  • Post in thread: Will please answer this question regarding your recent video...

    Bud: I have no idea how the 2020 code, or our AHJ would treat those units. Many people here came up with many different scenarios, most of which I cannot answer. I will restate this one more time, and it might clear up some of the confusion: Our Midwest state adopted the 2020 NEC. It has...
  • Post in thread: Doing things a bit different for simplicity (14ft box truck) 24v setup.

    jjcheramie1022: While you are in the planning/learning stage (which never ends, by the way!) take a look at Battery Hookup out in PA as a source for batteries. Many people, such as OGITC build their own packs from 18650 cells, which is great. You can also go the route of surplus automotive...
  • Post in thread: A newbie, a beautiful old off grid cabin, COLD wintertime temps and needing some SOLAR power

    Hopitrout: Hey, beautiful site! I'm worried that on this forum people might think I'm pushing hot water panels, which is not the case. But, if that was my cabin, and I did not want to insulate the upstairs, I'd be looking at building a passive heat storage system, and possibly put in some hot...
  • Post in thread: Building a 72KwH battery system, help understanding these Li-ion modules.

    You will get many opinions on this forum to consider before making an informed choice. It is wise to do what you are doing right now...ask questions. Just a couple of observations to add to the list: There is nothing wrong with Battery Hookup. Like you said, they don't hide what they are...
  • Post in thread: BMS on parallel battery pack

    Gagile: First, lead acid, or lithium for your boat? If lithium, you should have a BMS. Second, you can put a BMS on batteries in parallel. The BMS will have to be tailored to how many cells you have. Third: Series connection is to increase voltage. IE (4) 12v in series is 48 volt. Fourth...
  • Post in thread: Another recommendation needed

    TexasSun: First thing to do is check with the AHJ (who has authority there?) and find out if you need UL listed. If so, your choices will be greatly reduced. If not, I'd second Victron. The new Phocos model looks nice, and it will be UL approved.
  • Post in thread: DJ Rack power tower conversion

    I cannot comment on the load bearing capacity of those batteries, but would suggest a change or two. Since you have that nice rack, why not use it like it is designed for? Put some shselves in, and space the batteries out to make better use of the volume. That will make it cleaner, and allow...
  • Post in thread: Are there any high voltage (300-400VDC) mppt controllers?

    ponobill could you make a SolarEdge work in this scenario? They purchased Kokam and are bring one of those packs to market, at about $6k for a kw pack, high voltage. I wonder if some clever person here can make another high voltage battery work with the SolarEdge inverters? Also, just check...
  • Post in thread: Sol-Ark 12K Parallel Stacking setup.

    I second the recommendations by FilterGuy. With the distance involved, I'd want to ground that racking where it is installed. I'm looking at a smaller version of your project (about half sized) and the same issue is coming up. By an interesting coincidence, the utility is burying all the...
  • Post in thread: Remote Cabin NH (long post)

    Erik: I'd just get a bigger tank to add to your current setup, which is a great way to go. In cases where I am not using any ferrous metals in the main system, I tend to go with a big air pressure tank, and plumb it to an inexpensive heat exchanger so it forms its own loop.
  • Post in thread: Transformer disconnect question for 230v to 115v

    We have a couple Square D type SK, Class 9070 transformer disconnects NIB. They are 230/460 primary, 115 secondary. 1000 va, 50/60 hz. Paid next to nothing for them. Watched a couple videos on setting these up, but am thinking that it is the older 230v that people used to call our NA...
  • Post in thread: Newbie to solar water heating need advice.

    Silver88: Look up "solar hot water controller". There are many units made for controlling exactly what you want to do. They range from about $150 up to who knows how much. Most of them are made in China, regardless of the name on them. If you google a solar hot water panel company, they...
  • Post in thread: Multiple Victron Phoenix 230v off Victron 100a Auto-Transformer?

    Victron supports running their 230v Euro inverters such as Multiplus or Quattro off their autotransformer to derive a neutral to utilize them in the United States. Is there any reason you couldn't run several smaller 230v Euro units off the same autotransformer? Assuming the total VA would not...
  • Post in thread: DEYE Inverter UL Listed available in US

    Do the Seplos work with NMC, and other lithium chemistries? I looked at importing some of their batteries last year, but it seemed they were mostly (if not totally) foucsed on LiPO. Thanks!
  • Post in thread: GSL/DEYE/SOL-ARK??

