Re: Important

Anybody ever had any good luck with a solar panel battery charger? Looking for one to put on the pop up camper for when we are camping without being hooked up to a power source. Was gonna mount a 12 volt battery on the tongue and put like a 500 watt inverter on it so that we could run a little lamp or something at night. Anybody got any recommendations on solar battery chargers.

we had a really stupid law that said you couldn't carry in any place that had an on premise liquor license. So ohioccw lobbied to get carry in a restaurants that served alcohol, because even if you weren't drinking tey were considered a bar. Ohio does not have separate liquor licenses for bars/restaurants. Liquor control wasn't about to implement a system for that (hell, liquor control is still using telephone modem banks to do inventory, they are terrible, I'll tell you my tech support story one day), so when we lobbied for restaurant carry it ended up extending to bars too.

In tn the restaurant cant serve you until noon. However the hot promo in tn is to run half price bottles of wine on sunday. The price isnt much different from the store and if you drink the min amount on premise you can take the rest home

inverter will cut your efficiency drastically. Run LEDs straight from the battery. They'd probably last a weekend without a solar panel, but a 15w solar panel would power them indefinitely.

Re: Important

So you saying to find a little led lamp to use instead of like a 60 watt regular light bulb. Just run it directly off the battery then?

The brewery exemption is the only way I can get beer to my house on a Sunday without driving to Illinois.

The on-premises vs. off-premises difference also explains why a bartender will open a bottle or can before handing it to you. It's not just to be nice or to earn a tip, it's so you don't pull a "can I get 13 beers, please?" and walk out with them.
I didn't know what the rules exactly are, I don't drink but I knew I had seen people drinking in bars on Sunday.

Yes. You want efficiency and low amp draw, inverters = neither of those.

Small solar panels don't put out a whole lot of power, so you have to keep that in mind. You want your nightly draw of charging phones, running lights, etc to be less than or equal to what your panel can recharge during the day.

That's my understanding at least.

Are you talking about outside lights or inside lights?

I just did the whole RV in leds, I can help if I know what your intention is. You want a marine/rv deep cycle battery with as many amp/hours as you can afford. The led bulbs I put in my overhead lights pull 1.7 watts, versus 57 watts for the little 12v bulbs they replaced. I just bought a battery box from amazon designed for jon boats with trolling motors, it has cig plugs and usb ports on it as well as 12v terminals. Useful if you're sitting outside and you want to plug something in. I'm putting it on the trailer for my winch.

Most of your led stuff is designed to run on 12v anyway, so cut out the inverter and run them off of a distribution box and some switches. Be careful how big of a solar panel you purchase, you might need a charge controller. If you change the trailer plug from a 4 pin to a 7 pin on the jeep and the camper, you can run a constant 12v wire from the jeep to the battery to keep it charged while you're driving to the campground and you won't have to try and keep it charged with a solar panel while you're out there.

yes.

converting DC to AC is going to be, at best, about 80% efficient. The rest get's lost as heat.
an incandescent bulb is also far less efficient.

do you want it for around the camp lighting?
get you a string of those rock lights and set them up around the camper for area lighting. They're like 5w per light, so if you setup 6 of them at the corners and sides you'd be pulling 30W.
So figure out how long you want them to run. if you have a 15w panel it will take two hours of charging to put back what you use in an hour of lights. 30w panel is 1:1 and so on.

I also have a plethora of 12V converter chargers here, so if you want a charger so you can plug in at an electric site and ru nall your 12V things without care, I got one for you.

Re: Important

I'm not really worried about outside lights. We have a camp fire and lantern for that. I'm just looking for some light for inside the pop up camper for at night time. I do have some small led light pods leftover from when we did the rock lights on the Jeep. Guess I could use them on the ceiling for light. Just need to figure out how many watts each light draws. Wouldn't think it's much.

Talk to macgyvr before you purchase.

W=VA is all you need to know.
30W @ 12V is 2.5A
so if you know amps, that chart is good. A group 27 battery would provide you 25 hours

most of the SMT LEDs are between 3 and 5W.
anything that's a 5050 style is going to be in that range. 5W is about the max you can go without a heatsink or PWM controller to keep them from melting.

I know that part. I failed at the math for recharging.
