CROWN II AUTOMATIC MARINE INVERTER CONNECTIONS

[re613]

Hello all, I have a crown II automatic marine converter model R3012F-3, I located a connection diagram on line but looking at the present connections I am not sure if it is the right connection. I have three deep cycle batteries in this older Nautaline houseboat, 73 model I think, currently all three batteries have the + tied together and all the - tied together and the charger has a + line from it to each + on the batteries, the - comes from the charger to all three - at one point. My question is should all the + be tied together or just have the + from the charger to each battery? Also one of the batteries has no load connections on it at all, I think it was just put in line to give the third + a place to go. I know this is confusing but the charger is still good and I want to continue using it to keep the batteries charged.

Are you saying that you have the R3012F-3 converter, and you want to install it on a new to you Nautaline houseboat?

Basically the houseboat did not have this one installed on it and your thinking about changing out what was on it to this one. Is this correct?

Hello, this is a houseboat I bought a year or two ago and the charger was in it, I am in the process of changing the batteries and was wanting to know why the three batteries are tied together with separate wires going to each battery + from the charger when basically the three points from the charger are all going to one point for all batteries.

That helps me some. While not an expert by any means, if the converter is used to charge bats only then I can see the parallel wiring on the bats and the individual wiring on the converter. I to looked up the install manual and it shows all ground together and separate positives going to each bat.

Does the boat have a separate inverter to supply 120VAC, or does this one unit supply the charging and AC supply?

I am going to try and send a picture the broken lines to the positive posts are the jumpers I am concerned about. I cannot seem to download a picture but I have one - from the charger going to all three batteries and have three + from the charger one going to + on each battery but at the same time all + on the three batteries are jumped out making all three + one, does that make any sense ?

This is the 12v supply for everything that needs it, I also have a 5kw onan generator aboard for the 120vac items (AC Fridge TV etc.).

Yes this makes since IF (the big if) the Gen provides all the 120VAC and there is no inverter.

The converter you have is able to charge 3 banks of bats at one time even IF all the bats are in parallel. So there should be no issue with the individual wires coming from the converter to the individual bats, and the bats all being in parallel. The parallel bats provide more power over longer periods for your 12V needs

Thank you, guess why the third battery is there but not connected to any loads, more capacity, I also have two 200 watt solar panels, regulator and power inverter for an extra deep cycle battery for a fan just incase the ac goes out for the wife .

Yep, me all know why we do those things
