Energy Meter EM540 - 3 phase - max 65A/phase

The Carlo Gavazzi 3-phase meter EM24 RS485 has been replaced by the new model EM540 RS485. Advantages of the EM540 compared to the older EM24:

Faster measurements, making the ESS more responsive
Smaller footprint
Better access to RS485 connectors for easy installation.

The EM540 only communicates via RS485 and can therefore be used with our RS485 to USB cables:

ASS030572018 RS485 to USB interface 1.8m
ASS030572050 RS485 to USB interface 5m

Features:
The Victron EM540 is a standard device for power and energy measurement of 3-phase applications, for example in a switchboard, or for measuring PV inverter, AC generator or inverter/charger power. Its data is displayed on the GX device and the VRM portal.

The meter can be configured for four different roles in the GX device (e.g. Cerbo GX ):

As a network meter and used as a control input for the ESS:

To measure the output of a PV inverter.
To measure the output of an AC Genset.
As an AC meter to measure the output of an inverter or inverter/charger.

The meters have a different way of calculating the total energy drawn and delivered:

For the ETXXX series, the physical energy drawn and delivered by each phase works separately (by phase) or alternatively summed according to the settings in the GX device. In the VRM portal in the energy balances, the measurement is then adequately displayed by phase or summed.

For the VM-3P75CT, EM24, EM3XX, EM5XX series, the physical energy consumed and delivered by each phase works separately (by phase) or alternatively summed according to the settings in the GX device. However, in the VRM portal in the energy balances, only the summation is displayed whether the GX settings specify phase-by-phase or summation.
