Freedom 10 Inverter Installation

I installed the Freedom 10 basically for the battery charger at the dock. Since then we have gone on two trips, one for three days and one for five days. We love our coffee and have tried many ways of making it. Now with the inverter we are back to the old style 110v brewed coffee. We figured that the first pot cost $700 to brew and by now our 8th pot we have broken the $100 per pot mark. Maybe by next summer we can be down to the same as Dunkin Donuts $1.18 per cup. Where did I put it...I searched but to no avail for space, it had to go under the chart table. I chose the hull side wall because I wanted to be able to see the top and still have room for my legs. I held the heavy inverter on a cushion on the floor under the chart table, slid it to the port hull wall, one inch away from the holding tank wall. (This hull wall is on an angle). Slide the inverter up the flat part of this angle wall till the inverter top hits the vertical part of the hull wall. Mark the mounting holes. Drill the mounting holes (watch out you do NOT drill thru the hull, there is a 1/2 inch void back there). Start the top two holding screws so you can hang the inverter on them and be able to remove for wiring. I purchased two 6 foot #8 110v cords for the rear and wired it to the inverter. Don't forget the ground wire and the plug for your monotor. They all go in the rear of the inverter. With all wires hanging from the inverter I mounted it to the wall with four ss screws and washers. I then bent all wires 90 degrees and drilled four 3/4 inch holes into the holding tank wall, keeping everything as close to the inverter as possible. From the holding tank area it was easy to snake the 110v wires to the fuse panel. The two battery cables I snaked under the floor and up next to the water heater. They would not reach the battery, which was ok, because, on the water heater wall that backs up to the battery box I mounted a 200 amp fuse and a new cable to the battery from there. The black ground wire had to be extended by purchasing a connection post to continue on with a new piece of cable. As for the cable, I am not a purest so I went to my local auto store and bought #2 welding cable (bends much easier). All my battery cables will, as I get time, be replaced with this #2 cable. Check the price locally, if you need 60 feet, it adds up. I bought copper ends, pretended that I was a plumber and soldered them on all the wires, hammered them somewhat flat to check the solder and made a heavy imprint with a nail set (actually I used a Philips screw driver end). I wanted to make sure that they all were tight. Finish up with red and black shrink tubing to color code. I did run into a problem with the 110v line from the dock side plug entrance. It seems that on my boat they ran all the green and white wires to a terminal block and only the black to the on/off switch. The inverter calls for the incoming line to go directly to it. YOU MUST TRACE THIS LINE AND DISCONNECT IT FROM THE TERMINAL BLOCKS. It must go to the inverter and then return from inverter to terminal and switch. It would not be a bad idea to run a non spliced wire from the inverter to the dock side plug socket...figure about 18 feet of wire. This will be a rainy day future project for me. For now I bought a plastic junction box with cover and made this connection. As installed I can lean over the chart table cushion and see the top of the inverter with its fuses and switch. It may seem that it is noticeable but it is NOT. I still get a thrill showing people that at anchor I can light the 110v table lamp. Hey this is a new concept for us...along with the engine heated hot water...never had these items before. Al and Michele #55 "Kindred Spirit"
