solar-Log™.
Overview
•
2-pin wiring.
•
The communication address has to be assigned.
Installation steps
•
Switch off the meter and Solar-Log™.
•
Connect the meter to the Solar-Log™.
3.3
Wiring meters to record self-consumption
There are two options to record self-consumption via the Solar-Log™:
•
Measuring just the consumption.
•
Measuring with bi-directional measurements (two-way measurements) at the grid connection point behind
the utility company meter.
Fundamentally, a separate meter needs to be installed to record energy consumption.
The meters used by utility companies generally cannot be used to send data to the Solar-Log™.
