inverter install

I have a 2004 Southwind 32v without an inverter. I have an estimate of right at $3000 to install a 2000 watt with all the appropriate wiring switches ect. All I want to be able to run is the front and back TV plus I have a surround sound system with a 6 disk changer.

In addition I was told I should add two more 6 volt batteries which would be an additional expense of the installation plus batteries. I was also told I would need 4 new batteries because they all need to be the same type and age.

Any ideas or does this sound like something I should go ahead and do?

Ron, I would recommend you slow down and do some more research right here on iRV2.com. First you do not need a 2000 watt inverter for your intended purpose and second the cost of installing a 1000 watt should be about 1/3 and you may be able to use the present battery bank.

RV Wizard is right. We have a 1000 watt inverter and two 6-volt batteries and did just fine running TVs, a satellite receiver and a computer. This type of setup will work fine even for extended boondocking provided you can run the generator once or twice a day to recharge the batteries.

My '06 Itasa is available with a 600 watt inverter. It has 2- 12 volt batteries to power the same type of equipment you have. I agree with the others-- at most all you need is a 1000 watt inverter. I would seek out another dealer who understands your needs.

I have same. Setup with a $60 inverter. Blew the first 1200w unit due to running inverter while runing generator, improper wiring . Plus I run my printer. Also run a 1200 watt generator. Less then $400 total cost.

Ronnii: It's simple to figure out what size inverter you need. Just look for the wattage rating on the nameplates on the TVs and surround system. Add them up and you will have your figure. Go about 25% LARGER to let the inverter run easy. Example 100 watts for the surround, 150 for smaller TV, 200 for larger TV = 450 watts total. A 600 watt inverter would be great.

If you have old style CRT TVs, you can replace them with LED backlit LCD flatscreens that will use much less electricity. That will let you you use a smaller inverter and battery bank.

One thing if you do decide to add those other 2 batteries then yes you would need to buy 4 at once since yes they should be the same type and age.
But if you are only going to do a 600-1000 watt one then you should not need to upgrade to 4 batteries.

We did an install on a southwind, but different.

Picked up a harbor freight 750 watt inverter and had a couple indoor rated 70 amp hour VRLA batteries along with a Battery minder.

TV converted to panel that is 12 volt

Inverter powers dvd and tv when dvd is needed, otherwise tv operates on 12 volts

Built ATS for both the 12 TV power and inverter output, simple relays
