Note
Check the installation position of the current transformers for the different operating modes of
the Janitza UMG 104 / UMG 604 / UMG 604-PRO.
Note
Check that the phase assignment of the voltage measurements for the current measurements is
correct.
The following output values are recorded in the various operating modes when the installation position is
correct.
Operating mode Output value
► As a Utility Meter (U+I) with positive output value (kW) for feed-in
► As total plant meter with positive output value (kW) for feed-in
► As an inverter with positive output value (kW) for feed-in
► As a consumption or sub-consumer meter: with positive output value (kW) for consumption
► As a consumption meter (bi-directional) When the production is greater than the consumption,
positive output values (kW) (installation position according
to the arrow system)
(From rmware 3.4.2, the counting directions (evaluation)
can be changed in the Solar-Log™ of consumption meters
in bi-directional mode in the device conguration.)
► As a battery meter (bi-directional) ► When the battery storage is being charged, positive
output values (kW).
► When the battery storage is being discharged, negati
