Electrical panel

[jmauld]

I have four batteries. Two houses batteries and a battery for each engine. Should I need to turn on the engine battery solenoids to get power to the DC side of the electrical panel?

usually no,house is from the house circuit. Why not tell us what the problem is

That is what I think the problem is. I don’t get power on the DC circuits until I switch on the port battery. I shouldn’t need to leave that on at the dock, right?

Then what is running on the “house” battery when it is the only one on?

I run three banks but I had to customize my main circuit panel feeds to accomplish that OEM is usually NOT setup for a dedicated house bank.

On the 44 I had two banks of batteries one port and one starboard. The Starboard batteries ran the house and cockpit DC side and the Port ran the bridge. At the dock I left the Starboard on always and just turned off the port/bridge unless I was up there.

Okay, so I was mistaken about my battery configuration. I just trusted what I was told and didn’t really check for myself. (Sorry, new owner goofs).

The batteries are setup with two batteries attached to each engine. One set of batteries run the cockpit accessories, and the other set runs the cabin accessories.

Which is what Carpediem posted. Which explains why my surveyor suggested that I install a fifth battery just for the generator. Is this common and should I add this to my list of things to do? It does look my charger can handle a 3rd battery bank.

A dedicated generator battery is common, it gives you an isolated battery that should be able to start the generator even if the other banks are to weak to start the mains. Once the generator is running now you have the AC charger available to bring up the other banks.
