Inverter power for Tv and RPT(Remote power tap)

[FireBug1]

I have a 1998 270 with a 4esz Koehler that functions as designed. We have added a 32” smart tv that we watched some great college football on. I have a single 12v 15amp power tap on right side of helm. I ran the generator to provide 120v power for tv and a few fans oh and power for kids IPad. My desire is to have a small inverter to power the above listed items without running Genset for hours.

I am not sure I want a huge one that powers everything because let’s face it the age of the boat gives diminished returns for such a large scale project based upon what I have read. I tried a small 400w plug in but couldn’t get it to turn on @ helm plug in.

So I thought I would turn to this awesome group for advice and maybe some answers. Thank you in advance.

I had a 1200 W one in my boat. Whatever one you get just make sure it`s well filtered for electronic equipment. Also remember the total dc current draw when using the AC . At full draw mine used 100A dc in

Many modern TVs run on 12VDC to begin with. They have power supply bricks that take 120VAC and output 12VDC. If you install one of these TVs, you can just snip off the power brick and wire it directly up to your batteries. This would be far more efficient than running a 12VDC -> inverter -> 120VDC -> 12VDC -> TV

I use a 750w for same purpose. Wires direct to battery terminals behind my electrical panel. Mine came pre installed either by SR or PO and has auto cutout when 120v is introduced to system by genny or shore power. Installed one, also 750w for a friend. Hooked into power in same place, behind power panel and then ran to 2 outlets. Configured the outlets so that top plug was energized by genny or shore power and bottom outlet was energized by inverter.

Just installed a 1000 w pure sine wave inverter in my hanging locker where I had access to the #2 guage wire that feeds my windlas.the .I spliced into the positive wire by stripping 3/4 " of insulation from it and clamping the wire that feeds the inverter to that and reinstating it with liquid rubber and electrical tape. For added insurance added a piece of split 1/2" hose over the splice secured with more tape . The - wire was a simple add a 2 guage wire with a connection point to the down stream side of the windlas breaker. The location if the install will allow for good cooling of the inverter through the bulkhead into the cockpit if I need to . I dock where I have no shore power and run on battery all the time with a 140 watt pv array . Next I will wire to an isolator switch and wire that to shore power feed on my panel
