Questions on the 25SC battery bank charging and Inverters

[The Kraken]

We own an RC25 with a generator?

We have some questions - what battery banks get charged when you are underway with main engine running?

What is any battery banks get charged when the Generator is Running?

Next topic -

We installed a Kisae SWXFR1230 - and it does not seem to be passing AC through when plugged into shore power. It appears to drain the house batteries, fault out and then my battery charger which is plugged into the AC output of the inverter stops and thus no charging happens at all.

We have tried Setting PSO PS1 and PS4 - any ideas?

What year is your 25SC? I have a 2012 25SC and understand the way it charges but that may not be how any other year works.

They should all be charging eventually when the charge relays kick in. I can't be sure on the generator, but I am pretty sure same will hold true with that if you are powering up the charger via the generator.

You should not have your battery charger on the inverter circuit or any high power usage items for that matter. Perhaps your automatic transfer switch is defective or perhaps your shore power is not really providing power and your settings are such that without power the inverter kicks in automatically, hence when you are using power you are using the inverter and draining the batteries.

When on shore power can't you if the inverter is working properly - it should pass the power through and then charge the batteries.. that is what I am confused about..

All batteries should be charging when the engine is running, as Knotflying says the combiner relays will parallel everything together if the parameters are met.

I have never heard of a battery charger being connected to the AC output side of an inverter, it doesn't make any sense at all. I suggest you have a local marine electrician look at your system and help you out with this.

I will assume by the year that you have the Promariner Combi. The remote switch has three positions. Middle is off. Up will activate charger when on shore power and transfer switch will kick in. If you are anchored out and the switch is in the up position your charger will not work and you are in standby mode. with all 110v items off, If you look at your 110v panel you will see your voltage needle pulsating. The Combi is searching for a load. If one exists longer than a specific time the inverter activates and powers up 110v using your batteries. If the Switch is in the down position you do not have the charger activated and the inverter is providing 110 power via the batteries. Also, based on the age of your boat I suspect that the heavy load items are not split in the panel from inverter supplied 110V and Shore power 110V. This requires being careful and not having your hot water heater on, stove if electric or air conditioner while anchored or not on shore power. If they are on you will overload the inverter and it will go into fault mode and/or deplete your batteries. Using your generator is a whole different lesson. :lol:
