RE: Charging 4 12-volt house batteries with portable charger

Yes, I had read your screwy 31 thread... rather enlightening for sure. that would be a understatement.

RE: Charging 4 12-volt house batteries with portable charger

Ahhh for the good old days when rigs only used power if you turned on a switch. No blower on the furnace, no pump on the water. no control boards and you lit the pilot yourself. On the downside, those furnaces took forever to warm up the rig. It was a pain to go out and relight the pilots when they blew out. My brother and I took turns with a bike pump on the water system so the old folk could take a nice hot shower. Then they tossed our butts in the lake with a bar of ivory. (it floats) Our rigs biggest issue was we never intended to go back to boondocking. We had roughed it for decades and were going to see how the other half did it. One trip in campgrounds and we found out we couldn't stand being crammed into a tiny spot with noisy neighbors. So we were stuck with a rig that couldn't go more than a few days without life support. Had i done what was recommended back then, I would have mounted the two extremely mismatched panels and confused the heck out of the recommended controller of the day, the Rogue 30a. Even Mark at Rogue didn't mention the problem with mismatched panels, I figured it out in my yard testing. AGM was and still is the best thing since sliced bread and back then I had a line on four Lifeline AGM 8-Ds. They would be toast by now as my controllers, converter and home chargers wouldn't do well with them. I would have a very expensive generator that would never get used. Oh wait, the solar system would be messed up and the AGMs dieing, so maybe I would need it after all. ;) Being able to test different panels has been a blessing. Try to tell someone about the results and they will read the hype off of a web site and tell you are wrong. They will never know the difference because they buy one type of panel and that's it. If a mono panel takes a nose dive, well it's cloudy stupid. what did you expect. Niner, I wouldn't pick on you, well no more than anyone else I suppose. lol I think that anyone here that has worked out their systems to meet their needs is doing pretty well. I would never tell another that they were wrong considering my set up is about as far from recommended as you can get. Too much solar for the banks, batteries that are being used for things they were not intended for. My generator, inverters and controllers are all cheapies. It's amazing we haven't blown up and lit the forest on fire. lol All I am saying is wouldn't it be easier to have a sticky labeled "Taking your rig off grid? You need...." and then list every high dollar, most recommended equipment that full timers need because they depend on it in all conditions.

That was a sweet game on the 39 inch in the S&B.

Not the OTA channels here. They may not be 1080p all the time but the major networks are especially for sports.

RE: Proper Wiring for two controllers to one battery bank

Over the weekend I'll have all three of my Eco-w's wired up. :)

RE: Charging 4 12-volt house batteries with portable charger

Even better is the person that wants to dry camp for a weekend ending up with a pair of 6v's, a 2000w generator, solar, a new converter, LEDs, a portable propane heater and NOW..... low power TV too. lol I am glad people buy the stuff though. What is interesting is seeing what is hype and what is real with all the high dollar gear. Sometimes the small usable advantage is so over hyped and there is always a downside beside the extra cost. With some batteries it isn't just their cost but the cost of the controller/converter needed to keep them up. I have a year or two left on my banks, I hope you guys find the holy grail soon.

RE: Time to charge a bank of 8 6v batteries using a generator

That's a lot of power, battery and solar. Paralleling more that two banks can be a issue keeping the charging and discharging in balance. You could run them in series for a higher voltage inverter and then convert down to run the trailer. Our loads, bank and solar are half of yours at least but our 720w solar is on the ground so far. That'll give us 50a any time the sun is out. The 100a or so you will see will not only work on charging, but once you get to a point it will start running the rig with what the batteries don't take. The only time our batteries are out of float is over night when we use little power.

RE: Repaired Samlex inverter not working at night

More info please. Is there a possibility of the batteries being under charged or that there one bad apple in the bunch. It wouldn't show as easy with the solar holding it up.

RE: Amerilite 21ft (gulfstrem)

Congrats on the Ameri-lite. We have had ours for four seasons and it's been perfect. We we suppose to get a 21MB when we bought but decided to sleep on it as it was closing time, or so they told us. They sold two of them after that and we ended up getting the 25BH.

RE: The 12V power source solar panel

I am just glad that like solar, there are a lot of people using a variety of batteries successfully because they know the care and feeding. By the time my current batteries need to be replaced, I'll know what will fit my needs best.

RE: The 12V power source solar panel

I'd lower the voltage and let the solar help the battery run the inverter. The volts will come down either way.

