Addding inverter to 2004 Southwind 32v

My buddy has the above mentioned MH with the old analog TV and Direct TV and wants to be able to watch it without running the generator. When he bought it a year or so back, the dealer offered to put in an inverter for $3,500. He wants me to ask
how difficult would it be to install a small 400w inverter next to the front TV taping off the 12v wiring above the passenger seat.
Not sure if the analog TV and Direct TV receiver would exceed the 400w or maybe 800w. Also, could the inverter or a larger wattage one be somehow connected to the existo transfer switch?

    Just like online News sites, that have perfectly easy to read articles, but in addition, talking heads that try desperately to shout exactly the same words in your ear. Sort of like barn guiding a hog with a wash tub and baseball bat.

    I could no more sit before an imager for hours on end than remain in camp watching trout rise on a mirror like like. It's only after one has been removed from it's hypnotic allure for a few months that things come into perspective. Or go to a kiosk in a car agency and have a used car info ad spit out of a slot rather than have a slick hair 38 toothed crocodile emerge from his office in a fluorescent Paisley suit.

    To each his own.

    My NOOK and Kindle consume energy as does this laptop so I am equally guilty there.

    Back on point. A PSW device avoids game playing (Shake The Jar Dewey And See If They Fight) trial and smoke that one must engage in with modified sine wave. Like the LED projection clock that went insane on MSW or my Respironics BiPap that displayed Martian on it's LCD screen.
  • What is this word "television"? My RV is a tv free zone!

    Victron sells a 350 watt PSW for less than $100 usd.

    You can buy a 1000 watt MSW inverter for less than $100 and mount it next to his batteries and run the whole house with it with an extension cord running back to his genset plug or transfer switch which ever he has. If he has 2 6V GC batteries it would be fine to run his TV from it. I would not pay $3500 to watch just a TV.
  • The inverter needs to be as close to the battery bank, as humanly possible, without being in the same compartment. i.e. 2 or 3 feet.

    Even a 350 watt inverter may present a load of 35 amps to the bank. The farther it is from the battery bank, the thicker the wire needs to be.

    He has no place for the inverter/transfer switch in or near the power panel in the bedroom. He's hoping we can just tap into one of the heavy 12 or 14 gauge 12v wires in the above the driver's and passenger cabinets. Looks easy enough except for that TV plug.
    Any more suggestions?

  • My buddy is happy with the old analog TV and old Direct TV receiver. I looked at the power cord for the Front TV and it looks like some sort of special priority plug. I can't seem to remove it from the receptacle Anyone know what I'm talking about? He has no place for the inverter/transfer switch in or near the power panel in the bedroom. He's hoping we can just tap into one of the heavy 12 or 14 gauge 12v wires in the above the driver's and passenger cabinets. Looks easy enough except for that TV plug. Can't take a picture as I am at home now. But will be camping again with him shortly.

  • Victron makes a 350 watt pure sine wave inverter. It is often a bargain selling for about $80 usd. It is intended to be hard wired to the battery bank.
  • NO the 12v lighting circuit is not heavy enough wiring and TOO LONG of wire, too far from the batteries
    just when you get interested in the movie or 'sports' broadcast
    the voltage drop will cause the inverter to alarm or maybe shut down

    a 300w continuous inverter is big enough
    mount near the batteries, but NOT in the same compartment
    run the 120v line from the inverter to the TV area
  • Transfer switch is easy.

    1a) disconnect 12v and 120v power source.

    1) Plug this into the inverter:

    2) remove branch circuit romex from the 120v panel and connect to the transfer switch output terminals. (all 3; hot, neutral, ground)

    3) Short piece of new romex to connect the breaker panel to the switch input terminals. (again all 3; hot, neutral and ground)

    4) restore power and watch some tv.
  • Time2roll, where in SoCal are you? We are in SFV and Santa Paula. Out at Rincon right now.
  • I recommend a 300 watt mounted next to or behind the 120v-12v distribution panel. Pull 12v from the main feed to the battery. Use a small $50 transfer switch in the branch circuit that connects to the tv. If 300w is too small... get a new led flat screen tv already. $3,500 is crazy talk to run a tv.
