Victron Energy Meter EM540 - 3 phase - max 65A/phase
Replacing EM24
1. Introduction and usage
This document is the manual for the 3 phase max 65A per phase Energy Meter.
The Energy Meter can be used to:
-
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
When used to measure a PV Inverter, terminals 1, 2 and 3 should face the PV inverter to ensure correct direction of current and power.
Single phase dual function diagram:
In this diagram, a single meter is used to both measure the grid and a single phase PV Inverter
On the CCGX go to the grid meter in the Wired AC sensor settings. Make sure 'Phase type' is set to 'Single phase' and 'PV inverter on phase 2' is enabled.
Wired connection to CCGX
Connect the Energy Meter to the CCGX using the USB to RS485 cable. The RS485 to USB interface cable between the CCGX and the Energy Meter can be extended up to 100 meters; make sure that the extensions of the Data+ (orange) and Data- (yellow) wires form a twisted pair.
| RS485 Converter | Energy meter |
|---|---|
| Yellow (Data-) | Terminal 9 |
| Orange (Data+) | Terminal 8 |
| Black (GND) | Terminal 10 |
The red, green and brown wire coming out of the USB to RS485 cable are not used.

Energy Storage
As more solar and wind power comes on line, it becomes increasingly difficult and expensive, to ensure stability of the grid. Intermediate energy storage is therefore rapidly becoming an essential tool to keep power fluctuations on the grid within manageable limits. Moreover, as feed-in tariffs are decreasing, the business case for a home energy storage system that increases self-consumption becomes more solid every day. Intermediate energy storage increases self-consumption of harvested solar and/or wind power. The natural next step is 100% self-consumption and independence from the grid.
