    Rumble?? You might google around about that site. It's pure toxicity.
  • Post in thread: This could effect all solar projects seriously

    Censorship is not equal to truth. Just about every forum has censorship, this one included, yet you'll find plenty of great/true information here. So, you can easily see how censorship is not the reference for truth, but why wouldn't someone know that already? That's a big red flag. What you're...
  • Post in thread: Please Needing Help Quick

    Back on page three I posted a link to a document from the product info page. The Predator 4375 is not an inverter generator. When it stops charging, does the grid icon disappear? NOTE: Inverter-type generators are strongly recommended as they have cleaner output than conventional generators. If...
  • Post in thread: Please Needing Help Quick

    I'd be curious to know what happens with a different generator, ideally an inverter generator.
  • Post in thread: decent LED lights

    If links weren't allowed, that not-quite-a-link you posted would still be considered a link lol. The way I read it, they're trying to stop people from spamming sales of products that they have a direct/indirect interest in, probably because it creates a lower standard of information on a site...

    I might swap "demand" for "politely ask", but sure why not, what would be a reason not to make a simple inquiry with the manufacturer?

    I'd get the Weize for a budget RV battery.
  • Post in thread: My first solar project

    So 30w at 24hrs over two days is 1440wh. If you get lots of sun, you could round down to a 12v 100ah battery, but when it comes to the life and death of little critters, you probably want to round up to 2kwh. Divide by 5hrs of sun per day and you'd need 400w of solar panels. If you're looking...
  • Post in thread: I want to power my desktop

    That's cool you're using a low power computer. It's the best things you can do when it comes to building a solar kit, is to reduce your needs first. I'd round up to 100 watts for the computer and monitor, but how many hours does it need to run for? If it gets dark early, say 5pm, and you wanted...
  • Post in thread: Is ventilation needed.

    It's just a reference for you/me/him/anyone as a starting point to extrapolate running temps depending on various factors. If it's 100F outside and you have thousands of watts running through a small steel enclosure baking in the sun, you could easily see 180-200F+ and be into runaway meltdown...

    Musk himself is a loudmouth narcissist seeking attention on the internet. The world doesn't really need anymore of those. Tesla seems pretty cool. I wish they'd make something closer to a Civic than a Crown Vic though. At some point we should embrace efficiency, as opposed to the current...

  • Post in thread: 12 Volt 400 watt system per Will Prowse

    For folks that live in the west/southwest, consider an evaporative cooler. We just bought a Bonaire 5900 for the house and it's been pretty amazing, even on the lowest setting where it's only pulling about 220w.
  • Post in thread: I want to power my desktop

    Hmm, maybe not? I searched what was on the label, "Lenovo Thinkcentre M92p" and found this: https://www.lenovo.com/gb/en/desktops/thinkcentre/m-series-tiny/m92p/ Says there's a 65w adapter, but perhaps there are variants of the M92p?

    Looks like it's $500 now.
  • Post in thread: Another inverter question 24v input , 240 volt split phase

    One nice benefit of using two units for split phase is if one of them has issues, you can still get by with one unit.
  • Post in thread: LFP for EV's projected to be less than $56 per kWh within 6 months

    Battery Clearing House is doing 50% off all LifePo4 through the rest of this month and they have 95% capacity new 50ah prismatic cells for $12, which works out to 6.25 cells per kwh, which works out to $75, or $37.50 before shipping ($250min order).

    The item on the left is the shunt.

    It's a transfer switch: https://www.amazon.com/MOES-Controller-Automatic-Transfer-Switch/dp/B07F12RDZ2 Will has a video testing that model. Seems like it's not bad for the money.
  • Post in thread: Is ventilation needed.

    I'm currently working on a solar trailer, so I've been looking at the defunct DC Solar trailers to see how they dealt with temps. They used uninsulated steel NEMA enclosures, most of them packed tight! Check out the images in the ads...
  • Post in thread: DIY solar generator trailer

    I think it looks pretty sweet!
  • Post in thread: I want to power my desktop

    Well, nothing wrong with reading the tag, but it looks like there are bigger models and I see the numbers now on the label. Looks like it's 8a at 120v, so.....yikes. I'd get a different computer. It would save quite a bit of money over trying to build a solar kit to power it.
  • Post in thread: All-in-One Inverter plus SCC Questions

    Interested to hear about this too, since some of the MPP Solar AIO's are a tremendous value, if not for the wimpy PV input and charge rate.
  • Post in thread: What products would you use?

    6 watts for 10 hours is 60 watt hours. We love the lifepo4 batteries, but you can't let them get to freezing. If that's not a problem, then you can get a 12v 10ah lifepo4 battery for cheap and that would give you 120 watt hours, so you have an extra day of autonomy, should you need it. If...

