    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?
