I am building a new home and I will be installing a 3-phase (230V/400V) using Victron Gerbo GX, 3 x MultiPlus-II, 12kWh solar array (with MPPT chargers) and a ~40kW (48V) battery, but I also need a little less than 2kVA at 120V, this is just to power my audio hifi equipment, for this I am planning to add an Autotransformer... but I was wondering, would it be possible to add another MultiPlus-II 2x 120V (US version) just to power my hifi equipment? This would provide me a standard 120V @ 60Hz instead of 120V @ 50Hz from the Autotransformer but this inverter will be connected only to the lynx 48V busbar.
