RE: Soft start/Easy start

The Micro Air is awesome, we love this upgrade. If you have a 2000-ish watt generator that is marginal for running the typical RV air conditioner, the Micro Air will save the day. In our experience anyway. I'm not sure if it has any benefit if you already have enough generator to run your air con.

RE: WFCO 55 amp converter operation

I have had issues with bad connections and bad batteries in my motorhome and have them all resolved except knowing how this converter should work. It charges a new set of batteries to about 13.6V with no load. When I put a load (2 fantastic fans and a 12V TV) on the batteries the voltage slowly drops to about 12.65V and seems to stay there. If I shut the converter off it drops even further so it is doing something. When the load is shut off it takes about 20 mins for the voltage to get to 13.4V. I think over a longer period it will get to 13.6V. I have a friend who has a progressive dynamics converter and he says when he puts a load on the batteries the voltage drops from 13.3V to 13.2V and never goes lower. Do I have a bad converter or does this type just act like a trickle charger? Sounds like a bad converter or connection issue. I have the WFCO 55 in my camper and when I switch it on it immediately jumps to 13.6V. I can put all manner of minor 12V loads on it and it won't budge from 13.6V. Minor loads meaning whatever OEM 12V equipment in the camper you want - water pump, lights (all LED in my case), exhaust fans, furnace, etc. I acknowledge that my batteries are usually at a decent SOC so I'm not talking about what happens when my batteries are quite low when turning the converter on.

RE: New to the TT world

The brand of the equipment is Mastervolt.. I priced each component and it seems expensive to me.. do you think Mastervolt brand is junk? No, I just mean that I'm not familiar.

RE: New to the TT world

I didn't know RV manufacturers were selling upgraded power systems with claims of running air conditioner. Someone chimed in that the 400 ah LiPO4 battery system with 3000 watt inverter/charger and 570 watt solar were typical of mfg-supplied junk, but based on the numbers that is absolutely not true. That is a very nice sounding dry camping setup, although I can't vouch for the quality of the components. But as has been mentioned repeatedly, not enough to run your air conditioner for a usable duration. Even your caveat of only a couple hours of day will take most of your battery capacity, leaving you short on battery to operate the rest of the camper when boondocking. And then you start the next day at super low SOC on the battery with little likelihood of your solar getting enough harvest to get you up to >90% again.

RE: Easy Start By Micro Air

Just another plug for the Micro air easy start, I installed it a handful of years ago and our Yamaha 2400 runs the 13.5 Btu A/C great. Usually I'm very diligent about turning off all other 120V AC loads when I do this, but this weekend I ran it for a while and later realized the fridge was on auto so it was using 120V AC power when plugged into the generator. Fridge draws 300 watts on electric and I suspect it was on the whole time because it was hot as heck out. Converter was off.

RE: Battery and Solar woes

For reference, we have 280 watts of solar mounted fixed and flat on the roof routed to a Morningstar PWM controller charging 2x6V GC batteries in series. We only boondock and power is usually never an issue for our long weekend warrior style of camping. I'd say we are moderate power users, we run an inverter and use some gadgets but no high draw items. Occasionally a 300 watt electric rice cooker.

RE: no power to 12 volt battery with shore power'

Nevermind, I misread the OP.

RE: Electrical Help pls

OP, give yourself credit - you are understanding the AC to DC conversion thing and that you need the current * voltage to provide the watts! Also the reality that while electric heat is efficient, it is not practical in a small portable battery system. I kind of went on a similar path when I first started using our camper. After installing solar and upgrading battery capacity I figured I should use it to operate a 12V heater to take the edge off at times. But I quickly abandoned it and tossed it into the bottom of the camper gadget pile. So recognize that even a 12V heater that eliminates the need for an inverter at all will still not be great if you are using the stock 12V plug in the camper. In my camper I have another 12V plug that I wired in using some relatively large wire (8 gauge I think?) and it makes a huge difference on how that little heater performs. It can run when plugged into the stock 12V plug, although it barely produces heat. When I run it plugged into my fat-wired 12V plug it puts out pretty good heat. But it isn't warming a room up. Of course it is only a 150 watt heater/DEFROSTER and defrosting a windshield sounds realistic. https://www.macys.com/shop/product/wagan-12-volt-car-heater-defroster?ID=10421642&pla_country=US&CAGPSPN=pla&cm_mmc=Connexity_PLA-_-n-_-n-_-n&m_sc=sem&m_sb=connexity&m_tp=PLA&CAWELAID=120156340009470470&m_ac=Connexity_pla&m_cn=n&cnxclid=16558304238181453857810070302008005

RE: Disadvantages of flipping trailer axles?

It can make the last step from your stairs to the ground a big one. We use a sturdy stool on the ground to make up the difference. Other than that, no issues that we have noticed. https://www.amazon.com/Camco-Adjustable-Step-Supports-Construction-43676/dp/B00G258I0G/ref=asc_df_B00G258I0G?tag=bingshoppinga-20&linkCode=df0&hvadid=80608001419687&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=&hvtargid=pla-4584207577681122&th=1

RE: Charging 6v golf cart batteries?

