  • Post in thread: Easiest solution to provide generator "boost" for HVAC peak inrush

    I have a portable A/C I use to cool a 250sqFt room at my cabin when it's really hot. It was like ~$260. All of my windows are casement in that room. It works quite well to cool things off.
  • Post in thread: DC Fridge or AC fridge with inverter?

    I do have a wireless. Good point, opening the door does skew the results, I think.
  • Post in thread: Aframe Solar Set Up

    Be advised that I have found that at least on my 2022 Aliner, the zamp connector's polarity is REVERSED from standard SAE. Sneaky move on zamp's part to force you to use their way more expensive solar panels. You can buy an adapter for like 2 bucks to fix it.
  • Post in thread: HQST MPPT 40amp Charge controller.

    Hey thanks for the effort, really. Unfortunately, that's not quite the same unit, rebranded or not. The unit I was inquiring about is this: https://www.amazon.com/dp/B09J16G1LV?psc=1&ref=ppx_yo2_dt_b_product_details The bougeRV unit on the discussion you linked to does not have integrated...
  • Post in thread: HQST MPPT 40amp Charge controller.

    Mine continues to work fine, series or parallel.
  • Post in thread: DC Fridge or AC fridge with inverter?

    Yep, you correct, reefer. I meant this (in jest): https://www.urbandictionary.com/define.php?term=reafer Edit, on further research, the former is the primary usage. lol.
  • Post in thread: Predator or Champion?

    Your Honda is easily convertible to dual-fuel, you know. I like propane as a fuel, but when I boondock, I need it to run my fridge and heater and for cooking. Propane also has a lot less energy, and has a larger power loss at higher altitudes.
  • Post in thread: Where is off-grid utopia?

    And soybeans, wheat, millet, etc. But the Cornhuskers are pretty horrible anymore. lol
  • Post in thread: HQST MPPT 40amp Charge controller.

    I am unfamiliar with the E02 error. I haven't experienced any errors yet with my setup. I can only speak to my experience with my rebel 50aH and the SOK 100aH. They have both been trouble free for the period I have had them. (1 year rebel, 4 months SOK). I see from the manual that the E02 error...
  • Post in thread: Ham Radio and Inverters

    My radio's run on 12V, unless an amp is needed, I'm good to go. Throw some wire in the trees, and i'm there.
  • Post in thread: Getting to bulk mode charge mode

    Well, the HQST mppt controllers can be linked together, and are quite reasonable. https://hqsolarpower.com/40a-mppt-solar-charge-controller-with-bluetooth-lcd-display/
  • Post in thread: My parents are moving into a parked 50 amp RV inside 11 acres to be near my aging grandparents. Please help design their off grid solar system?

    Just sharing my absorption fridge experiences. I have had 2. A 3-way (12V, 120, gas), which stunk, wouldn't work hardly at all, and my current, a 120V and Propane Dometic DM2672. It's a completely different experience. It's a great fridge. Uses almost nil electric on gas. Works as good or better...
  • Post in thread: Total Noob wants to run a mini fridge

    Maybe so, but you can most likely make up the small difference by simply buying a cheap power station (~$100) and 100 watt panel (~$60). Then you avoid the hassle of cobbling together an inverter, charge controller, battery, and ac charger and sourcing a box to mount it all in neatly. Any...
  • Post in thread: HQST MPPT 40amp Charge controller.

    I am curious what the boost voltage was set to. I have mine at 14.4
  • Post in thread: New tent /camping battery...

    I have a rebel 50ah battery myself. I keep it in an battery box with onboad fuses and 12V ports. Just out of curiosity, why would you want to mount solar panels to your tent? "In the future I will likely go with some tent mounted solar panels".
  • Post in thread: What size generator?

    I'm a little confused with this thread. The folks I know with very large 5th wheel RV's and other large TT's all seem to get by quite well with no more than <=4500 watt gennys when boondocking. (including PV, of course). With my own small (18ft) trailer, I run the 13K AC and micro with a 2200...
  • Post in thread: DC Fridge or AC fridge with inverter?

    Hmmm. Exactly how many 12volt portable fridges do you actually own at the present? I own both an ICECO and a bougeRV. I have had both for over a year now, and have had zero issues. The iceco has a german made compressor, and a 4 year warranty. The bougeRV has a 3 year warranty. Your car analogy...
  • Post in thread: What is the logic in a 2400W output solar generator… with a 1500Wh battery?

