Carlo Gavazzi EM24DINAV53DISX (see FAQ Q7 [11]) The EM24 meter counts energy in a different way than the ET340. For Germany and most other countries; the EM24 is the advised model. See FAQ Q4 and Q8 [11] for further details regarding energy counting differences. - Page 5 ET111 Compatible with ET112 EM112 Compatible with ET112 EM340 Does not report exported energy per phase (unlike the ET340) EM21 72D Does not report exported energy / com protocol not compatible with supported grid meters EM271 Does not report exported energy / com protocol not compatible with supported...

On the GX device 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. 3.1.2. System examples Example diagram In this diagram, a single ET340 is used to both measure the grid and a single phase PV Inverter. Page 4 Installation and configuration... -

Zigbee to USB converter & Zigbee to RS485. The Zigbee to USB converter is connected to the GX device and the Zigbee to RS485 converter is connected to the ET340. Step 1. Connect the Zigbee to USB converter to the GX device using the supplied USB cable. A few seconds after connecting, the active LED should be on and the TX/RX LED should be blinking (the converter takes its power from the GX device, so the GX device needs to be switched on as well). -

Page 11: Multiple Energy Meters In One System
Connecting multiple meters to the same RS485 to USB interface cable is not possible. Connecting multiple ET340 meters to the same RS485 to USB cable is not possible: the ET340 meter has no display and its modbus address can therefore not be changed. -
Page 12: Information On Multiple Zigbee Pairs
Energy Meter Manual 4. Information on multiple Zigbee pairs 4.1. Multiple Zigbee pairs Running multiple Zigbee pairs is rather unusual and not recommended due to its complexity in configuration via the Chinese language configuration software. However, for those who still want to try, we show a possible solution. The following is only valid for the new Zigbee converters with part number DRF2658 and DRF2659. -

These meters have a different way of calculating the total of energy imported and exported. In the ET340, the energy imported and exported is counted at each individual phase and then the Total is provided from the sum of those values. - Page 14 Electronics. • USB485-STIXL : Isolated USB to RS485 converter Q10: Can I use Victron Energy Meters instead of a Victron Inverter/Charger to make use of a GX device (e.g. Cerbo GX), VRM and other features? Energy Meters are intended to supplement a Victron Inverter/Charger in the system. Energy Meters are currently limited in their potential applications.
