25.3.2 Meter connection options for bi-directional recording of the total
consumption via only an RS485 interface.
If there is feed-in in a sub-distribution, the option mentioned above can be used. In this
case, the the amount of feed-in power and power obtained from the grid can be recorded with a bi-directi-
onal meter. With this,
the Solar-Log™ can calculate the consumption.
