@@andysgarage1 Wonderful. Glad the A/C has been working out. I'm planning things out now and am strongly considering a 12V or 24V system, along with enough battery to run a mini-split of sorts, with the fan, condenser, and compressor underneath like yours to maximize stealth and solar. It'd be helpful to know (but of course you're not obligated, every bit of info. helps!)... A) how long as you running your A/C? Are you running it only during the day when you have good solar, or are your batteries carrying your A/C through a hot night? B) What are the ambient temps and humidity where you have used your A/C? C) What other loads are you putting on your batteries in addition to your A/C? (If you use an induction cooktop a bunch, that would def. be something to consider in sizing my battery bank) D) How big is your batt. bank, what state of charge do you end up with after using the A/C? E) Can your solar recharge your battery banks after a heavy day/night of A/C usage or do you need to use a DC/DC charger? F) What's the max draw of the A/C unit and what is the average A/C wattage used over X period of time (to account for the A/C reaching its set point and cycling on and off, not full blast 24/7) G) How clear have the skies been and what time of year (hours of sun/day) have you tested your system?
@@antigroundhogday I can answer some of these when I have a few minutes. Many of them are however very subjective to my specific specs and environmental conditions.
@@antigroundhogday I've so far used my A/C in full July in FL heat and humidity, I run it during the day to cool off after a run or while relaxing. The most important time is of course at night. even with full solar offset (around 450 of the 525w) It's still drawing 30+ amps. with 400ah of lithium I could make it most of the day but batteries would likely be flat. The most important time for me is through the night, I find that it will keep a reasonable temp through the night but can be a decent swing of temp between cycling on and off. The A/C does not cycle during the day in FL, it's full bore all the time. There is also a huge temp differential between the front and rear of the van even with insulated window covers. The A/C draws around 800-900 watts or around 70A @12v on full blast, I can run everything along with it except my Keurig which draws 130+ amps for about 30 seconds( I've never tried these two together but it would be feasible with my design) , I would not run or size a system to run a cooktop and the A/C at the same time. My stove is propane as induction uses too much power for my taste. Again my bank is 400ah and a night of heavy usage leaves me around 30% from full, solar alone will not replenish more than 30-40% of that so I have a small generator to augment and a DC to DC charger. In everything but full summer in FL the system is amazing, had 80~ degree temps during the peak of the day for a 4 day trip last weekend and 50s at night, used 20% of batteries tops and were easily replenished by the solar. I think anywhere but full summer here the system is perfect. That said it is not getting the whole space a constant comfy temp in midday in July, just passable and cutting down the humidity. My fix for the summer is going to be hanging a moving blanket in front of the bed area to close it off during sleeping hours, this should drastically improve the required cycles. I'm planning a more comprehensive video but I've been too busy with the rest of the build. Hope this helps address most of your questions, feel free to ask questions as they arise.
@@dukedongflap Thanks! And so far so good! I have probably 150~ hours on it so far. Stay tuned for an operational video with some numbers soon, I've just been busy with the rest of the build.
Soudtrack is annoying af. Stop & explain a bit, please. At least explain steps. What's the ° of inclination required for the condenser? What's the orientation of the compressor? All detail of your drain modification was a blur. I've been interested in the Treeligo split unit for my Promaster conversion. But, I'm thinking of a left rear door mount near my power source. I haven't looked under my van but it has me intrigued. Thanks for posting. Look forward to the update.
@@johnwren3976 The music isn't my first choice but copyright free stuff that YT will let you upload is a mixed bag 🤷🏻. There is no inclination requirement for the condenser according to the manufacturer, I just angled it to facilitate installation in the space I had under the van and for oil return to the compressor. The drain modification was just to keep the overhead shelf at a reasonable height. I honestly wouldn't recommend modifying the drain unless you absolutely have to for your situation. Sorry the videos suck, this was an early one, I'd like to think the more recent ones are explained a bit more, but I'm here to answer questions regardless. Updated video with some AC details is coming, just busy completing the build. Cheers
Did you have a chance to do any testing with an insulated van and the heat?
@@antigroundhogday we've been using the van a lot and the A/C has been great. I'll see if I can shoot an update video this week.

Great stuff! Has the Ac unit held up?
