    24v 2000w wrong input voltage readout

    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...

    YES: RV Solar/ Li/ and AC running full time

    Doesn't Ampere Time make a 300Ah also ? you might be able to fit that in there. I am running 2 Ampere Time 24volt 100Ah in the Rv now with no plans of going more. Plan is to keep solar charger in the rv and just hook solar panel from trailer to it but if I can salvage the AGM's I might put them...

    24v 2000w wrong input voltage readout

    I have the same inverter and when it is under a pretty good load it always shows about .5 volts less. The one time I had problem it turned out my batteries were a lot lower charged than I thought

    Using DC to DC charger to run AC ???

    Without the Dc to Dc charger, going direct to AGM's maybe . but if your limited to the 40amps @12volt and running standard rv roof air you will be out of battery within a couple hours

    YES: RV Solar/ Li/ and AC running full time

    Yep last hot day my solar started going in the negative by 5:00 pm by 9:00 pm it was still 91f and I was 1300 W/h in the hole

    YES: RV Solar/ Li/ and AC running full time

    aangel are you running 12 or 24 volt? Speaking of batteries I am in the process of trying to rejuvenate some 250 AH AGM's, 4 of them, they were in a sign trailer that I just got to make a solar trailer out of. Figured it was worth a shot because they are $700 each and 1000 AH @12volt is a lot...

    YES: RV Solar/ Li/ and AC running full time

    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...

    YES: RV Solar/ Li/ and AC running full time

    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...

    WOW! Absorption fridge vs compressor fridge

    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...

    YES: RV Solar/ Li/ and AC running full time

    Wow it takes a lot of solar to keep up with ac, being conservative keeping thermostat 78-82 it takes 2000 watts of solar to have the extra head room for water pump ,hot water heater ect. and we have had some mild heat here 100-102 days and 70's at night . I don't think I will give up the genset...

    YES: RV Solar/ Li/ and AC running full time

    I have thought of that myself but have not seen any yet. also thought about flex panels on the outer end of the awning just install eyelets inline with the panel eyelets for attachment but not sure how good it would be if the wind picked up

    YES: RV Solar/ Li/ and AC running full time

    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...

    YES: RV Solar/ Li/ and AC running full time

    Thanks for the update, sounds like the Senville works a lot better than the 8000 btu window unit I am testing. About 100-102f outside now sun beating down on the van cab end and it is running constant maintaining 80f inside at about 800 watts

    Which Battery/Batteries

    Can't say what the best option is but I put in a Ampere Time 24V 100ah about a month ago and I was impressed with it so I installed a second one about a week ago, so far I am happy with them

    Ampere Time 200ah batteries small storage capacity

    One thing, the batteries need to be fully charged separately before hooking them up parallel. You didn't mention that you did that?

    1800 watts solar panels

    250volt 85 amp Victron comes to mind if your running 24 volt battery system

    YES: RV Solar/ Li/ and AC running full time

    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...

    YES: RV Solar/ Li/ and AC running full time

    Interesting thread, been eyeballing the mini splits for a while now . I have been trying to figure how much solar I need for the Coleman rooftop ac and thought I had it figured out till temps reached 106f , direct sun switched to high fan/cool and it started pulling just shy of 2000 watts so I...

    3S3P solar panel config

    Hello All Quick question with 3S3P panel config with the 3S facing different directions IE 3ea facing up 3ea facing east 3ea facing west , would it need 3 charge controllers or would a single charge controller work the same or even close to same ? What I am thinking about doing is making a...

    Lower Power Than Expected - what's normal?

    Yep, Doing a little testing today, just added second battery 24v 100ahr. with 2200 watts of solar going through 2 charge controllers with RV roof ac running, I'm getting 1100 watts into the batteries at 9:45 am so we shall see what I get around noonish. Pretty clear sky today

    Lower Power Than Expected - what's normal?

    What you're getting is about the same as I'm getting, close to 70%, I bought a bunch of used 180 watt poly panels and I get the same % as the newer Renogy 100 watt poly or mono panels. I was using epever charge controller so I switched to Victron 60amp smart solar new with all new wiring and mc4...

    Please check my design.

    Good question on the converter ,mine is the 30 amp model and it just seems to work, worst I did was run a 150 watt water heating element for 5 hours and other than the converter housing getting warm the wires were fine but the 12ga wires are only about 6" long

    Please check my design.

    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...

    manual transfer switch ?

    Yes it is in your 4th post and it would be the 63A 12 terminal switch in the list of switched available

    manual transfer switch ?

    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

    How to run wires through the roof

    Yep pros and cons to ether way. I wouldn't think it would get hot enough to burn wires, on the older ones we use to put 12 volt fans up in the vent to help air flow, never had any problems

    How to run wires through the roof

    What I have seen on some Rvs with rubber roofs is they run the wires down through refrigerator vent

    Is this correct? and advice on buying a small wind turbine

    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

    Is this correct? and advice on buying a small wind turbine

    As far as wind turbine it is all about the wind speed . What is your location and average wind speeds throughout the year?

    Small wind turbine

    Wow this is nice getting some winds today 18 mph was the highest I got on the hand meter with some gust higher. 60 watts was the highest output on meter and accumulated 139 WH in the last 5 hours. Overcast so solar input is low about 3.5 amps from 400 watts at 3:00 pm. Still not sure how I want...

    AH rated vs actual and voltage drop vs actual current draw?

    I think the 14.2 volt may be the problem, not getting full charge. On mine they run 14.6 . The 12 volt dual purpose is it a sealed battery? and the GC2 flooded ? usually it not to good to mix battery bank batteries

    Small wind turbine

    I did a little research and found that is normal 1 to 1-1/2 volt loss and it comes out about 1 watt loss per amp, I am drawing 12 amps so a 1 amp loss would be about the same as mechanical relay power draw. At the moment I have it hooked running the ground through the relay and it works the...

    Small wind turbine

    Frustrating got my 40 amp DD solid state relay with the controller in. The controller is great finite adjustments even the time delay but the relay I am not impressed, conflicting info on wiring the load side , the manufacture says the load side is the #2 + and battery is the #1 - well that...

    24v GROUNDING HELP and overall critique

    Maybe I can shed some light on why you should ground to chassis, without a ground to chassis if you get a short IE positive Dc or the Hot wire on ac to chassis it will not blow a fuse because it has not made a path to ground, what it does do is energize your chassis and given the right situation...
