Hunter passage 42 inverter question

[sailor832]

I recently acquired a 1996 hunter passage 42 and was looking at replacing the aftermarket inverter that the boat came with to a Victron 3000 watt inverter charger. The boat has 2 30 amp power cable inputs one for A channel and one for B. When I bought the boat the inverter was powered only from the batteries as it has no pass through while on the 30 amp only supply at the marina I used the switch on the main power panel to parallel A and B together this did run both AC systems without tripping any breakers. But with going to the new Victron unit should I get the Victron II plus 2x 120 and connect each 30 amp input cable separately to each one of the 2 AC in but these would not have a line 2. Which I believe is OK but I am not sure about what would happen when I turn on the parallel switch I could have AC 1 out to the A input and AC out 2 to the B circuit this would only be active when connected to shore power and then A and B would not have to run in parallel. Just wondering if anyone has done anything like this before.

Ok,,,

You need to wire the inverter to the phase which doesn’t power the airco units, or the HW heater. So, combining both shore lines and trying to run from the inverter won’t work
I suggest you look at the factory wiring diagrams, and see how they connected in the original unit. It was most likely a Heart interface (Xantrax) unit, which weren’t the most reliable boxes
Your new inverter / charger will have internal relays which will handle the charger / inverter switchover. As well, it will bond the neutral to ground when in inverter mode

hope this helps

I have the original electrical and it does not show ever having a inverter it does have a 9kw generator.

Ok,
I went onto the documents, and there are no schematics.
You might look on your breaker panels, and see if there is a breaker labelled “inverter”
If not, the place you’ll need to get the output of the inverter wired into is the AC main which is the line which doesn’t power the airco units.
As well, you’ll need to figure out which AC leg powers the water heater. You can’t power the HW heater from the inverter.
Hope this is helpful

That should work if wired properly. Hopefully you have a lockout switch that would prevent paralleling A and B while both are energized. Since the 2x120V automatically parallels L1 and L2 when only L1 is powered, or when inverting, you should never need to use the parallel switch.
