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-directional
meter. With this,
the Solar-Log™ can calculate the consumption.

Important information on possible options when using meters for recording consumption:
•
Bi-directional meters (only via RS485) in the operating mode „Consumption meter (bi-directional):“ It is only
possible to have one meter per Solar-Log™ device. Additional meters are only possible as „sub-consumption
meters.“
•
Uni-directional meters (RS485 or S0) in the operating mode „Consumption meter:“
It is possible to have several meters connected to a single Solar-Log™ device as consumption meters – the
consumption value is totaled together. Additional meters are also possible in the „Consumption meter“ opera-
ting mode.
•
Meters in the „Consumption meter“ operating mode are used to display the consumption values from indivi-
dual appliances. These consumption values have already been recorded in the total consumption values by
the uni- and bi-directional meters.
