Inverter installation

[Steve36]

Hello everyone, I am planning to install an inverter into a 2005 420 Sundancer. The inverter will be a 2800Watt Pure sine model.
I would like to know if anyone out there has done this installation in a simillar sized boat. I have a buddy coming to help me out. He has done numerous installation of inverters on cars but never on boats. One of the items we are concerned with is how to wire the inverter to the Generator/Shorepower switch. This would let the inverter charge the batteries whether its on shorepower or genny.
Best thing would be a wiring diagram of a typical installation on a boat. Maybe someone out there has one or can fax me one.
Just need to know what I should look out for.
Any help would be appreciated.

Thanks.

We have a 38 Aft cabin and had a 2800 watt pure sine wave put in. It charges at 125 AMPs. We put 10 six volt gulf cart batteries with it. We use the ice maker all the time and it is good for 2 days before the batteries go to fail with no generator input. We run the generator 2 to 3 hours a day. Once every 4 days you will need to run your generator for 4 to 6 hours to fully charge the batteries.
If you use it to make coffee it will suck the batteries down in no time.
We got it installed with a remote. The installer put all the light use items on one leg of the house electric panel. The three AC units, hot water heater, watermaker and stove are not hooked to the inverter at this time. I intend to get this done this winter.
I changed the charge set up so I could charge it off the engine alternators and that seems to help with not having to run the generator all the time.
I do not have a wiring digram of what was done.
When you get the inverter get one that has two legs so you can make both sies of the electric panel hot. Mine has two hot sides and I will get the other side of the panel made hot this winter. A remote is a very good idea.
