RE: How to build a LiFePo4 battery bank.

Time2roll glad everything is working out. Give it a little more time and you'll really stop paying attention to the batteries because they just there in the background working effortlessly with solar at all the tasks within reason. Me personally lfp is the only way now. Until you actually get them and use them, some of the lfp stories sound to good to be true. I know with mine now after 5.5 years and the paces they've been put through it's just amazing at times....no more dead lead. ;)

RE: Amps Draw and Voltage Drop Question 2

I suppose the LFP guys like their furnace fans spinning faster due to the higher voltages they run at. Not only furnace but all 12v items running at peak performance and using the inverter/ 120v appliances is icing on the cake even at a low SOC. ;)

RE: How to build a LiFePo4 battery bank.

Freezing temperatures with lfp is certainly something to think about and have some sort of plan "but" from my experience over the past years unless you will be in below freezing temps both during the day and night your cells should stay above freezing without issue. I've posted before that all my cells (20) have a temp readings, I can see compartment temp and know what outside ambient temp is, even when I was in a strech of nighttime temps of 13-17f, daytime temps 37-45f none of the cells ever dropped below 40f by morning and during the day would warm up to low 50f. Even having a small load 7-9a on the pack all the time will not warm the pack. I would let the batteries charge at what ever the solar would produce and being winter that's not awhole bunch till 9-10 when the sun would get some height and be able to hit the front panels along with the panels down the door side of the 5th wheel. If needed and throwing a hold over charge of 100ah (.2c charge rate) from the inverter/ charger & generator with the cell temps at 45-50f seems not to effect the batteries performance yet after 1,800 partial cycles.

RE: How to build a LiFePo4 battery bank.

If the heating pads are wired directly to the batteries terminal and if needing them because the actual cells are below 32f and not the ambient temp how would a generator help unless you have a heater cube plugged into it throwing heat to the compartment. Are you going to add extra insulation on the walls/ floor to help keep heat in and cold out during the colder months if using them during that period?

RE: 3500w power inverter

I am totally puzzled. What are you going to do with a large sign wave inverter powered by only a 200 AH battery bank? I lived full time for a while and have spent at least 1000 nights in my RV. I have gotten by with a 175 watt, non-sign wave inverter that is only rarely used because I could not find a 12v alternative for charging my camera battery. It would take a huge battery bank and solar system to try to use batteries for running an A/C unit. Even a microwave is more than I would want to power unless it is just for a short use in reheating coffee or the like. Yes, the OP could use a little more battery to go with the larger inverter maybe they'll grow into it? No it really doesn't take a huge battery bank atleast not with lfp and having a larger solar system does help. I run the microwave for long periods of time, use the A/C for a few hours and even when the batteries haven't got back to 100% SOC. Living with everyday conveniences without being plugged in and without rationing power.

RE: 3500w power inverter

My Magnum 3000w inverter has 2a idle draw with enough batteries and solar it's not a big issue just leaving it on 24/7. If you're going to be switching it on and off then it shouldn't matter unless you forget to turn it off. How much PV wattage do you have? 1,280w solar, it has to be a pretty crappy day for the system not to produce something.

RE: Battle Born BB8D

For an off grid home sure. For an rv no sense reinventing the wheel if the wheel already is serving its purpose. Live with in the designed system.

RE: Real life solar results

4-5 times the nominal panel rating in watts is what is normally assumed...so 1600w-h per day out of 400w of panels makes sense. Overcast, small shadows, shorter winter days, etc...can really kill output. This sounds pretty close. 1,280w flat mounted... late fall, winter, early spring I'll average 3.5kwh daily. Late spring, summer, early fall 3.5-7.5 kwh daily.

RE: Battle Born BB8D

batteries will do 3c continously or 1500a, doesn't do much good if the inverter and other components won't allow it though.Wow.. really? What kind of cable would handle 1500a? Exactly....doesn't do much good if the inverter and other components won't allow it though.

RE: Battle Born BB8D

What possibly are you going to use to draw over 200a. My microwave draws 148a, 12c coffee pot 84a, air conditioner 150a+. Now if I forget that I'm boondocking and turn the microwave & coffee pot on and other misc items at the same time then it will be 250a +. Hi Itnerant1, My microwave draws 176 amps. My air conditioner, on a hot day draws up to 160 amps. It is not a problem as my inverter tops out at 250 amps (3000 watts), so I can't run 2 major items at once. That was the point I guess I was trying to say without actually coming out and saying it. The inverter is going to be the limiting factor and the op said a 2,800w inverter. Heck my batteries will will do 3c continously or 1500a, doesn't do much good if the inverter and other components won't allow it though.

