Energy meter Victron ET112 Carlo Gavacci - REL300100000

The Victron ET112 Carlo Gavacci Victron Energy Meter can be used for four things in combination with Victron inverters:

1. It measures the energy from the mains, connects to the mains input (Iberdrola, Endesa, etc...) for a configuration of ESS system.
2. It measures the output of a PV inverter connected to the system.
3. Measures the output of an AC generator set connected to the system.

To connect the ET112 meter to the Victron Color Control GX display, we can choose one of the following options:

1. Direct connection, either using the RS485 to USB interface with a cable length of 1.8m, or the 5.0m cable (recommended option).
2. Wireless connection via Zigbee.

These configuration options are configured in Victron's own monitoring system. Venus - Color Control - GX Device . Depending on how this setting is configured, it will affect how the information received from the meter is displayed on the COLOR CONTROL screen.

In this example configuration, a single Energy Meter ET112 Carlo Gavacci - Victron is configured as a mains meter and measure the grid import/export of an ESS system with an alternating current photovoltaic inverter (From Fronius for example...). Although the exact output of the PV inverter will not be displayed in its AC AC power, this information is still very useful, as it allows all the PV output to flow first to the loads connected on the same circuit.

With which we will achieve the following;

• The direct solar output of the PV inverter shall be used as the HIGHEST PRIORITY (e.g. Fronius)
• The surplus will be used to charge the batteries (The system will seek to have the surplus that we have programmed; for example, 0W).
• When we have the batteries charged, we will have the option to dump the surplus if we have configured it that way.

This can be very useful to make the most of the solar surpluses if the Victron ESS system is installed as an extension of an existing plant of self-consumption existing.
