  • Post in thread: Future of DIY LiFePO4 looks bleak…

    I totally understand your point. I remember buying my first ever CD burner computer drive in 98? perhaps. 1X speed at $350 and if you used the mouse more that a couple times it would ruin the disc. It was indeed terrible. As far as the renogy batteries, I am a lot more salty about being...
  • Post in thread: Weird issue with 6000XP 🤷‍♂️

    Are you speaking of just SOC not matching or cell voltage? Soc should be close but I have seen 5-10% difference in mine sometimes
  • Post in thread: Thanks,Dad, For Teaching Me to DIY Stuff

    No, but I was a step child for 98% of my life.
  • Post in thread: Renogy 1 M1 Review: Why Renogy Sucks

    This is the same problem i had. it was never fixed. THEY LIED
  • Post in thread: 6000xp with a condenser load?

    Umm if your condensor has a 50 amp breaker it may pull 42 amps constantly. That would be 10,000 watts at 240v. That isnt doable
  • Post in thread: Panel Cleaning!!

    That is so true!! If my ground mount wasnt next to my garden I wouldnt clean them. I just happen to have a hose in my hand so why not.

    Better run out and get some toilet paper!
  • Post in thread: Scratching my head wondering why the solar isn't keeping up.

    This is basically my setup :) I like it for preparedness more than usefulness.
  • Post in thread: 1 48V 100AH battery to 1 EG4 6000XP Inverter

    I would. BUT I would keep max loads to around 2000 watts and charge no more that 1500 watts. You can set charge and discharge limits in the 6000xp so it is totally doable.
  • Post in thread: Luyuan battery case

    You are supposed to double side tape your bms to a yellow insulator board that you might have found on those 4 screw standoffs. I'm not kidding. I saw a video on jk bms with this case. I bought the same one. Isn't it sad?
  • Post in thread: 100% SOC batteries taking current, randomly

    This is my bet. BANG on man.
  • Post in thread: 6000 XP problem with Grid only

    There is NO Utility/SUB/SBU/SOL choice.
  • Post in thread: Totally confused Noob

    Now you're thinking!
  • Post in thread: Lifepo4 voltage drop recently

    Here is a nice chart for reference. Keep in mind if you are charging or discharging the chart is lass accurate the more you are charging or discharging. Also, I dont believe anyone has mentioned voltage settling. You would charge to 14.4 until the current drops to basically nothing. Your...
  • Post in thread: EG4 18kpv quick charge not working

    I tested that on my own system when I saw that. Quick charge works over here with AC charge off. Ac charge is for SOC. voltage and scheduled charging. Somehow "quick charge" works with it off.
  • Post in thread: 36V system?

    No one asked but, please dont think about 4, 12v batteries with 4 charge controllers. That isnt the way this goes :)
  • Post in thread: EG4 6000XP Monitoring app, lacking pFromGrid Data?

    I am slowly bringing my entire house on solar. Right now 1 xp is routinely powering 2 bedrooms and 2 window ac plus breadmaker. Air fryer, ebike charging. Fridge and now my water heater that I converted from 4500 watts to 1500 I do not run a well pump. With all the loads mentioned. It...
  • Post in thread: stock BMS wire undersized?

    So knob and tube was indeed a good idea in free air!
  • Post in thread: Jk bms balancing issues

    At 3.42 they should be VERY close in voltage. This doesnt mean they are balanced tho. When I balanced my 280k's I charged them to 3.47 and held them there until .005 difference. Then charged them to 3.55 and held them there until .005 difference. Then I called it done... of course you need to...
  • Post in thread: Efficent microwave?

    An inverter style microwave can heat food more gently. but for longer I have an inverter microwave and it draws 2000 watts on high/default. I love dialing back to 30% for soups. (no eruptions) Its wonderful for defrosting. You can soften butter and ice cream nicely without any melting! That...
  • Post in thread: What are good connection point techniques for solid connections

    nice :poop:
  • Post in thread: Thread and member deleted ?

    No one said anything?? That is quite telling...
  • Post in thread: Lifepo4 voltage drop recently

    Cell over voltage in your BMS is set to 3.75. This is a bad practice. I would change that to 3.66 Cell under voltage i would set at 2.8
  • Post in thread: Parallel EG4 6000XPs>>> Poor mans Grid assist??

