  • Post in thread: EG4 6000xp EPS overload

    The pop up hints do not change when you have parallel inverters so in effect they LIED to you. My discharge max says it cant go over 110, but I have it at 125? Hmmm LIES!!!
  • Post in thread: JK BMS - Does It Recalculate Capacity?

    That was such an awesome and well thought out answer.
  • Post in thread: Cell prices coming down

    Sounds bloody awesome!

    Its Fine!
  • Post in thread: Sudden drop to 0% in SOC with EG4 6500Ex + EG4 LLv2

    With your usage patter,If these batteries were not turned off routinely, that would explain everything. The Battery management system consumes power and I doubt its included in the SOC value displayed.
  • Post in thread: 6000XP Wiring and questions

    Inverter based dryer? If not, some "low power" drying modes do use less amps. Mine is not like that.... Hut tub?? haha I wouldnt feel lucky if I were you. Heat is heat no matter how you slice it. What breaker is it on? That will be your best clue! Put a smaller heater in there? I just put...
  • Post in thread: 280Ah cells with low capacity - can I still use them?

    I support all the conclusions presented. One BMS for each group is absolutely ideal, but I wouldnt consider it mandatory. It would be tremendous insight into how the orphan pack is doing, spot trouble much easier (abnormal cell deviation would be masked if 2 in parallel) , and allow twice the...
  • Post in thread: Wireways. Where to buy?

    I want a 6x6 x 5 foot wireway. I've seen some but $400 for a square metal tube seems unfair. What does everyone do?
  • Post in thread: Happened again, DIY battery fire

    excellent point.
  • Post in thread: Is it common to lose 10 percent to your shunt compared to AIO input?

    That act never ends. :)

    I got this one and it is nice. never used a FLIR tho https://www.amazon.com/gp/product/B0B7LMB22Q/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
  • Post in thread: Weird issue with 6000XP 🤷‍♂️

    looks good at 10 amps. Give it some time. Did you mean over voltage protection?? If it says over current protection that would be a different issue.
  • Post in thread: Solar has been hijacked/co opted. A wakeup?

    The future sure is bright. Oh wait. I guess it might not be illuminated. Can it be bright and not illuminated at the same time? Oh for heavens sake...
  • Post in thread: EG4 6000xp with JK Inverter BMS

    Having one BMS that is at least close to the parallel bank would be miles better than what I am doing. All I want to do is leave enough space in the battery for the next days sun. I hate losing watts because of full batteries. I will definitely be looking into that project.
  • Post in thread: Am i buying a decent hybrid and is it legitimate advice needed,

    I really enjoyed all of this.
  • Post in thread: Abusing free nights electricity plan with batteries

    You are one of the good ones!
  • Post in thread: Polyurethane foam to fill DIY battery case voids?

    Nice!
  • Post in thread: Blosted lifepo4cells

    I am sorry and sad that this happened to you. What is that low cell about? It isnt circled in the photo. 3.26- 3.0 is quite the spread! That could possibly be one at 10% and one at 60%.
  • Post in thread: Polyurethane foam to fill DIY battery case voids?

    Ever tried burning that foam?
  • Post in thread: Solar panels are producing high voltage at night

    I was only getting 400 watts overnight.. Not enough!
  • Post in thread: 1st off-grid adventure — need charge controller advice

    I would say that is too close. It is certainly not worth it given you probably wont lose anything besides another run of 10 awg Smart plan. Because you will hit it on a cold mid morning and every single time your batteries are full with the sun out. Over voltage is the WORST thing you can do...
  • Post in thread: wzrelb pure sine wave 5000w 24v power inverte

    Using a Kilowatt meter like seneysolar mentioned for the inverter output would be a great step. You also could use a meter on your battery before the inverter. A Victron Smartshunt would be ideal and a wonderful long term investment for measuring exactly what is going into the battery and out...
  • Post in thread: EG4 18kpv Update

    So simply powering off SA would be fine here? I installed firmware twice for my 6000xp with no apparent problems?
  • Post in thread: New 6000XP working great, except for dongle communications. The blinking led is driving me crazy.

    This is true but a lot of the new routers only have one SSID and decide what feed to give a device. My guess is the OP is using a 2.4/5ghz bridged SSID and the dongle cant grab the 2.4 because it cant see it.
  • Post in thread: 6000xp reading interpretation?

    Nope.
  • Post in thread: EG4 6000xp manual is pretty lacking.... I could use some help.

    The manual references "Working Modes" But I have not found any documentation on how to change or test these settings. Searching the pdf manual for "Bypass mode" I get nothing that will help me change to it... It appears I am stuck in off grid mode and this is not ideal. I am not looking to...

