Marine - AC or DC ?

I have zero knowledge of electrical systems.

My Islander 30 has 2 new batteries, with a 'perko' switch ( rotary switch that can select battery 1, 2, or both for cranking the diesel ).

The electrical panel has 6-8 toggle switches ( cabin lights, nav lights, bilge, ect.. ) it is old and needs replaced.

i would like to buy a panel that has the same 6-8 switches on it, but also has a gauge for each battery's level.

I am looking online, and there are a panels that are AC or DC.
Again - I do not know electricity.

The boat is currently on a powered dock, but will be moved off and I will use a solar panel to keep the batteries charged.

Any ideas or examples of what I want?

Yes, you want to hire someone to do this work for you. If you do not understand what you are doing, you could get hurt and the results dangerous.

That is a good panel but I would go with Blue Seas 8023, 8 position and without the meters. A separate battery monitor like the Victron BMV-600 will tell you more that a voltmeter and ammeter ever could about the state of your batteries. Both are shown below. Prices are from Jamestown Distributors

Anything connected to the batteries is DC.

Don't buy anything until you have consulted an ABYC certified marine electrician. Chances are you will buy inappropriate gear.

Good ideas guys. Thanks.
My old Catalina 25 had 1 battery - only ran nav lights - no bilge, nada.

this Islander has 2 batteries - runs everything - volvo diesel, bilge, macerator?, hot water heater, air, ect.... I better learn the basics of powering them.
