    Small expansion to generation capability...

    Externet: To answer your question, you would have to provide a bit more info on your current system. But in general, it sounds like you don't want to mess with it, or risk screwing up something that is working fine. That being said, I might be in a similar position, and here are my current...

    Samlex now has a split-phase inverter charger

    This looks like a very capable inverter. I spent about 30 minutes looking at the extremely detailed manual, and did not see any mention of stacking. What did jump out at me is the very high DC input range at 68v, and that it is listed. Nice! Maybe Victron will take note, and get some of...

    High Voltage Inverter / MPPT Solar Charge Controller

    It is Tabuchi. Battery Hookup has typos they have never fixed. Very high quality inverters, and they can be bought for a LOT less than what BH is charging. There are a lot of them sitting in warehouses being neglected since Tabuchi shut down their San Jose office.

    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...

    Victron Multiplus II 2x120 - Too Loud?

    JC1409: Instead of the Multiplus 2, you could consider the older series units Multiplus or Quattro, which have a thicker case. It would cost more, but might not be as susceptible to noise transmitted through the case itself. Just speculating...no real world experience to back that statement...

    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...

    36v inverter for SAMSUNG 8S 28.8v 7.8ah 225wh w/ BMS

    The whole point of those packs is that they have a working BMS. If you are not able to parallel them up in sufficient quantity to meet your load demands, why even bother? Snoobler is right. The OP has 8 packs, so a couple hundred dollars total. Why spend much bigger money on an oddball...

    Security System for Off Grid Container(s) & Shed

    Get good insurance. Take lots of pictures, and store them somewhere safe. As a victim of a large burglary, I can tell you that next to nothing will stop a determined thief. Cordless Sawzalls, portable torches, hydraulic jacks for spreading jambs...the list goes on. Do what you can, but get...

    Offset Electric Boiler energy usage with batteries and solar?

    Mechdriver: I prefer chocolate/raisin/oatmeal...thank you. The electric boiler would be a big mistake. Two years ago, I swapped out one that my friend had running just to heat his work shop. His electric bills went down an average of $150/month when running that boiler. Here in the Midwest...

    ~100kwh for 24/7 off grid home

    Tanoshimini: How are your 16s cells faring? I'm still looking for the right solution for my prismatic cells, which if left unchanged would be 8s/16s. Also have some 12s I might want to modify to get that voltage up. I need to understand, and verify what happens with the voltage curve and...

    Offset Electric Boiler energy usage with batteries and solar?

    mechdriver: you suffer the same affliction that I tend to exhibit at times. You see a technology you like, and then want to find reasons to justify it. Nothing wrong with that, if it makes you happy, and you end up getting what you want as a result. I've done most of the things you are...

    16s Chevy Volt 64v battery BMS and Inverter.

    Snoobler: Did you finish up this battery, and if so, how is it working? I'm very interested in your thoughts on the subject of charging 16s to a lower voltage threshold. About a year or so ago I read a very detailed Samsung white paper on the topic of NMC batteries, but for the life of me I...

    Nope, they don't make these, or even assemble them. They just unload containers of them, shipped from China.

    Schneider xw pro 6848 not powering up with eg4 lithium battery

    Hedges: Would a heavier gauge of wire be better in this situation? Like 10g? Just asking out of curiosity.

    I need a new inverter

    Ken: What is your opinion of the Magnum? Do you like it? Quality? Noise level? Some people knock them because they have an old fashioned style transformer. I don't see this as a problem per se... I've talked to them on the phone a couple of times, and I got knowledgeable, friendly people...

    Planning a Home Standby System - Input Welcome!

    Shaun: Go to Harbor Freight and get yourself a nice AC/DC clamp meter, that will allow you to check these parameters. The Kill A Watt are great too. They are pretty decent units, and are very reasonably priced. I'm happy with mine. A lot of your numbers are high compared with what I've...

    Safe Grid Use of the 5000ES and transformer

    Hedges and High Tech Lab: Now you have done it...brought up the 2020 code. I've tried to do that recently regarding getting equipment installed an approved by my AHJ, and all I got was a bunch of unrelated comments and arguments from people who don't seem to grasp the implications. I won't do...

    Safe Grid Use of the 5000ES and transformer

    eabyrd: It seems you are correct. I don't see why there is so much resistance to the idea of a separate loads panel. They are easy to buy, install, etc. But the bigger issue is that this industry (like many others) is relying on influencers to promote their product, and sell them. Those...

    Too funny Steve! People are missing the point, or have misinterpreted some comments I have made. Or, I stated something in a not perfect manner. It isn't necessarily about what State you live in, it is about your AHJ. Our State of Confusion is still on 2017, or something like that. But...

    Hedges: The link I copied from another person on this forum talks specifically about detached structures providing power. The State official here made the comment to me that this closed one of the biggest loopholes in the older code. They did it by determining that if the energy is used in...

    You have to read all the posts, and pay attention to what was stated about NRTLs. Nationally recognized testing laboratories. If the testing isn't done by one of those, it doesn't count. Those certificates don't mean squat here in the USA. Will Prowse made a good point about his audience...

    LTO SCiB battery bank for off-grid

    AmpLee: Peter Perkins in Australia (?) is one of the guys who has done a lot of work on the Fit battery BMS. You can find him on the Insight forum. As I understand from Greentec, the Fits in the US were only leased. Greentec got all the batteries when they were scrapped out. I have some...

    Bud: There are 12v, and 24v 3000va Victron units that are UL approved. As far as I know, that is it. I would buy 5000va or 8000va units tomorrow if they were UL approved. Nothing 48v is UL listed. If you read on the Victron site, there are many mentions of them getting approval for their...

    Robby: I'm not talking about how the panels are mounted, but more about how the energy is distributed, and used. I don't care in the least if someone has panels laying against a wall, on the ground, etc. In fact, I considered buying an old mobile home frame to adapt into a back yard temporary...

    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...

    I strongly urge others to jump into this issue, and check it out. Then report back to the forum. I hope I'm wrong. I read a plethora of OSHA, NRTL, NEC, UL, Fire Code, etc regulations, and talked to a lot of code officials. Also, some companies like CED Greentech. The consensus was what I...

    Steve: Precisely stated! It drives me crazy that there is no reliable, easy way to determine exactly what can, or cannot be used. I've talked with the head inspector for our City, the State inspectors, the electrical governing board chairman, etc. The bottom line is that what we have to do...

    Sanity Check ~13kw System Build, Storage Requirements, Growatt 12kw?

    It doesn't help. They are supposedly compliant (they cannot get the spelling on the label correct, it seems) but that isn't the same as listed. If the jurisdiction requires listing, it won't fly. A very important point is to find out what year NEC is adopted in your area. The new 2020 code...