    The Bluetti AC180 goes on initial sale tomorrow, for $799. 1800 watt inverter, but only 1152wh battery. But it weighs 35lbs, so a very handy weight. I can see this being very useful for camping and around my farm for remote power tools.
  • Post in thread: Stock Tank Solar Power

    In western nebraska/South Dakota/eastern Wyo, Waterfowl hunters use exactly that to keep water open on a pond in the most severe conditions. There are ready made rigs to bubble or even floating circulating pumps. Gotta be the best solution to this problem.
  • Post in thread: Pickup Popup campers: roof mounted panels vs. Portable panels? What is your overland camping experience for best?

    Both, 2x100 watt on roof, powers house batts, 1.2Kilowatt folding panels 4x320watt for AC200.
  • Post in thread: Van Life - Sleeping Above / Near Batteries Inverter etc

    So, from what I have read/watched, the safety risks for lifepo4 are from cell puncture or short circuit. Is this true? Is out gassing almost nil, or could there be any possible perils from that? I'm guessing minimal. Lifepo4 batteries aren't known to spontaneously combust, are they? I haven't...
  • Post in thread: DC Fridge or AC fridge with inverter?

    But if you already have a simple 100 watt or better panel, and a battery? I paid $192 for my cheap Chinese 12volt fridge. Takes up very little space, and consumes ~130 Wh per 24 hours. So, for less then your choice, you get the convenience of a portable fridge that weighs less than 30lbs. It's...
  • Post in thread: HQST MPPT 40amp Charge controller.

    Something seems amiss here, the boost voltage for my two stand alone lifepo4 chargers is 14.4 and 14.6 respectively. Are you able to charge with a dedicated charger?
  • Post in thread: DC Fridge or AC fridge with inverter?

    I own and use an Iceco fridge similar to this model
  • Post in thread: How long can you (and your family) survive if the grid went down for an extended period?

    If you can actually hit things, a .22LR headshot will do nicely on a deer. Wouldn't attract attention, either.
  • Post in thread: Total Noob wants to run a mini fridge

    Amen. Sometimes, the simplest possible solution is the right solution. a small ecoflow of bluetti + 100 watt panel is way easier to deal with than a battery + inverter + charge controller. And actually cheaper. And small DC compressor "cooler" style fridges have advanced lots in the last 5...
  • Post in thread: Total Noob wants to run a mini fridge

    I dunno. Have you had a look on amazon lately? I don't see that much of a price difference between a dorm fridge and a small 12v compressor fridge. A little, but not that much.
  • Post in thread: HQST MPPT 40amp Charge controller.

  • Post in thread: Total Noob wants to run a mini fridge

    Just curious, have you ever owned an absorption fridge? If so, have you measured the power draw in AC mode? Yes, they are power hogs running on ac, everybody knows that. I did measure mine yesterday, just for fun. 325 watts. However, I can get 2 weeks on a 20lb propane bottle, with no electric...
  • Post in thread: What size generator?

    Alrighty. I thought you said 5K watts, not 3, but maybe I wasn't paying attention. On my off toad trailer, I have 200watts solar, + 600 portable in needed, 206Ah LifePo4 + 2000 watt inverter if needed. Obviously, I don't run the 13K AC off the batts, and rarely the micro. Water heater and...
  • Post in thread: DC Fridge or AC fridge with inverter?

    Ok, just attempting to come up with a standard set of rules. So, we should then place two ambient temperature gallon water jugs in the fridge at start, and we expect the fridge will also be at ambient temperature. Sound about right? Or, should the time-to-operating temperature a separate test...
  • Post in thread: EB3A "Overload" When Used as Uninterruptible Power Supply

    Well, at least so far, it's been a handy little unit. I have other, larger pps's , but the EB3A is just so convenient, and my only one with UPS. I hope they get the bugs worked out.
  • Post in thread: DC Fridge or AC fridge with inverter?