RE: Battle Born BB8D

Look at Lifeblue batteries also and compare $$. They have 100, 200, 300ah batteries and if cold temp is an issue they have batteries with warmers in them.

RE: Inverter cooling fan

As Pianotuna points out if your inverter uses the ac to run its fans let it cooldown before turning it off. I run my Magnum for hours powering the ac unit but I make sure that the front compartment is open for air circulation under those conditions. Also the inverter is on 24/7/365.

RE: Transferring fresh water when dry camping

I would fill up the bladder when I was dumping the tanks and taking on fresh water. Some of the locations that I boondocked in it would be hours from civilization or a water source after 3 years of use of the Aquatank2 30 gallon bladder carrying (2,130+ gallons)/ transferring (71+ times) the seam on one side is starting to show a very slow seep, if I was just going from filling location to 5th wheel immediately to transfer it wouldn't be that big of a lose maybe a gallon or so but in some locations we boondock I'll fill it/ carry till it's needed or will fit in the holding tank (7-10 days). I liked the Aquatank2 bladder so ordered another but 60 gallons this time mainly because the difference in price was only $10 and the foot print was only 12" longer. Giving an option to carry up 60 gallons instead of the 30. Any of the big box stores (home depot kind) will have ends for hose that can be used, so yes for a garden hose.

RE: Westinghouse i4500 Generator

MNRon, I looked at the fault history and to be honest nothing looks out of the ordinary.  Just the point when it switches from inverting to pass through from the generator that it just doesn't play well with eack other at times. Here is how mine looked H1 D 6 11:18 Inverting 12.8 -336a (this amp # is the locked rotor peaking from the A/C unit, I know the inverting at time of this happening would be around 10-15a normal minimum daily draw.) BTS:77F TFMER:122F FETS:104F There was a couple of older faults with amp being 110 upto 200a but from the same issue of inverting to generator pass through not playing well with each other. Since raising the load share incoming AC to 16a instead of 15a no more faults.

RE: Westinghouse i4500 Generator

I’d tried a ton of steps too, starting with adding a soft-start, then switching out my Honda 2000 for a 2200, then had some limited success by adding a Hughs autoformer (though not it’s intended purpose…), but uber hot weather was the variable that seemed to always kill the Eco-mode deal…But as I recalled long ago with our previous camper using the same air conditioner (no soft-start), the Honda 2000 would run it while in Eco-mode, so the more and more I thought about it, what came into my field of view was the fussy pass-thru inverter…Sure enough, it turned out that was the problem all along…Either way, I prefer the slightly larger genny for the additional head room, and with the new strategy we can run the microwave or coffee pot (via inverter) and air conditioner at the same time, so in the end I’m truly more than pleased :) 3 tons I don't even try eco mode not worth the hassle. Full fuel tank on the eu2200i lasts exactly 4 hours running the A/C, can put a stop watch to it. ;)

RE: Westinghouse i4500 Generator

Yes the red light would come on while the A/C attempted to start. I looked at the fault in the me-arc along time ago but not the recent one, which should be still there. I wont be back to till Friday to look at it. Other than that glitch which I believe I figured the "work around" by just increasing 1a. The Magnum equipment is pretty robust, that inverter has been on in use everyday since April 2016, inverting loads of 150a a couple times a day up to near 200a+ on occasion, the Magnum PT100 scc has not given one issue at all. The system as awhole with lfp batteries truely has been a set it and forget system in everyday use, it just works quietly in the background while we boondock.

RE: Westinghouse i4500 Generator

MNRon, Before installing the Micro-Air on the unit if I was in AZ (low elevation) during Dec-Apr there wasn't an issue at 15a load share. As I moved north during the summer and climbed in elevation 4,000' or so and ambient temps of 90f was the range that it would be hit and miss with 1 generator set at 15a load share. If I put my eu2000i and the companion eu2000i together and set load share to 30a there never was a problem even at elevations of 6,000' or so. I never ran the A/C unit off of batteries before adding the micro-air. Since adding the Micro-air last year I can use either 1 eu2000i or 1 eu2200i generator with eco off and it will start the A/C unit up to 6,000' or so without issue as long as I have 16a as the load share, 15a is a fault every once in awhile especially if the temps are in the mid 90's. I don't allow it to charge the batteries while running the A/C off of the generator because my 1,280w solar covers that. When I run the A/C off of batteries there is never an issue even if the ambient temps are high. I can watch as the micro-air start to spool up for a few seconds on my display and max's out at 190a before settling down to a steady 13a draw of the A/C.
