It's pricey in the short term, but Lithium batteries will give you more juice. Add solar, say, 500 watts, perhaps even a portable panel, and you should be good to go... if not, genny will help fill in the shortage

Thanks all! So if I was to get a 500w inverter, where would that be installed in a travel trailer? Is it installed behind the breaker/fuse panel? Per recommendations,I will search google and youtube for inverter installation. I'd be fine adding it just to our primary TV location as that is also where we recharge laptops and phones in our camper, but just trying to wrap my head around the wiring and mounting location of the inverter itself. Thanks again!

If you can route the wiring, you could use one of these.That would give you a dedicated outlet. To make things easier, I added a couple relays to switch between shore power and inverter power at that outlet. That way we don't have to unplug from one outlet and plug in to the other when we want to watch tv.

As far as where to place the inverter, it will depend on your rig. I placed my current one behind my fuse/breaker box since 12 volts was easily accessible there. When I change to the larger inverter, I will mount it next to the batteries so I will have a very short run for 12 volts. My 5er came with a generator prep so I can tie 120 volts in to that. That powers an outlet that my 30 amp cord will plug in to, so no further switching will be required.

I am still debating reusing the relays to turn off the converter, or just using a light switch to shut it off.

Install the inverter as close to the battery bank as humanly possible but not in the same compartment.

Whatever wire size you are considering to connect your inverter, go bigger.

We have 300 watts of solar and 4 6v deep cycle Trojan batteries. We can easily run our TV and a computer, but we have a stove top percolator for coffee and don't use anything else off the batteries and inverter other than a Cpap which can run all night without the heated hose and barely draw any power. We don't have kids that camp with us so in 40 degree weather, we don't run the furnace. In fact, if it is going to be mid 30's, we don't run the furnace. The first person up starts the furnace and the Buddy heater if necessary. If we have hookups at a forest service campground, then we also run our fireplace (hey, I know that wasn't part of your question, but it's so nice to have the fireplace).

Hello All,

We seem to be dry camping more and more over the past 2 years. Mostly in state forrest land with dedicated sites but the sites are roughly 1/4-1/2 mile between each site. This spring I upgraded from a single 12v to dual 6V batteries. Now when camping in 40 degree nights my furnace makes it well into the morning and even into the afternoon vs 3 or 4am with the old 12v. So our current routine is running generator for about 2 hours in the morning while we make coffee and breakfast, and then about 2 hours in the evening as my kids are winding down and watching a movie before bed. The rest of the day and all night I prefer to leave generators off and 4 hours seems to be enough to charge the batteries enough to hold over another night.

Anyway,I'd love to cut that back even further and give the ability to run a coffee maker, TV, and other devices off 12v. Please point me in a direction of where to start looking at inverters. Are there good posts explaining how and where to install them? Also, what size solar kit is fairly affordable and makes enough power to maybe cut an hour or two off my generator running?

Thanks!


So here's what i did. This isn't the only way but I'm all in for about $2300 total.

4-130 watt Kyocera used panels from Craigslist. $260
1-Magnum 1000 watt MMS1012 inverter/charger. $737
1-Magnum MM-RC50 inverter remote. $172
2 Crown 240 ah CR-240 batteries. $270
1-Bogart TM-2030-RV battery monitor.$158
1-Morningstar TS-45 charge controller. $143
1- 500 amp shunt. $34
Misc hardware & wiring $500.

The only this I wish i had done differently would be to get a larger inverter. I installed a 1000 watt and wish it was at least a 2000 watt.

We watch TV, run the furnace over night, charge the laptop, charge two phones and run my wifes CPAP machine. Batteries are at about 65%-70% by morning and back to 100% by 1:00-2:00. Basically the system works flawlessly for us.

The solution to coffee is either a stovetop unit, french press, or freeze dried (instant). Then all you need is to power the TV, easily accomplished with a $25 car inverter and a cigarette outlet added to an existing 12V high drain line or directly to the 12V distribution panel in your converter (mine has 4 unpopulated slots, just add wiring and a 12V fuse)
