We use our UPS in a 911-Police-Fire dispatch center. We have power outages weekly! UPS is backup in case one of the two Komatsu Turbo Diesel generators don't start! That happens when the block heaters fail in winter.

Nice rig Mo! Those tri-axle Airstreams look really cool!

Man! I guess I sure can't complain about DP&L's reliability or response time for that matter.

I'm considering one (or two for A/C) of the little Honda EU2000 generators if we ever do get into boondocking. I don't think other campers would like my International Harvester Turbo Diesel generator (F250 PSD) running next door!

Thanks, Pick.

Keep in mind they are significantly larger than Group 27 batteries and might not fit in RV battery boxes.

This is true but BlueSea Systems makes a battery box specifically for two T-105s. It is designed for marine systems so it protects the batteries on the tongue of my Airstream very well.

In my opinion, yes. 1.5 watts is a very very small amount of power, and that would be under ideal conditions. I have 2 55 watt panels, now that the sun is getting low in the sky the power output is down to .8 amps, and that is only for a very few hours a day. Solar cells are great under ideal circumstances, but if they aren't facing directly at the sun they just don't put out any power.

I'm with John on this one. I bought a different brand small plug-in unit similiar to this for my kid's Camaro. I'm not really sure if it made a difference. He had a "make the car smell good" device plugged into the cig. lighter all the time and was running a big stereo. We replaced his battery 3 months later. Now this could have been because the battery was of questionable strength since we bought the car used but who knows. Go to www.unisolar.com and look at their flexible solar panels of 5,11 and 32 watt. I would think a 5 watt thrown on the dash or a 5/11/32 watt thrown on the roof or awning would keep things charged fine. They also have protable units of 10, 15 and 30 watts as well as 3,5,11,21,32,42 and 64 watt framed units. Higher the wattage, larger the panels.

My 5 watt Solargizer solar charger/maintainer panel has kept my 2 Delco Voyager 105 amp hr. batteries charged during boondocking for weeks at a time.

Solar charging

If your Voyager batteries are 12volt you have about 2500watt hours of power. For a 10 day trip you could use 250 watt hours per day before running completely out of power. A 5 watt solar panal running a full capacity 10 hours per day would supply 50 watt hours of power, enough to offset 20% of your maximum potential use. But a more realistic figure would probably be about half of that, or 25 watt hours, given the changing position of the sun and overcast days. It could take as long as 50 days to fully recharge those batteries. I wonder if your system has a significant effect on keeping the batteries charged on your outings, or if you are just using the capacity of the batteries
.
I know from experience, though, that you can get by on these outing using a minimum of power. In my cabin I just use the solar sytem for lights, a radio, and a very small bathroom fan. I typically run a couple of 6 watt halogen lights for just 2-3 hours. That only amounts to about 36 watt hour at best. The radio and fan may bring tht up to a total of 50 watt hours per day. At that rate the batteries alone should last approximately 7 weeks.

Charles,
I start with fully charged batteries and am frugal with my light use. I run one but no more than 2 lights at a time and don't run them for long. I have run 2 fans for 3 hours in one day and then one fan from 9 p.m. until 4:30 a.m. when I got up to go deer hunting. I then had a couple lights on for 45 minutes then turned everything off until I got back around 11:30 a.m. The fans went back on for a couple hours while I snoozed before going back into the woods. I am not using my water pump at all. I get back around 6:30-7 p.m. and a light will go on to fix an evening meal. If I leave the trailer to sit by the fire while I eat then I will turn the light out otherwize I will have the gang eat in the trailer with me (with front overhead light on of course). I may be saving power by the fact that the light over the sink is a single bulb and another a couple feet away has 2 bulbs. The light over the dresser has one bulb but I sometimes opt out for the multiple bulb reading light on the wall over my pillow. I've never experienced any power problem, dimming of lights or whatever.

Thanks for the comments as I thought the little panel was too inexpensive and underpowered to do much.

My house batteries stay charged, as they remain much of the time plugged into a/c in my driveway. It's the auto battery I am concerned about.. I have used a trickle charger on my old car, and thought maybe a solar version would keep it juiced up in the motorhome when its not been driven as often.
I will routinely drive it once a week, but that isn't long enough to give a good charge to the auto battery.

I also run my generator once a week, so I may be concerned for no real reason. The last battery lasted 4 years.

As long as you are normally plugged in you are in much the same situation as me. I have a float charger mounted in the battery box that I plug into the external outlet on the MH. Keeps them charged and only the extension cord to unplug.
