| + | * The same number of units need to be installed on each phase. An example to clarify: 3 units on L1, 3 on L2, and 3 on L3 is OK. But 2 on L1, 3 on L2 and 3 on L3 is not OK. The only way such non-symmetrical installation is supported is when using no monitoring at all, or a Digital Multi Control. Combining such system with any other monitoring device, such as the VE.Bus Smart Dongle or a GX device like the Cerbo is not supported. Numbers and information shown on the GX device as well as VRM portal will or can be wrong, and controlling the system, for example setting input current limits will not always work properly either. | ||
| + | * While VE.Bus System Configurator allows setting up a system using Multis (each having a single AC input), that is configured to have multiple separate AC inputs, such system is not supported by GX devices. | ||
| + | * This information does __not__ apply to the Multi RS and Inverter RS models, which use a VE.Can interface (not VE.Bus) see the RS product manuals for specific information on programming them for three phase. | ||
