- | For a three phase utility connection, use a three phase meter. For a three phase PV Inverter, use a three phase meter as well. For a single phase utility connection, use a single phase meter. And in an installation with a single phase utility connection, that also has a PV Inverter that needs measuring with a Victron meter, then you can use Rutger | + | For a three phase utility connection, use a three phase meter. For a three phase PV Inverter, use a three phase meter as well. For a single phase utility connection, use a single phase meter. And in an installation with a single phase utility connection, that also has a PV Inverter that needs measuring with a Victron meter, then you can use 2 pieces of ET112; or use the ET340. |

+ | The Ethernet model will have an advantage in installations where an Ethernet network is available. Rather than having to pull an RS485 wire between the main AC distribution board and the storage system, the existing Ethernet can be used. | ||
+ | |||
+ | The disadvantage is that this relies on that network functioning properly - in case of issues the Storage system will switch to idle mode: passthrough. | ||
