Kind Of Off Topic Tailgating Advice


Obviously this isn't necessarily work related opening home football game is this weekend and I've done some hasty research on running a TV off a deep cycle marine battery at our tailgate.

I have an optima 75ah deep cycle marine battery and a 400w ampeak inverter. I'm a carpenter not an electrical expert though I'm not incapable of some electrical work. Through reading about it I came to the conclusion that the battery and inverter alone would run an lcd tv that draws 150w max (that's all it says on the back of the TV) for 4.5 -6 hrs? May have that wrong. I grabbed a 100w solar panel and a charge controller to try to draw that out as long as possible. I'm trying to set this all up on a board so I can take it to our camp and use it if we want as well as at tailgates. My only question is the diagram that came with the charge controller recommends multiple circuit breakers to be placed on the 10awg wire in certain points. How necessary are these considering the amount of power I'm drawing and what else do I have wrong in this I don't want a small fire at tailgate saturday. Internet research causes more confusion than answers I think.

Without seeing the diagram, it's impossible to speculate about the necessity for multiple circuit breakers, but it's generally a good idea to follow manufacturer's specs.

Also, if you are using a modified sine wave inverter, it probably won't work with a newer TV. You'll more than likely need a pure sine wave inverter.

You're not running your TV off the solar panel. You're running it off the battery. The solar panels' output doesn't affect the TV.

The panels produce power, which the charger converts and conditions to charge the battery. The inverter draws its power from the battery. You may well be able to watch the game without any panels or charger out in the parking lot.

I will be able to do that for a certain amount of time. We'll be out there fairly longer than a normal tailgate this Saturday so I thought the solar panel I had could possible offset what I'm discharging from the battery enough to.run it a bit longer. This was all just a quiet cheaper solution than buying a quiet gas generator.

I thought he said he had the panel and charge controller to get a little more time out of the battery by charging it while using it.

I am going to give it a test run tomorrow night see how long it runs the tv without the panel. My inverter is modified sine wave but the tv I'm taking is also an over 10yr old lcd tv so I guess I'll have to make sure it works before I go. My issue is what would the circuit breakers be called that wire directly to that 10awg wire? I was looking online but couldn't find a positive answer. Would that be something my local electrical supply would stock?

Re: Kind Of Off Topic Tailgating Advice


Is this on the low voltage side? Between the solar panel and charge controller?

It shows what looks like a low voltage fuse on the positive wire between the solar panel and charge controller. Then shows another lower voltage fuse on the positive wire between the charge controller and the battery. Then I believe it shows a higher amperage breaker on the positive wire from the battery to the inverter. It's not labeled well.

Re: Kind Of Off Topic Tailgating Advice


I think you are confusing Amps and Volts.

All of those fuses would be low voltage (12 Volt).

The fuse from the panel to the charge controller, and the fuse from the charger to the battery, will be relatively low amp fuses.

The fuse from the battery to the inverter will be a much higher amp fuse, depending on the size of your inverter and wire.

It's a pretty standard set-up. I wouldn't delete any of those fuses if I were you.

Re: Kind Of Off Topic Tailgating Advice


My wire will be all 10 guage, the inverter is a 400w continuous, 800w surge inverter. My main reasoning for the post is I was having difficulty determining what fuses to buy. I'd prefer to just go buy them somewhere but I wasn't even sure what this particular type of fuse or breaker is even called. Essentially I was trying to no sound like an ass whem trying to.sesrch for what I need.

Inline fuse for a car amp should work.

Re: Kind Of Off Topic Tailgating Advice


Personally, I'd use a couple of these for the low amp fuses:


Then for the high amp side, I'd go with a 12 volt 70 or 80 amp breaker.

Like this:

Re: Kind Of Off Topic Tailgating Advice


OK I can't get this phukking thing to work.

I used to post images here all the time, now the damn thing is all pukkt up.


Computers piss me off.



Just look for an inline 12 volt fuse holder, I like the ones that take ATC style fuses.

Then look for an 80 amp, 12 volt circuit breaker.

It will probably run for 4 hours. Give it a shot and find out. I did it once while camping but I used the truck to charge the battery a bit.

I've never seen a TV that wouldn't run off a MSW UPS.

Instead of spending the money on a panel and charger, you'd get a whole lot more run time spending that money on a second battery.

I grabbed some fuses today but worked too late to give it a test run thanks for the help the fuses were the main thing confusing me. Those bigger deep cycle marine batteries get expensive fast. Didn't have to buy the solar panel is the only reason I went this way but if it doesn't work I may be getting a second one.

When in the military one of my tasks was to maintain the smallboat batteries. They had large 12v batteries like three truck batteries in parallel. They are big boys, two men to move them but I imagine lots of juice for a long time.