12.6 volt is not charging. 13.6+ is charging (IE 13.7) 12.6 is resting voltage of battery. And yet "12.6 VDC current 15 AMPS" is exactly what the OP's converter says on it. It doesn't make sense to me, I think OP needs to yank that out of there and replace it with a modern/proper converter. And read this. :-) http://www.marxrv.com/12volt/12volt.htm

RE: Atwood water heater drain plug tightening

I have always had to use tape to get a good seal between nylon plugs and my Atwood water heater. It seems to me like the nylon plugs would not need tape, but every season when I go over the system and don't tape the plug, water slowly leaks from the plug. Depressurize, remove, tape, reinstall plug, no leak. I've gone through a handful of plugs over the years, so it's not like it was one janky one that leaked.

RE: Rivan truck tow vehicle

Cool, thanks for sharing. I am very curious about EV options and I like the idea of something I could tow with. I want to see what kind of mobile solar charging options people come up with. I'm not talking about an unrealistic perpetual energy situation. But more like I'm boondocking for a few nights, can a large array on the trailer/camper recharge my electric vehicle to full during my stay?

RE: DC to AC help

Thanks! I like the simplicity of your method of simply plugging the shore power cable into the inverter, but doesn't that cause the batteries to try to charge themselves? With onboard chargers in the camper any time I have AC plugged in the charger is on. Does this cause a problem? Edit- Actually, I see you dedicated a breaker to the onboard charger so you can isolate and turn that off. Found a youtube video of this exact install. I guess the only downside is having to change the shore power cord back and forth from inverter to generator throughout the day. Thanks again You got it, converter must be off when doing it this way. I personally have my converter off by default and rely on solar. Converter would be a backup charging method which would then trigger the need to hit the switch. When we camp in summer heat, then the generator comes along for running the air conditioner. But otherwise, no swapping going on and we're plugged into the inverter for the whole stay.

RE: DC to AC help

Curious, where did you mount the inverter to make in convenient for your shore power cord? Also, what size inverter do you run and off what size cable from the battery system? Thanks! Front pass through storage of a travel trailer. Battery connection is about 5' of 2/0 gauge.1500 watt pure sine wave inverter

RE: DC to AC help

My technique is similar to pianotuna's. When boondocking I do the following: 1. Fridge and water heater on propane 2. Disconnect converter. I isolated my converter's power supply to its own AC breaker that I switch off. I also have air conditioner, electric water heater, and microwave breakers switched off to avoid accidentally running them (too much load for my battery system) 3. I plug my camper's shore power cable into the inverter's AC outlet. 4. Turn on inverter, now all outlets are live in the camper.

RE: Starlink for RV's Just Released Announcement

^^What Walaby said. It isn't turning into rich man's service in remote area, it has added a portable/RV option for those that are asking. And they charge you for it, but that's a business addressing a demand. I think the logic is you take your dish with you when you RV, not buy 2 different setups and 2 different plans. The dish easily separates from its mount and unplugs, you need to have a base or mount for your RV and bring the starlink router with. You'll need another connection cable as well, now that I think about it. Unless your home one is easily taken with, mine would not be. Now if part of the family stays home and needs internet while the other travels in RV and needs internet, then you're talking about 2 full setups. My home Starlink had the $10/mo increase which is a bummer, but it is my best source of high speed internet as well.

RE: Explain how emergency trailer brake gets power?

To clarify, I confirmed that the brakes are wired to operate off of the trailer battery. But the trailer does not have a separate battery dedicated to brakes. In a previous job I drove a work truck hauling an equipment trailer and that trailer had a small battery on the tongue that was only for the emergency brake system.

RE: Explain how emergency trailer brake gets power?

Okay I was able to confirm that the two wires going into the side of the junction box along with the main 12 volt do come from the breakaway switch controller. When I pull the pin from the breakaway switch, I observe about a 7 amp draw on the batteries. So things seem to be working as designed.

RE: Explain how emergency trailer brake gets power?

That connection is inside the junction box where your 7-pin cord terminates at the trailer. The breakaway switch is wired to both 12v positive from the TT battery and the blue brake wire. Thank you, this seems to correspond with what I'm remembering and what is in the picture. I'm pretty sure the 7-pin cord comes into the bottom of that junction box where the sun-baked red 12V wire from the circuit breaker is entering from the side. One or both of the other small gauge wires are coming from the back of the breakaway pin box if memory serves. I'm trying to remember all of this as I sit in the office and the camper is at home. I'll go check some things out when I'm hom.

RE: Explain how emergency trailer brake gets power?

I bought the camper new from dealer and the only rewiring would have been by me. I'll have to do some testing to see what happens. If I remember right, the wire from the back of the breakaway switch went back into the junction box on the frame where the main 12V supply to converter/power center. I found a photo I took for another purpose which I've zoomed in and cropped down. I think the gray wire(s) are from the breakaway switch. https://i.imgur.com/GdKhjo8l.jpg
