I am looking at specifying a 7000w isolation transformer onto a yacht destined for the US. The shore line available is 230v split phase 50 amp at 60Hz. This obviously consists of two lines of 115v. The transformer is rated at 230v. It is my understanding that L1 would connect to the L in on the transformer and L2 would connect to N in on the transformer. Has anyone got any experience of a setup like this. Also would it operate if there was only 1 line of 115v available (with a rewiring of the neutral link)? The output of the isolation transformer will be coupled into a pair of 24/5000 120v quattros.
Victron does not make a split phase iso transformer.
so you can not use it the way you listed.
If 3600 watts of shore power will work then you could use the victron 3600 watt auto 120/240 transformer
In this setup the 3600 watt auto transformer would only connect to one of the inverters, and either a 120v or 240v shore power connection would supply 120v to that inverter only.
You can still produce split phase on the boat, just a bit less efficient.
You will need to disable switch as a group in the setup on inverter.
if you need 7000 watts split phase and auto adjustment on the input consult with a professional for help with this using non victron transformer.
