RE: Equalize Batteries

This is a question I must ask and some of you may know the answer, because I don't. * If I had a RV Controller that had the ability to equalize deep cell batteries and at the same time a solar charge controller and an inverter...that all had the ability to equalize batteries * will they all work against each other to do this task, or are we to have only one of these set to do that job? I hope someone knows Thank you, The "RV controller" I am guessing is the converter. It does not equalize batteries as advertised, it just stirs them every so often when doing Float. The solar controller will equalize at some high voltage it is set for The "inverter" if an inverter charger would have a high voltage equalize setting. The batteries will equalize at the higher voltage between the two but there is no need for both. Just leave the solar on normal, not to equalize and equalize with the inverter/charger. The instructions for doing that will be in its manual. Those include disconnecting the batteries from the rig first, so the 16v equalizing voltage does not damage the rig's 12v systems. Eg the fridge has a 15.4 high limit, and light bulbs can burn out. You need shore power for equalizing since it can take eight hours or so--too long to run the gen.

RE: Horrible, Awful, Stinky, etc......FURNANCE HEATER SMELL!!!

No mice here! When the LP furnace comes on first it smells out of the vents like burning LP, but that smell goes away quickly. So you must be right, there is something else. Did you take the floor vent covers off and use a vacuum cleaner? The vent trunking under the trailer is hard to get at if you have an underbelly. Rusty screws and can't see that close under the trailer with the bifocals--no fun at all! :(

RE: How far is too far for the inverter?

I have a zoo for wiring between inverter and battery, but it is somewhere equivalent to about 6 feet (one way) of #1 AWG with a 2000w inverter and the battery bank (four or six batteries depending on winter or summer) With the 6 batts I get about 0.6v voltage sag when the inverter is drawing 115 amps (as seen on Trimetric). With 4 batts it is more- ISTR 0.9V sag last time I did it. Your sag amount is a combo of battery AH amount and wire gauge amount. The aim is to stay over 11v as seen at the inverter for as low an SOC of the battery bank as you can get. You fatten the wires and add batteries in some combo as convenient.

RE: power gear slide out motor P/N 524664 130-1305

I thought I needed a new slide out motor but it turned out all it was, was the rocker switch for the "in/out" that had worn out. Check that out before buying a new slide motor! ( I did some work checking out wiring including jumping wires here and there to discover where the problem really was.)

RE: IN MH battery charging

Use RV's shore power and converter to Float the house battery bank. Plug in the CTEK someplace handy and use it to Float the engine battery.

RE: Costco GC2 spec

"Now what I am understanding so far is that the acceptable amps of the charge can go up to 80 or so for a 2-GC2 220 (or so) AH battery set in series (right?). If so are you saying the difference in a high amp charge, say 80A vs 35A, might only cut off 10-15 minutes or so of the charge cycle?" No, going higher than 80 isn't worth it. Going lower hurts more the lower you go. http://i65.tinypic.com/167s7x4.png Your old auto charger is not the same as a new one that does constant amps. The old way had the amps taper right off, so it was always slower with the lower amps as they tapered. Yes you can run the rig on the existing converter for Float and when on shore power. Off grid all you need is a single voltage (14.8v) charger that will do the constant amps (that's the hard part, to find one of those) Don't forget that the "single voltage" at 14.8 means it is a "two stage charger" as far as the battery is concerned. It does "bulk" at the constant amps until battery voltage reaches 14.8, then does "absorption" while 14.8 is held constant and amps now taper. Converters that are called "three (or four0 stage" are different in that each "stage" is a converter stage, not a battery stage. Each converter stage is a fixed voltage , say 14.4, 13.6, and 13.2 While at the 14.4 converter stage it can still do the two first battery stages if it stays at that voltage long enough. Mostly it won't stay there that long and it will go to the next stage 13.6 during the battery absorption stage at some point along the way.

RE: Costco GC2 spec

Temp comp with 14.8 means going over 15 when it is colder out, but the inverter still has the same 15v upper limit shut off. This can be awkward! :( The AH capacity of the bank varies with temperature, being less when it is colder. Your AH setting for "when is full?" is not temp comped.

