The Victron EM540 is a standard device for monitoring power and energy parameters in 3-phase applications, such as in distribution boards or for monitoring the output of PV inverters, AC generators, or the output of an inverter/charger.

Information from it is acquired and displayed on GX devices and the VRM portal.

• Compact design
• Better access to RS-485 connectors for easier installation
• For 3 phases, max. 65 A
• Direct connection via RS-485 interface to USB interface
• Built-in LCD display

The EM540 can be configured in a GX device (e.g., Cerbo GX) for four different roles:

• As a grid meter and as an input control element for an ESS (Energy Storage System)
• For measuring the output of a PV inverter
• For measuring the output of an AC generator
• As an AC current meter for measuring the output of an inverter or a charger/inverter