    Busbar, lug, washer, lock washer, bolt.
  • Post in thread: EG4 - 6000XP

    I had this happen as well, I believe it was a requested feature. I for one am glad it stopped auto cycling,
  • Post in thread: 6000XP Cooling Fan Observations

    I guess I should say that Im pulling in 3300 watts into each PV input with peaks nearing 4000. So Im using it pretty close to its fullest. I know when clouds are rolling thru from the sound in my kitchen and the 6000xp is in my basement. :)
  • Post in thread: Connection over cable not possible JK BMS

    Yup, this is what happens to me with my 6000xp and is my biggest complaint... I didnt know what was causing that. So far this happens with the JK inverter BMS and the victron shunt mod that converts it into a fake BMS
  • Post in thread: EG4 6000XP Monitoring app, lacking pFromGrid Data?

    I love mine. Bought last Nov. Purchased a second one a week ago!
  • Post in thread: 6000XP won't start charge with 188VDC

    Should start at 145 or so.
  • Post in thread: #%*?£€ Battery x 2 lithium charge issue

    Are panels wired in parallel? What is your PV line voltage? If you have them wired in parallel they might not have enough voltage to charge a 24v battery. What is your battery voltage? Are they in parallel? Bulk means its trying to charge. I recommend getting the Victron bluetooth adapter so...
  • Post in thread: adding a second battery bank to my EG4 6000xp- any major issues

    By the way, by similar voltage I really mean as close as possible. Your BMS will trip out if you dont.
  • Post in thread: Hello Everyone

    What would you do differently?
  • Post in thread: 2 parallel 6000XPs pseudo schematic - Is my wiring right?

    Looks good to me! But of course wait for a couple more people to chime in. Nice detailed diagram! It would help if you gave a link to your buss bars. Their is no spec listed and they are pretty important
  • Post in thread: EG4 6000 XP general questions

    Thanks for the info!
  • Post in thread: 6000XP transfer time

    Perhaps it is in bypass mode when that switch is off? AKA grid/ no emergency power. I do understand the confusion.
  • Post in thread: Future of DIY LiFePO4 looks bleak…

    I sure was a loser buying Renogy 48v 50Ah batteries for $1300 each... I bought 8 in 2021 Now they have been as low as $759 .32/w
  • Post in thread: DIY Battery via Smart shunt to inverter integration (Solis etc)

    I am not sure. I Calibrated to hit 99% at 3.65/cell and now am charging to 3.48. Not an issue really. I know turning off the pylon switch helped but I remember it triggering again. Let me know what you figure out.
  • Post in thread: DIY Battery via Smart shunt to inverter integration (Solis etc)

    I have not yet, but I plan too.
  • Post in thread: 3 years later...batteries swelling

    Agreed.
  • Post in thread: 6000XP won't start charge with 188VDC

    Any chance that you improperly set your charge voltage?
  • Post in thread: Lifepo4 cell compression, for a stationary AND low capacity set up, useful or useless ?

    I love when we talk about compression/ no compression. That convo has never been settled, yet here we are talking about compression that isnt demonstratively perfectly equal. Compression can kiss mine.... If I need to replace my batteries in 7 years vs 12 Im ok with that. Sure beats bashing...

    This is interesting. @EG4_Jared
  • Post in thread: Acceptable temperature of wires/lugs during normal operation

    Ok sorry to be insensitive but.....Watts means nothing with out voltage. Volts X Amps = Watts. Watts/voltage= Amps What voltage is your battery?
  • Post in thread: Eighteen 200 watt Renogy solar panels shot to heck?

    Im in Wisconsin in an unusually "not as cold" winter. My panels have been at about 85 percent since the 3rd week of feb. My angle is at 42 degrees My 3600 watt array is getting 15-21 kw on a typical good day. I think my angle is actually perfect for where the sun is right now and less ideal in...
  • Post in thread: Acceptable temperature of wires/lugs during normal operation

    Yup, Fuses by nature get warm. I think mine at a 80 amp draw gets to about 130F Mine is an ANL fuse. They are notoriously warm. If you are SURE that the fuse lug connections are good, and there are NO washers between the lug and the fuse, You are fine. No drilling lugs either, NO bright...
  • Post in thread: 6000 xp bad start

    no, you need an Ethernet dongle
  • Post in thread: BMS active balancer becomes unbalancer as cells age

    I am surprised to hear of an EVE 304 having a problem at the 2 year mark. What typical and max currents were you pulling? I understand this problem. I have seen this behavior for the last decade. It is not unique to LiFePo4, it is every chemistry including lead acid , tho you just dont notice...
