[Sentoa] install inverter charger

[beemersboat at att.net]

Jim,

I've done that install many times - you'll love it! It's not too difficult if you understand AC electricity.
The 120V wires that terminate behind the AC panel should be easy to locate and are labeled.
Your AC panel should already be set up properly, all heavy non-inverted loads should be on the left side of the AC panel. The loads that you want to invert should be on the other two columns.
What you want to do is add a 30amp beaker to the bottom of the left side and label inverter. Hook the black(hot) inverter input to the output side of this breaker. Next, make sure you remove the jumper from the bus bar to the second and third columns of breakers. Note: there may be one on the top and bottom - if you miss one you'll back feed and ruin the inverter if these are not removed. Attach the inverter output(black/hot) to the bus bar on the second row where you removed the jumper wire, this will allow the output AC to power your system (other than left column, which we don't want to invert - the hot water heater, engine block heater, battery charger, etc).
Now you have to hook up the neutral and grounds. They are in the back of the space and are split up according to loads. Same as before, remove the jumper wire between the two and attach inverter wires accordingly. This is important to keep everything separated on the input/output sides of the inverter.
I hope this helps and doesn't add to your confusion. You can call or e-mail me directly if you want.

Good Morning;

I am finishing installing a 2500 Inverter /Charger in Sabbatical a 37 Nordic Tug (2004)  She was prewired from factory in the 120V panel to the mounting board in the engine room.  Though there were no final connections made in the 120V Panel.
 
In looking through the posts on SENTOA I find there is some reference to a Nordic Tug preferred way to make the 120V connections for the Inverter  in and Inverter out lines in the 120V panel.   
 
Though I have written Nordic Tug for their advice they have not answered. 
 
Would any of you that have done this before please  guide  me,  as I tend to over think these problems and drive myself to distraction. 
 
Thank you !