    Somebody said you could get 5 AC fridges for the price of an entry level DC fridge. This is the cheapest fridge I could find at Wally-world, maybe somewhere else is cheaper...
  • Post in thread: "Renewed" Bluetti units from MaxOak

    I bet you get it sooner. I use my eb70 lots camping, the inverter has enough power to run my single serve coffee maker, and I also use it to run a compressor DC fridge. I have over 400 watts of folding panels, so I can boondock almost indefinitely with the 100ah SOK house battery and the bluetti...
  • Post in thread: "Renewed" Bluetti units from MaxOak

    Maybe you should take a chill pill, and stop being triggered by a simple "look", Pal. You are the one who was triggered by a simple answer. Fridges are one of the most discussed and beat to death subjects around here. How about coffee makers? What brand of single serve coffee maker do you use...
  • Post in thread: EB3A "Overload" When Used as Uninterruptible Power Supply

    Nope, no bugs at all. Never had any serious issues with any Bluetti products yet.
  • Post in thread: DC Fridge or AC fridge with inverter?

    Please see my original post, and also a more recent one. I have been using both of my DC fridges extensively for the last year, as I have stated before. the argument that the compressor is cheap is compared to what? A $79 dorm fridge? really? My 50Ah rebel lifepo4 battery takes even less notice...
  • Post in thread: DC Fridge or AC fridge with inverter?

    As am I. 1 year going on 2, so far. Good luck!
  • Post in thread: DC Fridge or AC fridge with inverter?

    Please show us the make and model of your inverter, and how much you paid for it. That must be factored in., as well as the warranty. Please keep us posted as to how much you use it and the failure date. HaHa
  • Post in thread: Victron is Over-priced Eurotrash. Why would anybody buy Victron over an AiO?

    Question. If a person posting on this forum has a pecuniary interest in promoting a particular product, should that fact be disclosed to the forum at large?? Or, is it already??
  • Post in thread: DC Fridge or AC fridge with inverter?

    12V portable fridges aren't expensive at all: https://www.bougerv.com/collections/car-refrigerator/products/12v-portable-refrigerator-30-quart If set to cool just below 40f, you can consume as little as 135Wh/24 hours. A single 100 watt panel will give you almost unlimited power when used with...
  • Post in thread: "Renewed" Bluetti units from MaxOak

    I have had an EB70 for about the last 6 months. It's a good little unit, for what it is. I use it to run my compressor cooler fridges and it also has just enough inverter to run my travel single serve coffee maker. It will also run a small hairdryer that I have on low setting. My kids love the...
  • Post in thread: DC Fridge or AC fridge with inverter?

    Yes, indeed, it is foolish. It is a fact that companies employ people for the specific purpose of disparaging a competitor's product, to sew the FUD, as it were. It's pretty obvious with a lot of products. It's been a part of marketing practices for a long time, however unethical is really is...
  • Post in thread: Powering a small refer?

    What kind of steak is that? It looks like chuck roast to me. Anyways, my bougeRV 23q fridge uses exactly 38wh per 24hours cooling to below 40 degrees in 75 degree weather. When there is even a little bit of sun about during the day, even a small battery can keep me running indefinitely. Running...
  • Post in thread: HQST MPPT 40amp Charge controller.

    Thank you. I have had mine since march. As I said earlier, I haven't had any issues yet. Yep, I have noticed the rather short range for the bluetooth.
  • Post in thread: HQST MPPT 40amp Charge controller.

    In theory, the BMS should take care of the balancing. If it's a sealed case, that would be the only way. One cycle down to 0 shouldn't seriously damage the battery, the BMS should have a low voltage cutoff anyways. it sounds like you have something else going on. Is the battery covered by warranty?
  • Post in thread: To buy or to build

    I don't see anything on my list that is $800???? Look, I tried to be as conservative as possible with the estimated prices, just to avoid the niggling that you are doing right now. When the OP wrote about diy, he used an example of a 12v battery. A diy system is in any event, not even slightly...
  • Post in thread: DC Fridge or AC fridge with inverter?

    So, let's debunk the argument for a AC fridge, at least for grid down or camping. OnTheRoadAgain says he is using 300wh for 10 hours on a Jackery. (it isn't stated how this was measured, I have a Jackery too, they don't measure watt hours used, just percent power remaining) I use a kill-a-watt...
  • Post in thread: To buy or to build

    The AC200L is already 48 volts internally. You can add additional batteries at will. The OP was looking for a small system. A quality power station is a simple and easy solution to the smaller needs the OP spoke of. OP: "I want to power a cargo trailer (6x12) so the demands won't be great...
  • Post in thread: DC Fridge or AC fridge with inverter?
