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...
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...
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...
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...
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...
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.
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...
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...
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...
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.
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...
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...
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...
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!
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
