Shore Power

[Jfrano]

So it seems to have the shore power Selected and light on; the AC panel i need to engage the AC1 Main Breaker ... will it charge batteries without AC1 selected? Also have battery switch to house for fridge .

AC1 must be on to charge.
DC main and refrigerator switches must be on too cool.

Great. I have a 2017 R29CB, don’t see a dc main or breaker for fridge. Seems it powers up with Bank switch to House. Also the inverter powers up and I can’t turn it off. Am I missing something...Why would I need the inverter converting dc to ac, when I have ac through the shore power?

It all makes more sense if you understand the switch for shore/power/inverter just tells your vessel where the power is coming from. So you pick shore. Then you energize the main panel by turning on ac main. Then you have the option of which breakers you want on. If you select inverter only certain breakers work so you dont quickly drain the batteries. For example grill only works off shore or generator but not inverter.
Inverter should only go on when you turn on inverter switch and then turn source switch to inverter. Is it possible you have never turned off the inverter?? It is a small switch labeled kasai in my case ( R27 2018).

You have me wondering now. Where is the inverter switch. Is it on the inverter or on the panel.

Thanks

I think my switch is Shore/Off/Generator

The inverter Control is via push button, first panel on the left when entering cave.

There seems to be a lot of variations by model and year that where my switch is may not be where yours is...mine is a switch by itself just above breaker panel. Mine is Kasai model and switch is labeled as such. Stays on once you turn it on unless you manually turn it off. I imagine yours is also a standalone switch that came with inverter. Maybe looking online at that model inverter will give you a clue. Perhaps someone with same model can chime in.

I'm not sure if this answers all of your questions, but:

1. There isn't a DC Main Breaker or a Fridge Breaker on our boats. DC loads are supplied directly from the various battery banks via battery selector switches and fuses. The Fridge will remain powered from the House Battery Bank unless the temp control in the Fridge is turned off or the House Battery switch is taken to OFF.

2. While you don't need the Inverter to convert DC to AC while on SP, I recommend leaving it on. You can power it off at the inverter control panel to the left as you enter the cave, but the inverter is also your battery charger. So, when on shore power, with the inverter on, it senses AC input power is available and charges the battery banks through the ACRs. You can find the operator's manual on the Kisae Power website.

I may be wrong and I apologize in advance if I’m confusing anyone, but the inverter does not have to be on in order to charge the battery. While the ProMariner charger/inverter (on my 2016 boat) is a single physical unit, the charger and inverter functions are separate. The small rocker-type control switch for the unit is on the left as you enter the cave and has three positions. Up is for charging while on shore power or generator, middle is to turn the inverter on and down turns it all off. I leave it in the up (charge) position most of the time - indicated by a green led next to it - and select the middle position (inverter on - orange led) when needed. You cannot be charging and inverting at the same time.

This is all separate from the large rotary AC power selector switch on the AC breaker panel, that, as has been pointed out, simply controls the source of the AC power (shore or generator). The AC1 breaker on that AC panel needs to be on with either choice for battery charging to occur, along with the up position selected on the charger/inverter control switch.

mjq1987 is also correct that there is no DC breaker panel (on newer boats - there used to be one on the older ones). Big red House battery switch in the cockpit controls (almost) all DC power to the various DC circuits, each of which is protected by an inline fuse.

I hope this helps and, please, correct any mistakes. Thanks.

Agree. On my set up the inverter does not need to be on to charge batteries. I have probably had it on 5 times in the past year and always turn it off when done. Batteries charged all the time.