RE: The 12V power source solar panel

But that is one of the advantages of the portables. I get my sun early on, then clouds. Those clouds may come in banks with spots of sun in between. No matter the time of day, I can get the max possible when the sun does show it's face. Getting to float in two or three hours may be the same as getting to float with a generator, but that's not a 100%. That takes hours at float. You can always set the panels out when you get back.

RE: Solar and battery help

I have the Interstate grp 27 and it's 95 ah new and fully charged.

RE: The 12V power source solar panel

Hmmmm How to put this nicely.... You aint gonna get squat. Even the 24v 230w poly only got 4a under heavy clouds on a cold, cloudy, fall day. That barely did more than stretch our grp 27 for a day and a half before the sun came out. We were down to 12.3v and would have had to charge up that day even with the panel. (40 daytime high, 20s at night) It just wouldn't have taken another full day and night with the stat set at 74F. Adding the twin 245w systems wouldn't have helped either. They are mono's and would have been asleep under those conditions. They would have kicked some tail when the sun came back. :)

RE: Solar and battery help

Lots needs to be considered to properly set up solar for your rig. You can base it on how much power you use. How much battery you have. What kind of conditions you are in. Honestly though, it's a combination of all of them. A properly balanced system starts with you knowing how much power you use daily. You need enough battery to support that use for X amount of days. I say X because it is affected by room and budget. Once you know how much battery to have, get enough solar to get them back up quickly after a few days of clouds. A prudent thing to have is a back up means of charging for when MR sun doesn't play nice for too long. Now that you know how much solar to get, balanced with amount of room on the roof and budget, you can start thinking about which panel/s fit your needs and conditions the best. The most efficient panel in bright sun sucks in lower light. The panel that can provide in lower light is huge in foot print for the watts it produces. The choice is a balance of room, budget and production. In the end you may have to compromise. One thing I have learned about batteries from the forum is that some of the cooler ones are just a PITA to keep charged up. I have the same grp 27 as you and it is easy to keep up. I would have to replace my charge controllers and converter to switch to fancy AGM batteries. Again, making sure al of the components work well together is part of the balance. You asked about the watt vs AH ratio. We have 720w of panel for 345 ah of battery. That gets the batteries up fast when we have limited sun and keeps them in float all day unless we run a big load like the microwave. Even then the recovery is very quick and the batts are always fully charged by night fall. Loads that are smaller than the output of the panels are not seen by the battery at all. The TV/sat runs all day and never has a effect. next year I'll run a 5000 BTU AC unit and if it doesn't run straight off the panel, what comes out of the battery will be very little. My panels are huge and not 12v, so I'll let others advise you on the proper set up.

RE: Dual Trojans and furnace

Charging through the 7 pin is extremely limiting even if you have beefed up the line and installed a isolator. I have used the truck for charging but with a HD pair of jumper cables. Now 12.6v resting after a day of charging is pretty low to me, even with the 7 pin. Also just using a volt meter can be deceiving. I took a 8-d down to 12.1v and hit it with a 12a solar set up for 5 hours till the sun went behind the clouds. By the end the charging voltage was only 13.1v and after resting a hour was 12.7v. That was false because the system had returned at best 60 of the 120 ah removed. Even a light load would have exposed the truth that the battery was only 3/4 full. After that I plugged in a charger and finished the job. The solar may have finished the job the next day but I'm not leaving a battery half partially charged if I don't have to.

RE: Propane furnace battery usage

I would suggest some driveway camping. You really should know what you are up against before you find out the hard way. It is important that those batteries have a full charge before going. Even though I keep my batteries up between trips, I put a charger on them 3 days before we go. I will say these threads are interesting. What, you only have TWO batteries and you are going to try to run your furnace? YOU ARE GOING TO DIE!!!!! Our trailer has had the same 95 ah grp 27 that came with it for four seasons. Our night time temps are in the 30s mid summer and below freezing spring and fall. We run the furnace every night and after a long weekend the resting voltage was down to 12.3v. We were being extremely conservative not knowing what to expect. Now we have solar and are total pigs with the power. The battery is fully charged before sun down and reads 12.57v resting the next morning. We light the rig end to end with LEDs and set the stat ay a comfy 74F day and night. Next year I'll get a pair of 6v so that we can go more than a few days when it is cloudy. So every rig is different. Get those batteries charged up properly and see what YOURS can do for you. LEDs are inexpensive and make a huge difference.

RE: Dual Trojans and furnace

Hmmm I know every rig is different in many ways but we ran our furnace for two nights when it was 26F and on the third day the resting voltage was 12.3v on a single grp 27. How did you make sure they were charged before the trip?

300W would be a nice portable. On MPPT should get you around 20a.
