 Make sure all settings are the same and update firmware on all chargers to the latest version.
+This error also appears if MPPTs are connected to a GX device while configured for a VE.Smart network. Disable the VE.Smart networking features and use DVCC on the GX instead.

 The inverters remain operational, they won't connect to the grid. Once the issue is resolved the units will connect.
-==== Err 74 - Phase overload ====
+==== Err 74 - Too many units in parallel ====
 Applies to Inverter RS and Multi RS models. Firmware versions 1.12 and higher.
 The number of inverters in parallel doesn't match with the transfer capabilities of the ac input relay of the Multi RS or Transfer switch.
-Firmware v1.12 does not support parallel units and a grid connection, so any combination of a Multi RS with a grid connection with more than one unit in parallel will trigger this error code on the Multi RS. The Multi RS only supports 3 units in 3-phase configuration at the moment.

+==== Err 75 - Network misconfigured ====
+Applies to Multi RS models. Firmware versions 1.19 and higher.
+Three phase operation is not yet certified in combination with the selected grid code.
+The inverters remain operational, they won't connect to the grid.
+==== Err 76 - Network incomplete ====
+Applies to Inverter RS and Multi RS models.
+The inverters shut down because there are insufficient units to operate a networked setup. Check if all required units are powered on and that the CAN interface cables are connected properly.
+All units remain off until the installation is fixed, after which the units resume operation.
+Related configuration settings in VictronConnect are "Prevent CAN network islanding" + "Number of inverters in the system" and "Continue with missing phase" in the System section.