RE: Battery Bank/ Inverter Question

"What I am hoping to do is to configure the four batteries in series for 24V to be able to maximize the power harvest of the eight solar panels at my house (the Midnite string sizing tool will allow this 24V battery configuration with four parallel strings of two panels). If I drop the battery bank down to 12V I can only use four panels at a time." I think I finally figured this out-- ? OK, I get that the controller can do twice the watts with 24 than with 12. This is because the amps out is the same, and the controller has the same amps limit either way. However, the Voc limit stays the same too, so the max number of panels you can use in series doesn't change between 24 and 12. The OP got me going by saying the number of panels changes. So if he can only use four panels in series with 12 but he can use eight with 24, it is the power limit for 12v there and perhaps the Voc limit of the controller; he goes series/parallel to stay inside the same Voc limit when using eight with 24 at twice the power. EDIT--I see he is using two- panel strings, so the Voc limit is with two, so his four on the RV must be also series /parallel. The effective AH of the four batteries doesn't change so you could recharge them faster with the same amps at 24. But they won't act as storage any better for the four or eight panels. No idea how much storage is needed for the stick house. Just making it a 24v bank won't increase the storage capacity. It does allow you to have twice the power to use while it is coming in even if there is no place to store it all. You need a certain amount of AH size bank to run the inverter in the RV. You need enough battery storage to get through the night. You need enough solar to run whatever during the day plus store some more for overnight.

RE: How far is too far for the inverter?

With some (all?) inverter manuals they call for wire to handle the surge amount, which is twice the rated amount, so you can way over-do it by following the rules. You actually "need" wire to handle what you will actually do with the inverter, not just the max what the inverter could do. Same with the fuse size they want. Pick the wire for more than what you will ever do, and then fuse for that wire. Never mind what the inverter "could do." At least one inverter seems to be saying the ANL fuse is what gives it the "surge" capability, by when it will blow, never mind the wire. (If you do more than you set it up for, it will blow the fuse chosen for that wire you actually used. So don't do that again. :) )

RE: Battery Bank/ Inverter Question

Brain trouble here. :( I know that the controller allows twice the wattage of panels when batts are 24 vs 12. I know that half the amps charge 24v batts the same as twice the amps do 12s. So if you do 24-24 at 8 amps DC output that is as good as doing 16 amps output with 24-12. But where does it say you can have twice the wattage on the same set of batts by going 24 instead of 12, so you get the same amps---which is worth twice as much for recharging? Please explain. I know I am having a problem here! :)

RE: How far is too far for the inverter?

If the inverter is MSW it will run the microwave at lower power and pull fewer amps from the battery doing that. Eg my microwave wants about 1500w input, which would be 150 DC amps drawn by a pure sine wave inverter. But my 2000w MSW inverter pulls more like 115 amps to run that MW. Of course the lower power makes for a longer "cooking" time, but this is not an issue in real life in my case. Also the lower amps for a longer time actually gets you a lower AH draw than a higher amp but shorter time does thanks to Mr Peukert.

RE: Costco GC2 spec

Two 6s can take around 70-80 amps as initial charging rate for a fast recharge. You only get a few minutes faster by going higher in amps than that. The problem now is to find the right charger to do that at 14.8v which is as high as you want to go. (Except to equivalent of 14.8 in cold weather, which will be a bit higher voltage, but that isn't the same thing) Now you need a generator that can run the chosen charger. Eg, the PD 80 amp charger is not PF corrected and will max out a Honda 2000. But you could run the PD 70 amper with a Honda 2000 at sea level. So now you have to worry about how high up is your campground. If you fall asleep with the gen running you are not concerned about limiting its running time to do the recharge, so why are you worrying about fast charging? If you are going to stay awake, then you can also deal with a manual adjustable voltage charger like the PowerMax 75ADJ (you might need the 60 amper with a Honda 2000 above sea level) which does not even need adjusting to do a "50-90" recharge. You just leave it at 14.8v. That stops when you shut off the generator at 90% SOC. BTW, a 50-90 on two 6s with 14.8 and 70Amps initial, will take about 130 minutes with the first 30 minutes at 70 amps to 65% SOC when amps will begin to taper while voltage stays at 14.8 for another 100 minutes to reach 90% SOC You can't do it faster than that. You can do it slower. There are trade-offs you must make, such as how big a gen can your rig carry? Cost of things, etc.

