Yes a friend of mine that has a residential ac repair business told me the coils are just not big enough in the rooftop rv ac's and that was why they are so inefficient. I also asked him about the mini splits and he said the problem with them is trying to get parts or even a wiring diagrams to...
Success Took it down this morning and pulled it apart, every thing looked good so I just cleaned up the ring with armature stone. There are no circuit boards inside, pretty simple setup. I remember one of Johns videos where he was talking about the ac voltage being around 60 volts on 12 volt...
My system is similar, I used 150 amp dc breaker off the battery and use it as a disconnect switch also. 4awg is a bit small for battery to inverter, I tried the original 4awg wires that came with the inverter, they were about 18" long attached to BB that was fed with 2/0 cable. The 4awg got...
I have been experimenting with them took a 6 gallon aluminum rv hot water tank and welded in a 1-1/4" coupling and installed a 150 watt 12 volt element. Took about 5 hours to get hot, cant tell you temp but hot enough to burn hand, It pulled about 12 amps, tried a 300 watt and it took 2-1/2...
Yep lots of variables . 2.4 watts to raise 1 gallon 1 degree +or- a little so my 150 watt element would raise 1 gallon 62 degrees in an hour and that is pretty close to what I got with bare aluminum tank sitting outside. I am using the rv tank because it has air gap in the top for thermal...
This week has been terrible for winds pretty much non existent with occasional puffs. This morning I pulled it down and made some temp shims and it gave it 1-1/2 to 2 degree better angle on the blades , put it back up and the winds started filling in a bit . start up stayed about the same but it...
Just for kicks I hooked it up to 12 volt battery to see what would happen using the 48 volt turbine . still using the cheap charge controller that is 12/24 volt. winds are light 4-6 with occasional gust 8-10. It sounded like it was bogging a little so I dropped it and installed the 7 Blade...
Since the 12 volt system is in and the charging system more that likely can't do LFP batteries my suggestion would be a separate 24 volt system for the inverter. A 24 volt inverter charger with LFP battery bank, Looking at youre AC loads at bare minimum you could get by with 2000 watt inverter 3...
Looked it up your average is about 11.5 MPH and if you on a hill top should be a little higher. Hard to give you a recommendation on brand being that I am across the big pond from you. For something cheaper than the Rutland maybe check amazon for a 12/24 volt model AC output
Well to give you an idea of power usage, My Giandel inverter has a digital display that toggles between DC volts in and watts out. The little window ac 8000btu pulls 750 watts in moderate temps and 840 watts when it's hot out, in eco mode if it cycles the fan stops, when not in eco mode fan...
I'm not sure what the rules are but it is common practice to run solid conductor Romex in RV's. My Dutchman that I bought new in 1996 had all Romex with the exception of the shore power cable. I had a few older motor homes before that and they were the same, had friends with newer ones and they...
Did a little experimenting with mounting the turbine. Have it at 15' used 12' of 1-1/2" pipe pinned at bottom so it pivots up and attaches to motor home and so far I am happy with it, was worried about the noise but I dont even hear it inside. When I am done prototyping I will redo it in...
Looks similar to one I bought years ago to play with, 2 blade rc plane prop. The only way I could get it to work was in front of my shop fan. it was fun to play around with though. Last time I looked at it the kittens had ate the wires off flush to the motor
Take a look at a marine schematic it will give you an idea of a closed dc system. basically your positive runs out to load and a ground wire runs from load back to source , no grounding to frame. then you run a extra ground from battery to frame that is not used in system it is there for safety
Hello all
I have always been kinda interested in wind turbines so when I ran across one on amazon for about $140 I could not resist. 24 volt 400 watt rated , anyway tested on bench with drill running it the AC part was good 60-65 volts on all 3 legs but the dc charging side was low, 3-1/2...
Just take a look at ebay, some of the claims on max watt output are crazy. I was just looking at a 8000 max watt 24volt 1.3m diameter 3 blade for $150.00 . Shure doesn't help the market
I used the 63 amp switch from the link to amazon, the 3 phase 3 leg was what I wanted, completely isolates GNH from inverter to shore/generator. Been installed for over a year now and ran roof ac on shore power for over a week last summer and the switch stayed cold
The roof looks good, Mine has aluminum roof and it gets hot enough to cook on. Ambient temps make all the difference. Have had a cool down here for a few days mid 90's and the little 8000 btu window ac was working great sipped power compared to 105f . I think what I am going to do is run a 5000...
Yes one of those white vinyl covers that cover the 3 windows plus the insulated sun shields on the inside front.
There is no overhead anymore this thing was a 22' class C that we bought new in 1996 unfortunately they did not know how to build it without water leaks so 25 years latter had rot...
Yep something wrong with it. I have 24 to 12 step down also no issues there. I have run mine hot an heavy with no problems , I did pull it out of cabinet and mount on wall for better cooling. the original battery cables that came with it would get pretty warm so I swapped them out for 2/0.
When...
Well it was user error Yesterday when I turned on the AC I had glanced at the meter just looking at battery state bars and the smiley face thinking it was almost at full charge, not even close and I only had 400 watts of panels hooked up with an overcast day. I hooked up another 400 watts this...
Well yes and no , I can still disconnect at the fuse panel by pulling out the spade fuse for each panel or series panels. If I was wiring all panels to junction box on roof with one hot and ground going down in coach I would defiantly keep the MC4's or similar
I played around with dorm fridges ,10 CF fridge, and 5 CF chest freezer in the rv . The problem I found with the fridges is leaving them on 24/7 without using ac or heater you have problems, winter when temps drop below 50f they don't run and the freezer defrost summer when it gets 105F they run...
My decision to switch to 24 volt was not scientific, based more on gut instinct. Thought about golf carts running on 36 and 48 volts with 6 volt batteries and here I was running 4 of them 2S 2P trying to pull high amps at 12 volts figured maybe the batteries just cant handle that so well so...
