How to run the TV on Battery?

If we want to watch a DVD while driving and the outlet under the table to work too for a computer or phone, what exactly would that entail and cost?

I know I need an inverter and to add x batteries, but that's all I really know about it. Let's say I want 6 hours of power for these additional devices.

Is it possible? And what am I looking at in terms of cost to have that done or set it up myself?

Just some general guidance is all I'm looking for here.

Thanks to all.

You can always start your generator. Really surprized the FR3 didn't come with an inverter.

OR--------you can replace your current TV with a 12v LED HD unit. NOW you can simply run it off the 12v outlet in your RV. No extra wiring, inverters, etc, etc!

PS- your phone will charge from a 12v cord using the "auto" cord plugged into any 12v outlet in the RV. Your computer should have adequate battery to last on a daily basis while traveling down the road, simply charge it on 120v each evening/night!

Seriously, since the motor will be running, a 400-1000 watt inverter wired to your existing house batteries would be charged by your MH going down the road.

Use as SHORT a run (at a gauge suitable for the inverter at max draw) as possible from the batteries; fuse according to the inverter wattage and run an extension cord to where you want to use the power.

For a 400 watt inverter, the max current at full load is 34 amps. For a run from the batteries to the inverter less than 6 feet you can use 8 gauge wire and fuse at 30 amps. At 10 feet you will need 6 gauge wire, etc.

For a 1000 watt inverter, the max current is 84 amps. For a run from the batteries to the inverter of 6 feet or less, you will need 4 gauge wire (typical battery cable) and fuse at 80 amps. Much beyond 10 feet you will need all wires including the batteries to be upgraded to 2 Gauge.

Did that help?