    Yep those, definitely not plug-and-play grade, some sweat required. But! When you need that rock bottom price point and are willing to trade effort to get it, it's always nice to have the option. They look to be these: https://eu.nkon.nl/ace-battery-26148129-fe-50-lifepo4-3-2v-50ah.html And...
  • Post in thread: Calculate Battery Amp Hours

    51.2v? But, technically we don't know the chemistry yet.
  • Post in thread: 12 volt or 24 volt

    You could stick with 12v if your use is low. If it's just a few lights and a laptop and a refrigerated cooler, then there's maybe no real reason to move up.
  • Post in thread: Assembling my 2000w 24v system.

    They would probably say something like, "WHAT R U DOING?!?" lol.
  • Post in thread: Pushing the charge controller specs

    Well that's odd, it looks like there are two different specs on Amazon, an 80a/150v for $335.59 and an 80a/200v with some accessories for $428.99. I ordered the Hybrid LV2424 from Watts247 yesterday, but am not counting out the EPever, because I'll have an extra panel for another project...
  • Post in thread: Mid-design Overwhelm Questions

    Right on, that doesn't sound bad at all. I like the Growatt and don't know much about the MPP. Were you looking at the 5k plus transformer to get the higher PV voltage than going with the 6k with built-in xfmr?
  • Post in thread: 12 volt or 24 volt

    I wouldn't feel a pressing need to go to 24v for that. As acdoc mentioned, the DC side at up to 200a is no joke. You'll want 4/0 wire, which isn't all that bad at $125 for 10ft of red and 10ft of black, then figure another $75 for proper lugs and crimper. Realistically, you won't be seeing 200a...

    You must be new to your area? I'm not nearly as remote as Northern Alberta, but when we moved rural, my environment helped me readjust my expectations pretty quick.

  • Post in thread: 12 volt or 24 volt

    Yeah I'm not seeing the need. You can certainly do it if you're wanting to, because you'd have better expandability at 24v, but I'm not sure I would. There's something to be said for 12v systems, like being able to get by using local parts from the auto parts store or home depot in a pinch.

  • Post in thread: Sizing Parts For a Solar Generator

    I wouldn't use a charger through a charger. I made a few small battery generators and just have a separate XT60 harness tied directly to the battery for charging. I'd think it's fine to use a dc power supply for charging through the solar input though. Not sure on the fuse size, but those cells...

  • Post in thread: Need Help with Everything Solar

    Folks always like to work in reverse, starting with what you want to power and go from there. All the basic formulas and general thought processes are designed around that. Even though you can design around the panels, or design around a budget and let the power be what it will be, I still think...

  • Post in thread: Hankzor JK BMS with screen and power button

    I hear ya, just can't really sit idle on the project for up to three weeks. I wanted the JK, but ended up ordering the JBD from Current Connected and had a tracking number in less than an hour and they're just one state over. Tough to beat. I may order a JK for another project that's less pressing.
  • Post in thread: Charging system constraint?

    So you're estimating, the 5kw panels are outputting 3kw over five hours, and you want to know if it's possible to *not* have your batteries fully charged in that amount of time, assuming that you're not drawing from the system in the interim and also assuming the batteries are fully discharged...
  • Post in thread: System size for 220 volt well pump.

    Much of Florida has such a high water table that you can get away with the little above ground pump. You could go deep if you needed a huge draw down for ag purposes and had a slow recharge time, but really a 1.5hp isn't very big and probably could never draw down faster than 485ft can recharge...
  • Post in thread: Charge Controllers, help with math ?‍♂️

    With the five batteries wired in parallel, that would be a 250a charge rate, but you always wants to back it down a bit from max charge rates, plus you're getting into some big wires. I dunno about what the dealer is saying, something is wrong in there somewhere. Either he's not very well...
  • Post in thread: Pushing the charge controller specs

    I ordered five of the 445w version of these from SanTan Solar, which I had planned to use with this, but now they're out of stock until October, which isn't going to help much for summer fire outages, plus a budget change is forcing a 24v setup, so I need to put something together sooner, even...
  • Post in thread: Need Help with Everything Solar

    Never said that "defining a problem someone wants to solve first" is working in the reverse. That's such incredibly broad language. When people think about where electricity comes from, from the power plant all the way to the vacuum cleaner, the very last item is the vacuum cleaner. But, you...
  • Post in thread: Planning Ambulance RV solar sys. Need critique. please

    Was referring to the DC-DC converter for using a 24v battery to power your 12v devices. You connect your 24v battery to it and then power your 12v devices from it. For a DC charger, that's just done with your solar charge controller, so your solar panels connect to your charge controller, then...
