  • Post in thread: Signature Solar EG4 200ah (24 volt) problems

    For what it is worth, the firmware upgrade did prevent the total shutdown of my EG4 Lifepower4 battery when starting the air conditioner. But it still would not start it on that Lifepower4 battery. I swapped in my EG4-LL, which is practically the same battery with a different BMS, and starts...
  • Post in thread: Getting more than 1500w out of an EG4 3000w and a single Lifepower4 48v

    Well, this was a particularly spirited string of problem solving I enjoyed very much. Any predictions on whether mine will work without a Micro Air.
  • Post in thread: Signature Solar EG4 200ah (24 volt) problems

    Boondocked with my 24 v EG4 LifePower4 pulling 100 amps continuously, no problem, via a waffle iron, hot plate, fans and lights and such this morning, using a 3,000 watt Giandel inverter. It all ran beautifully, including my Keurig which draws 58 amps. Cells well balanced. Still want to do...
  • Post in thread: Morningstar Controller Webinars and Resources

    Yeah, my two MS controllers are really solid and have been for years. No noise, perfect operation, easily customized, networked, and the software is surprisingly powerful when you spend time to figure it out. But you're right, not terribly dumbed down. More "industrial solid". IMHO
  • Post in thread: Can lithium battery pack be this cheap.

    I went so far as to see they were offering free shipping. But there was very limited information like where they ship from or delivery time frame. So, who is going to bravely step up and be the sacrificial penguin here?
  • Post in thread: Mixing Lead and LiFePO4

    I've got it going at my off grid cabin and it works very well. When the lithium fills up, it disconnects the batteries, and my chargers (solar and wind) continue to top off my lead. When done the voltages go down and it reconnects them. I have found a lot of advantages.
  • Post in thread: Mixing Lead and LiFePO4

    I think of a BMS as a device designed to shut everything down if certain dangerous events happen to a cell or cells. The BBMS shuts off charging too, but not necessarily only on those same dangerous events, and with more control and an eye on optimal charging of the bank. I've read many...
  • Post in thread: Signature Solar EG4 200ah (24 volt) problems

    I just ordered the cable tonight myself. I must have missed the need for a different cable than what I normally use to read my battery on my laptop. When I tried to update I got an error unable to read the boot file. So I'll wait. Wish I knew the particulars. For example, did it change the...
  • Post in thread: Mixing Lead and LiFePO4

    Good points. In my case I already had the LA I wanted to keep to preserve my investment in it, increase overall capacity and performance by adding lithium, and as mentioned I have an alternator attached (wind turbine) that I want it to stay connected all of the time to a load (like any...
  • Post in thread: Unsuccessful wind turbine story

    Well, it's true the physics are what they are. My experience with small wind is that its overstated to say it doesn't work given a proper location with the right setup and expectations in line with reality. Mine is running fine, it benefits my system significantly when needed, and has been...
  • Post in thread: Mixing Lead and LiFePO4

    I understand you think I haven't thought a move beyond the immediate, and that a superior chess player (which I'm obviously not) could look ahead and see what is faulty with my system. But while it seems to be obvious to you, I'm not aware, technically, what is wrong? Instead of educating about...
  • Post in thread: DIY 24-volt 560Ah LiFePO4 battery (272x2=544Ah) with Electrodacus SBMS0 and Electrodacus DSSR20

    I was in South Dakota ice fishing the day you wrote this. It was -30 the night we spent on the lake in an ice castle (like a camper with holes in the floor to fish through). Coldest I've ever been in. If that light bulb kept them warm enough during that cold streak, it passes my test!
  • Post in thread: reliable off-grid internet for monitoring - what are you using?

    Peplink MAX BR-1 mobile works perfectly for me. I have it running off my battery directly (using small $10 buck converter) rather than through my inverter so it never shuts down. I use a Verizon sim card in it tied to my family account, so $20 per month is what it costs. The router allows me...
  • Post in thread: Mixing Lead and LiFePO4

    Appreciate what you're saying regarding capacity and space to store batteries. In my case, I already had the lead in my cabin's garage and some space for a bit of Lifepo4 was not hard to come by. I suppose if I were trying to increase capacity all within the same space it would not fit, adding...
  • Post in thread: Unsuccessful wind turbine story

    Nice tall tower at 70 feet. If that is sufficiently higher than the trees which are within a couple hundred feet of it you could be up in a range where there might be wind worth harvesting. The tower on a deal like that is the most difficult part, and often what people skimp on, resulting in no...
  • Post in thread: Mixing Lead and LiFePO4

    So, I think we all know what the Puekert effect is, and I'm going to assume you meant that in a joking manner. But your statement simply begs the question. I'm waiting for your explanation as to how this manifests as problematic in a mixed system. Can you please enlighten us?
  • Post in thread: Signature Solar EG4 200ah (24 volt) problems

    On the video it appears they have that error once on the screen, if I'm not mistaken. Then it reads the boot info. In comments to the video one person writes about changing the order of wires to connect. Not sure whether that was with the other cable? Looking forward to information from your...
  • Post in thread: Mixing Lead and LiFePO4

    The BBMS doesn't primarily use voltage to disconnect (although it has a max voltage to disconnect for safety). Instead, it runs a counter as part of the BBMS using current, time, voltage, etc. to know what's in the battery. I have it set to disconnect when my lithium is at 95%. My lithium...
  • Post in thread: Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    You might want to double check that Seplos price. It's not $400. My quote delivered to US w BMS and whole kit is more than double that.

  • Post in thread: Favorite 24v SCC for small system?

    Look at Morningstar. Great controller.
  • Post in thread: Quality "small" MPPT charge controller

    Those Morningstar controllers last years. I've got both a 60amp mppt and the 45amp pwm. The larger one has Ethernet ip native as well as the usual Modbus type serial connections. The other has an adapter for the Ethernet. So I run a simple network. I used an old netbook to program both and...
  • Post in thread: Vote early! 60amp scc vs 80amp - and - EPever vs Outback ? need your opinions.

    Ten years. Yeah, the Morningstar's are solid as a tank. No moving parts to fail. Silent. Programmable, networked.
  • Post in thread: FS: Morningstar TriStar TS-60 Charge Controller

    Assuming this sold in the past year?
  • Post in thread: Can lithium battery pack be this cheap.

    Fascinating sleuthing. Thanks for the info.
  • Post in thread: Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Yes, that's great, thanks for the info. Even with some discount you might've got, mine seems likely in error.
  • Post in thread: Getting more than 1500w out of an EG4 3000w and a single Lifepower4 48v

    Ha! Well, I may end up with a Micro Air! Others?
  • Post in thread: Hybrid lithium and lead?

    In response to the OP's question, I have been watching the hybrid developments and in addition to the people on this forum who have been doing it and the video you posted, you can find others who have been working out the hybrid LFP and LA systems for awhile. See: This is an interesting 2016...
  • Post in thread: Mixing Lead and LiFePO4

    Here is an interesting 2016 academic article modeling the hybrid LFP and LA battery in a remote medical clinic: https://juser.fz-juelich.de/record/829025/files/PE_070_Christiane.pdf Here is a commercial product combining chemistries...
