Victron Energy Meter ET112 Single phase AC loads/inputs for Color control GX
The ET112 (for single phase max. 100A) Energy Meters are typically used in an Energy Storage System.
To measure the power and energy of the whole application at the distribution box. Or to measure the output of a PV Inverter, to display the data on the Color Control GX and the VRM Portal.
Introduction And Usage
This document is the manual for the single phase max 100 A Energy Meter.
The Energy Meter can be used for four things:
-
Grid meter, and used as control input for an ESS System(1).
-
Measure the output of a PV Inverter
-
Measure the output of a AC Genset
The meter is connected to the Color Control GX. There are two options in its wiring:
-
Direct connection, either using the RS485 to USB interface with 1.8m cable length, or the 5.0m cable.
-
Wireless connection via Zigbee
Victron part number REL300100000 is the ET112-DIN.AV01.X.S1.X from Carlo Gavazzi. And that is the model we keep in stock.
Other ET112 models from Carlo Gavazzi can also be used, as the communication is the same.
Grid Meter - Wiring when used as a grid meter. PV Inverter - Wiring when used to measure PV inverter or AC Genset.
This configuration option of either Grid Meter, or PV Inverter is set in the Venus-device. That selection will effect how the system should be wired, and how the information received from the meter is displayed on the screen.
In this example configuration, a single ET112 is configured as a Grid Meter and will measure the grid import/export of an ESS system with a AC PV inverter. While the exact production of the AC PV inverter will not be seen, this is still a useful configuration as it allows the AC PV production to first flow to the non-essential loads on that same circuit.
-
A surplus will be used to charge the batteries (seen as export and tried to reduce to grid set point eg 0).
-
A deficiency will trigger a discharge of the batteries (seen as import, and tried to reduce to grid set point).
