Multi RS19 Solar

System configuration: Select either standalone or a three phase configuration.

Phase selection: Choose which phase this current Multi RS19 Solar will be connected to. Each Multi RS19 Solar must be set to a different phase since only one can be allocated per phase.

System instance: Multi RS19 Solar units with the same instance number will work together as a group on the AC side.

If you change the System instance then you can have multiple groups of Multi RS19 Solar units on the same physical VE.Can bus operating independently. Different groups will not synchronize with each other.

Prevent CAN network islanding: Enables the CAN network islanding detection. The default setting is enabled.

Total number of inverters: This option will not be available if the above option "Prevent CAN network islanding" is not enabled.

Specify the total number of inverters that make up the System. In a standalone System, this will be 1.

If the CAN network is split into segments, this setting is used to determine the largest and shut down the smaller segment to prevent them from continuing on their own unsynchronised.

This results in a more reliable System compared to the smaller segment trying to continue on its own unsynchronised (which will lead to overload or other less graceful shutdown issues caused by an unsynchronised AC output sine wave).

Inverters per phase to start: This is the minimum number of inverters which must be present per phase when starting the System. Given that there can only be one Multi RS19 Solar per phase, this should be set to 1.

System configuration: Select either standalone or a three phase configuration.

Phase selection: Choose which phase this current Multi RS19 Solar will be connected to. Each Multi RS19 Solar must be set to a different phase since only one can be allocated per phase.

System instance: Multi RS19 Solar units with the same instance number will work together as a group on the AC side.

If you change the System instance then you can have multiple groups of Multi RS19 Solar units on the same physical VE.Can bus operating independently. Different groups will not synchronise with each other.

System settings sync: This option allows the synchronisation of certain settings across multiple Multi RS19 Solar units in a group. This helps to ease system configuration and to ensure consistent settings between members of the group.

See more details in the next section.

Prevent CAN network islanding: Enables the CAN network islanding detection. The default setting is enabled.

Total number of inverters: Specify the total number of inverters that make up the System. In a three phase System with one inverter per phase, this will be 3.

If the CAN network is split into segments, this setting is used to determine the largest and shut down the smaller segment to prevent them from continuing on their own unsynchronised.

This results in a more reliable System compared to the smaller segment trying to continue on its own unsynchronised (which will lead to overload or other less graceful shutdown issues caused by an unsynchronised AC output sine wave).

Inverters per phase to start: This is the minimum number of inverters which must be present per phase when starting the System. Given that there can only be one Multi RS19 Solar per phase, this should be set to 1.

Continue with missing phase: This is disabled by default. If enabled, then it would be possible for two other Multi RS19 Solar units to continue providing power to their respective phase.

Switch phases as a group: Disabling this option will allow the System to continue working even if one or two phases from the AC input are missing. The System will continue to produce three phase output from the AC-Out terminals.

This can also be used if a three phase output is required, but there is only one phase available from the grid or generator.

You can choose to disable sync if you don't want to use it.

If this is the first Multi RS19 Solar to be configured in this System, then you would likely choose to use the settings on this Multi RS19 Solar for the rest of the system.

If this Multi RS19 Solar is a new member of the group, or is a new Multi RS19 Solar replacing a faulty one, then you can take the settings for this Multi RS19 Solar from the group.
