It accepts both 230V/50hz and 120/60hz shore suppliers and converts it into your Multi Combo inverters. Basically converts what ever it detects to DC

The Victron automatic switching toroidal transformer has been working extremely well for me. It will accept 50 and 60 hz and can be jumpered for 230v or 110v output.
The input can be as follows:
120v up to 32A
208v up to 16A
230v up to 16A
240v up to 16A
It has a temperature controlled fan and is only 24kg.
I have been running one on 120v and 208v in US marinas
(yes, about half of the US marinas
are 208v rather than 240v on the high voltage pedestals)
Highly recommended piece of gear
If you don't mind moving jumpers when changing input voltages then you can save a couple of hundred dollars vs. the automatic switching unit. However, I really like being able to apply any voltage I want from about 90v to 265v. (there is a small gap from about 165v - 180v which I think it will just not connect). If the voltage is out of that range it will not close the contactors. It also provides soft start to keep from blowing the shore power
I have been running that isolation transformer into either a Skylla-I charger
making 100A @ 28v or directly into an 8kva Quattro with the shore power
input limited to 15A. I often draw more than 15A on shore power but the inverter
picks up the slack during the peak by pulling power off the battery
I generally run the system with all shore power going through the charger
and making 230v 50hz power. However, if I need both air conditioners (or more likely both air conditioners in heating
mode) I am consuming about 4000 watts which on 208 is about 20A. In that case the inverter
picks up the remaining load during the peak and then recharges the batteries when they cycle off.
