UMG 104, with a 500 MHz DSP (digital signal processor), is a fully fast and powerful network analyzer. The continuous analysis of the 8 channels with 20 kHz per channel allows the recording of the electrical parameters (more than 800 values), minimum and maximum values, the essential voltage quality values as harmonics (up to 40, each phase with the recognition of the address). On the basis of data that production failures can be avoided, concepts can be developed for example to reduce energy costs, the measures taken and with the UMG 104 the achieved improvements can be monitored and documented. Through modern communication architectures the recorded data is sent to a central location, centrally stored in efficient databases and available for further processing in an open architecture. The easy connection of an available building control system or SPS environment extends the areas of use of the UMG 104.

A power meter transmits the measured amount of power to the SolarLog for analysis. It serves as a consumption meter, showing a comparison of produced and consumed power. It can be configured to operate with the SolarLog in three different modes:
- Measuring energy consumption for optimal utilization of the power generated.
- Measuring the total amount of energy that has been fed into the grid.
- Measuring the energy production of inverters that are not directly managed by SolarLog.

Energy Meter single-phase 100 A maximum.
The Energy Meter can be used for these things:
1. grid meter, and used as a control input for an ESS System (1).
2. Measuring the output of a photovoltaic inverter.
3. Measuring the output of an AC generator set.
The meter is connected to the Color Control GX. There are two options for its wiring:
1. direct connection, using the RS485 to USB interface with a 1.8 m long cable, or the 5.0 m long cable.
2. Wireless connection via Zigbee

The Victron EM24 Ethernet is a standard device for measuring the power and energy of a three-phase application, for example in the distribution box or for measuring the output of a PV inverter, an AC generator or an inverter or inverter/charger.

Control center and energy manager via Ethernet, including Energy Meter.

Energy meters are typically used in an energy storage system, to measure the power and energy of the entire application in the distribution box and minimize the import or export of energy to the grid. They can also be used to measure the output of a PV inverter or AC loads and display the data on GX devices such as the Cerbo GX or Ekrano GX and the VRM gateway.