    Right, They would be in parallel I bet the slave inverter would shut down without grid. I hope Im not going to discover ANOTHER bug that outputs 500v lol
  • Post in thread: wzrelb pure sine wave 5000w 24v power inverte

    Nope, not ok. You are going to need to charge the low one at the very least. They both should be the same voltage.
  • Post in thread: wzrelb pure sine wave 5000w 24v power inverte

    So I guess we found out the problem in your setup. You only had your charge controller charging one of the 2 batteries. You had the inverter feeding on both batteries.
  • Post in thread: House burned down

    What should I do with my 8 50Ah not DIY batteries that already have a BMS. Since they are only 50 Ah getting 8 Class T's set up would starve my children for a month.
  • Post in thread: EG4 6000xp manual is pretty lacking.... I could use some help.

    Thanks for that. Unfortunately I have been thru those steps and the cited thread. My problem is the web view graphs are 1 hour off. It probably needs to be changed somehow in the web page.
  • Post in thread: EG4 6000xp stinks?

    I have been wondering this entire time how you are supposed to open the window without going in the room...
  • Post in thread: Is this a plausible amount of input from the panels?

    So there is something to be said here. Lets say I was pulling in 1000 watts, the shunt on my battery and my BMS would never say 1000 watts because of losses. You will lose just a bit in the wire to your battery, but the biggest loss is the DC/DC conversion. Your PV is at 90V but your battery...
  • Post in thread: Hawaii Condo Living

    The pheonix inverters are awesome for low idle draw.
  • Post in thread: What is the best way to run desktop computer from solar?

    I would think it is do able. It would be a huge undertaking. You would need to cannibalize a pc power supply connector. You would need a 400+ watt 12v supply You would need a 5v supply You would need a 3.3v supply I am not saying these voltages are right. just a general idea.
  • Post in thread: Weird issue with 6000XP 🤷‍♂️

    Good news! Yeah it will be slow. There isnt a whole lot of energy between 3.5 and 3.65. That means you are nearly done.
  • Post in thread: 2 parallel 6000XPs pseudo schematic - Is my wiring right?

    Hate to state the obvious but dont forget to get the house mains off of there then before you connect the 6000xps. Perhaps Im reading that wrong, but still worth saying.
  • Post in thread: What do you experts think of this solar+battery+inverter system for my small RV?

    Are you really looking to draw 400 amps or is that a type-o?? I dont know much about multiplus's, is this one only 3000 watts?
  • Post in thread: 18kvp & 6000xp Date and Time settings

    Bad things? What could happen besides ac charging window be 1 hour off?
  • Post in thread: Got the EG4 XP up and running! Need some help lol

    Got the lights on, on the dongle? How many? Any flashing?
  • Post in thread: Is this a plausible amount of input from the panels?

    Yes! BUT, summer is typically a lot worse at sustained peaks. For instance, here in March, I can hit 100% just about any good day. In the summer I never see 100% rated. That could be because I have my panels angled at 42 degrees for fall and winter being the priority. Alas I am too lazy...
  • Post in thread: BMS active balancer becomes unbalancer as cells age

    There is no memory with lithium batteries. Cobalt and lifepo4 included.
  • Post in thread: Your preference, DIY or rack?

    This thread is probably the answer to your question. https://diysolarforum.com/threads/continuing-diy-or-give-up-diy-to-buy-already-assembled-battery.81270/
  • Post in thread: I’m not an electrician SO ….

    Pretty simple to understand that.... I think 99% of us took it that way.
  • Post in thread: Luyuan battery case

    No reasonable idea here lol
  • Post in thread: Got the EG4 XP up and running! Need some help lol

    oops, thats 250 / 70
  • Post in thread: Lifepo4 cell compression, for a stationary AND low capacity set up, useful or useless ?

    Some are compressed well, some are compressed with an afterthought. My non DIY batteries are compressed with a thin metal shell with "locking tabs" and tape from the factory. Good enough?? Who the F knows.
  • Post in thread: GUIDE to properly Top-Balance and Charge a LFP Battery: Part 1

    I dont believe there is any need for this. The idea is to charge to a voltage that the BMS starts balancing that is in the hockey stick curve of the charging process. If you dont have that info or its not available, dont worry too much. Even balancing at 3.5 yields very limited gains. If you...
  • Post in thread: Correct size Wires for Batteries

    Not sure that makes sense. The context is wrong. That statement came from someone who wanted to be able to max draw their batteries. You and I are not looking for that. We have a different situation. I dont fuse the total output of the batteries... I fuse the wire that I selected to use for...
  • Post in thread: lol

    7. Its ok to buy extra inverters as an upgrade. Backups are great!! I am in the process of setting up a secondary system with my old but still useful 8X 100Ah AGM batteries. I have an extra inverter, charge controller and batteries! Now I will have 2 systems. I can use the 6000xp I have to...
  • Post in thread: Aptos 370w panels. WOW

    Yes, but mine are at 32 degrees and 15 inches off the grass. So negligible bifacial gains I think.
