Electrical issue

[cwalden]

This is likely my error but on our R23 (2018) I have no power to the main breaker panel under the q berth. I have the house rotary switched on and nothing. Engine fine, thruster fine, but no power to house bank. I ran engine all day on parallel mode hoping to trigger the battery charger in the cockpit port locker, but no read out on the charging unit and as said nothing to the panel. I pushed on the two white charger 1 and 2 buttons but they didn't change position. I made sure red rotary in locker was on, made sure the yellow switch on invertor breaker pushed up into horizontal position and pushed the breaker reset on the furthest aft dial. Can't really see all labels as being large black coiled pipe. Can anybody walk me through the proper positions for each of the items (switched) in the lazarette and why I have nothing to the main panel in the 'shed-q berth. Thanks so much for this.
Dazed and confused!

Are you on shore power? If yes then is the shore power breaker turned on? Can you confirm you’re getting power to the electrical panel? If you turn on the port or starboard outlet switch do you have power to the outlets? And just to clarify you will not have 120 volt power to the panel UNLESS you are connected to shore power.

Thanks. On a mooring, so no shore power. Just looking to be able to supply power from my two house batteries
Thank you!

Do you have an inverter, solar or generator? How do replace the draw from your battery bank?

Hi.
By solar. Found and turned on the house breaker switch in the port locker. House batteries up and operating, but still no lights or activity when the house main rotary is on, eg, port or starboard outlets, water heater, etc. None of the green indicator lights come on. There must be another switch, or a trick to get the battery charger from the engine operating. Everything worked perfectly last season, so I didn't have to troubleshoot then.. thanks for your interest and concern, but still missing part of the solution or problem isolation steps. Have good evening.

If you are not on shore power or a generator your boat is operating on 12 volts DC. The main battery switch in the quarter berth should be turned on which will provide 12 volts DC to your lights, fridge and electronics. Anything that requires more than 12 volts DC will not work.

Do you have an inverter? You can't get 110V while anchored and not on shore power unless you have an inverter or a generator. If you have an inverter it must be on to power the 110 panel.

Hi all,
I must be confusing you kind folks trying to help. The issue is not the invertor or shore power. It is strictly that even though my house battery rotary switch is on in the quarterberth, I am not seeing any power to my main breaker panel..(the small green indicator lights next to switched like battery charger (when engine running), Do the red numerical lights on the main panel come on in battery-on mode or just when using invertor or shore power. I'm wondering if I have a blown fuse for the panel behind the helm? Any thoughts on this and thank you!!!

Did you check to see if your House breaker tripped? It is located in the battery lazarette up near the ACRs.

I will check that, but as of yesterday it was ok. What needs to be on to have main breaker panel showing green lights when switched are flipped. Thanks

Without shore power, you would have to run the inverter to power the AC side of the power system. The inverter only works if your batteries are charged.

On my 2021 R-23, to turn on the inverter, there is a big red switch in the lazerette that should be on. Then there is an inverter rocker switch that turns on the inverter above the solar panel display. You have to press and hold until the inverter beeps. Then, you will have a red light next to the inverter breaker on the panel. Flip that on and then you can turn on your outlets and such. You should not run the battery charger while running the inverter.

The DC side of the system (refrigerator, lights, etc…) is on as long as the house battery switch is on.

The main electrical monitor WILL ONLY light up when you are # 1-connected to 120 volt shore power or # 2- connected to a generator supplying 120 volts. The panel will NOT illuminate when you are on battery or solar power. None of the switches that require 120 volts, i.e. port and starboard outlets, water heater, microwave, stove, that are on the panel will illuminate because you don’t have 120 volts available. If you are not connected to 120 volt shore power or a 120 volt generator you will not have 120 volts available. Solar power will give you some wattage but not enough to give you 120 volts.

I would add “running the inverter” to your list with the caveat: 12V battery power required.

There may be a switch between the inverter and house batteries. This has to be on in order to get power to your inverter.
