Please take a look at the schematic of this new Leopard Power Cat. It had 2 Pheonix inverters fed by a Centar 100a charger. The owner purchased 2 x multiplus to be able to charge the lithium batteries faster but neglected the fact that the boat did not have a source of 120v besides what was provided by the inverters.
-Shore power is split phase 50a going through an isolation transformer giving 240/60 single phase. Neutral Ground bond at the transformer.
- Selector switch to chose between the IT or generator for source of power.
- Generator wired for single phase 240/60. Neutral ground bond at the generator.
I’ve also included the Victron step down schematic for the autotransformer (disregard hand writing). And if I understand correctly if wired this way the neutral/ground bond would remain through the transformer (since we are not taking a neutral from the center tap?l)
The goal is tapping 120v from a 240 single phase which has N/PE bond at the source. How to best do this and what to do with the N/PE bond at the transformer. I do realize that the max will be 28 amps with this configuration. Considering adding a second transformer to feed each Multi independently. Multi are paralleled.