RE: Pls define "solar ready" in terms of RV industry

It must vary by RV brand and model. Our Komfort (no longer made) came with #8 wire for the solar pre-wire. One pair from roof (actually was dangling in the fridge vent ready to be hauled up to the roof) to the kitchen where it was taped to another pair going from the kitchen to the battery area up front, dangling there. The idea was to put the panel(s) on the roof and attach the pair out of the fridge vent, insert the controller in the kitchen area between the roof pair for input and the battery pair for output, attach lugs to the battery end wires and connect to battery. This left the controller miles from the battery, so the other way is to join the two pairs where they meet in the kitchen so it is one long pair from roof to battery area, put the controller there with that long pair as input, use short wire you supply from controller output to battery with a fuse you supply on the pos wire near the battery.

RE: How far is too far for the inverter?

... Also how big is the battery bank and battery type for how low an SOC can it be down to before the loaded voltage hits the 11v inverter alarm set point? ... I wish. My cheap Canadian Tire 1000W PSW starts screaming at ~11.5V. Still works though. Not sure how low the V has to be for it to cut off. I had one of those for a few years till I fried it (RIP) and it didn't act like that. It is a re-branded Xantrex if that matters. It might be a question of where you take that 11.5 measurement from. You can get voltage drop on the monitor to battery wire itself. Plus you can get "rounding error" with only one decimal point. Might be worth some cross-checking with different voltmeters at the battery, at the inverter input, and with the inverter's own readout. If it is really closer to 11 than the now observed 11.5, you can then go about reducing voltage drop.

RE: WARNING large inverter chargers

So, still no idea what operating procedure/sequence led to the FET board frying? If none, how can you avoid doing it again?

RE: How far is too far for the inverter?

Hi, How many watts is the inverter? Also how big is the battery bank and battery type for how low an SOC can it be down to before the loaded voltage hits the 11v inverter alarm set point? Then pick how low you might be down to when you want to run the appliance. My own requirement is to be able to run the toaster for early breakfast when the batteries are down to 50% and due to be recharged later that day. Your inverter to battery distance is easily doable with the right set-up, so the distance itself is not an issue.

RE: Why go solar?

Hi BFL13, Actually the Magnum inverter/chargers can do 125 amps @ 12 volts from an 1800 watt shore power supply--so they should be able to do that from a 2k generator. GordonThree wrote: "My Magnum charger will keep pushing high amps right to a 99% state of charge... With a 2000 watt generator it takes about 4.5 hours to recharge my 800ah bank from 50%." I would like to know how this could be done. I can't get the numbers to work. I believe a 2000w gen can't run a 100 amp charger that is PF corrected, but it can possibly run a 75 amp non-PF corrected one. My PF corrected 100 amper powered by my Honda 3000 showed this on the Kill-A-Watt (which maxed the KAW so I was lucky it didn't fry) (loaded voltage showing of course): 122.7v , 15.57 a , 1854w , 0.97 PF , 1910va. Output was DC 102a with batt at 13.95v, charger set to 14.8v. Scale that up for 125 amp DC output, you would expect say, 2385va with loaded voltage a bit lower, say 120v and so 19.88 amps The question is how was he able to that with a Honda 2000 generator rated 13.3 amps? My thought is he had something wrong with his monitoring information, leading him to think he was doing that. If he actually was able to do it, I still would like to know how. I doubt it could be done on shore power on a 15a circuit either, but I don't know what a 15a circuit breaker can take before it pops.

RE: Solar Output in Shade?

If you don't want one big 24v panel just use two smaller 12v panels in series. The only thing is make sure the solar controller has enough Voc input limit for all the panels in series (add their Vocs)

RE: Any downsides tp flipping the axles?

The trailer we had "flipped" was built with the Dexter axles on two rails that AFAIK Dexter did. Like a bogie for a railway car. The trailer factory then welded those rails to the bottom of the Lippert frame each side. To raise the trailer, they un-welded the rails from the frame and put in "spacer" bar that went between the Dexter rails and the frame. That way, the original Dexter kit was not changed and there was no way to disturb the alignment of the two axles and the hangers etc . If it is not done that way, you can have lots of trouble with axle alignment and so on.