    Make sure they have the approvals you need for your jurisdiction. That may not matter in your location.
  • Post in thread: Panels on a retaining wall?

    Hope this is in the right part of the forum. Has anyone mounted a solar array to a large retaining wall? Our is the type with the super heavy poured concrete blocks that vary from 3+ tons each to .4 ton each. My thought is to fab up some triangles out of aluminum, and use heavy expansion...
  • Post in thread: RV Remodel: 28KWh LiFePO4 + 3KW Solar + 2 Quattro 48/5000 Split Phase

    CharlesK: Interesting project you have there. I'm considering something similar myself, since I have the opportunity to get an older RV from a good friend. I do want to make a comment or two on inverter mini splits. I'm not that familiar with LG, but am very familiar with Daikin, Fujitsu and...
  • Post in thread: Sunny Island 6048 time controlled operation

    MurphyGuy: Don't want to hijack this thread, but could that same principle be used to start up and use a phase inverter off grid?
  • Post in thread: Outback Mojave inverter

    Ampster: Cut and pasted..... The Mojave™ platform combines the latest power electronics and control technology with the old-school muscle and practical features that define OutBack Power™. The Mojave inverter continues the impressive legacy of robust off-grid and grid-hybrid performance for...
  • Post in thread: best brands of inverters? best bank for the buck?

    I'd say you pretty much nailed it. Point 1: in same order you listed them, manufactured in India, Mexico, India, China and soon to be USA, Germany, China. Point 2a pretty much all China. Point 2b pretty much all China Soon to be added to US availability Tier 1 when they get UL listing...
  • Post in thread: Workshop installation - 2KW solar, MPP LV2424

    Evertb1: The US is great in some regards, but so far behind much of the world when it comes to policies. Here, it comes down to profit above all else. For example, we are the only major country that allows for medical/drug advertising on TV. And for some reason, we have the highest...
  • Post in thread: Panels on a retaining wall?

    Wellbuilt: more good ideas..thanks! I have a whole bunch of large anchors that I picked up for next to nothing, but the sleeve is only about 1". I have them from 3" up to about 6" long. Good quality, American made believe it or not. I like the idea of using epoxy. Been thinking about...
  • Post in thread: Shed/office flooring

    Rednecktek: I realize that. I've built a lot of homes in my time. After reading the first comments, which centered around jacking up the structure, or actually trying to help him cobble something in, I thought it might be easier for the OP to set his blade at the depth of the flooring, and cut...
  • Post in thread: Outback Mojave inverter

    Hedges: Yes, Midnite bought a whole bunch of units at the auction. If you look on their site, there is a listing of all the multitudinous offerings. You can (in some cases) substitute a bigger charge controller. I have read, but cannot personally attest to a comment that the charge...
  • Post in thread: Should have known living in a forest would cause problems

    Wellbuilt: may I ask what area you are in? We have interest in trying to find a spot up around Marquettte, Houghton/Hancock, etc.
  • Post in thread: Outback Mojave inverter

    Ampster: I still like the Skybox, and would seriously consider buying one if I knew for a fact it was not going to be cancelled.
  • Post in thread: What is a good base to set my batteries on outside, at the back of my house?

    I would not store any batteries outside, especially if they will be exposed to freeze cycles, or intense heat. If they must be outdoors, they should be in an enclosed battery box that has some provision to keep them warm. If indoors, possibly venting them. Don't locate your batteries directly...
  • Post in thread: Electric water heater with timer and thermostatic mixing valve

    Just a couple of comments to add to this old thread: Here in the Midwest, we have a lot of limestone, and very hard water. That limes up water heaters over time. We do 2 stage filtering of all water coming in the house, except for toilets, and outside spigots. I do run toilets through a...
  • Post in thread: Hybrid Inverter sizing advice

    I would not go that route. Buy the more efficient units made in 208/240, and power them accordingly. Personally, I would not try this with a 3k unit, I'd go at least 5k, there isn't that much difference in price. Try to buy an inverter that has split phase natively so you don't need an...
