How big an inverter do you plan to install? For what purpose do you intend
to use it? And how big is your battery bank?

 

I have a 4 battery house bank with 460AH capacity. I have a 1000watt peak
inverter that will deliver about 800 watts continuous and has two 15 amp
plugs on it. I use it to charge cell phones and computers, and the
occasional rechargeable camera battery. The 1000 watt inverter will deliver
up to 8 amps of AC current at 120v. To deliver 8 amps of 120v AC it will
need to draw about 76 amps of current from your batteries when they are at
12.6v, plus about 10% because of the inefficiencies in the inverter. When
your battery charge drops below 12.6 v the current draw will increase. 

 

Let’s assume you draw an average of 90 amps until your batteries are
discharged. Oops, fully discharged ruins the batteries. So let’s say until
your low voltage alarm goes off and you reach 50% on the batteries. On my
boat that is about 230 AH/90 A = about 2 ½ hours.

 

A good 3000 watt inverter will deliver more AC current to run stuff on your
boat like a TV or coffee maker, but it would deplete the batteries at a much
higher rate.

 

So you need to ask yourself the three questions I started with, and pay a
lot of attention to the size of your battery bank.

Subject: Stus-List Inverter to Shore Power

 

Can I connect the outlet of the inverter to the shore power inlet socket
(using an adapter of course)? I don't see why this would be a problem, but
what do I know. Even if I left the converter on it would just waste power, I
think. The advantage, of course, is that all of the AC outlets on the boat
would go live.

Thanks for advice.

Dan
