  • Post in thread: Always out of balance for my BYD 8S 220AH Pack? What to do?

    The problem is The Ant BMS does not balance unless charging current is below 1Amp or any cell is over the set threshold When I discharge the BYD pack below 24V, some cells are 2.8V but some are 3.0V. It's pretty big different and looks like I could not bottom cell easily without a dedicated...
  • Post in thread: TechDirect BYD BMS in pre-built units: Can anyone read this Chinese label?

    According to that chinese manual, the standard is referred to 25C degree, value may change depended on temperature. Personally, I dont think max/std/min make sense to me

    "The do (cell balance when its) on charge (but the max balance current is) 200 ma"
  • Post in thread: Anyone has experiences with wifibox for MPP Solar?

    I just hook the wifi box up with my LV2424 today. No 12V input needed for the wifi box (YAY, and the manual says it requires AC adapter but in fact you dont need it) Default it sends data to power-datacenter.com and honestly, it does not look secure or safe (no https) so... Is it possible...
  • Post in thread: BYD 24V LiFePo4 Battery Modules

    I got from battery hookup, the first batch that saying 4.5kWh I am doing less than 0.2C for charging & discharging, and I did heat up the battery pack, so YMMV It’s always possible that the BMS isn’t reporting the correct capacity, I would need to buy a battery capacity but hard to get one in...
  • Post in thread: MPP AIO: Battery got drained when in Solar Only Mode

    This evening all my ups are triggered due to the mpp solar has been shut itself off strangely. Checking the BMS of my BYD Pack and found low voltage cut off is activated, wonder why Recently we are expeiencing rains and snows, so the battery is not getting charged via solar. and I did set...

  • Post in thread: Does anyone try to claim warranty of MPP Solar product?

    I got the LV2424 from usa-mpp-solar 2 months ago and I am extremely happy with my purchase. I am following the guide and get everything working But from yesterday... the USB Port of the inverter is not working. I tried with 3 different computers and same for all of them. Trying to contact...
  • Post in thread: Backfeeding the grid

    You can choose off-grid mode or Hybrid Mode (Backfeeding) The problem is the backfeeding only happens when battery is fully charged. In my case, I have 1.6kW solar but 9.6kWh Golf Battery system, it will never get fully charged unless i choose so. According to the manual, backfeeding is a real...
  • Post in thread: BYD 24V LiFePo4 Battery Modules

    testing full capacity of my BYD pack again with hall effect sensor only able to measure 3.925 kWh out of the pack and I know the hall effect sensor isnt as accurate as the one Will has (10% higher than my other clamp meter) so it's about 3.53kWh available to use Looks like the Ant BMS...

  • Post in thread: Active Equalizer (Balancer) and BMS.

    I am in the same boat, but I now think about it, why not just get another pack? and this ebay one does not look like a active balancer, so far only qnbbm/deligreen one are proven working correctly with max 6Amp batrium watchmon elite would be the best one for that but it is not out yet, and it...

  • Post in thread: Chargery BMS now with Low Temp Cutoff

    How many temp sensor does this BMS have? Considering buying this instead of the Ant BMS for my other BYD packs but I really need multiple sensors to have accurate data for low temp cut-off (Ant BMS is great but want to explore alternative options)
  • Post in thread: Tiny BMS vs Ant BMS vs Chargery BMS vs Other Cheap BMS

    Firmware upgrade is great but we have to see long term it's same as car, it does have software update too but rarely happen
  • Post in thread: $72 ANT BMS: Current Report by BMS is only half of the actual current

    The problem is when it’s going over the value, it cuts charge/discharge and no power until voltage diff is within the range of your value. for small pack maybe it’s fine, at least it didn’t work out for me on my BYD pack. I set to 0.5V just want to make sure it didn’t randomly cut off power
  • Post in thread: MPP AIO: Battery got drained when in Solar Only Mode

    So what does solar input do? charge into the battery? But you have a 5048 unit and have phase settings, you may need to split into PV1 and PV2? no idea
  • Post in thread: Chargery BMS now with Low Temp Cutoff

    Is the 1A balance real for the chargery BMS? Is it passive or active?

  • Post in thread: 230VAC all-in-one + Step down converter -VS- 110VAC all-in-one?

    I think using 230V Asian/EU model is not a great idea in NA. 1. It's adding a point of failure in the system when using step down transformer. The reason we want to use All-In-One is for simplicity. 2. The step down you posted is only rated for 2500W continuous usage. You may need two, and...
  • Post in thread: Does anyone try to claim warranty of MPP Solar product?

    Thanks for your tutorials and reviews. I am more confident with my purchase now.
  • Post in thread: TechDirect BYD BMS in pre-built units: Can anyone read this Chinese label?

    according to the label 3.6V+ I assume it does top balance.

    Thank you! How long it takes to get to Canada? (I'm in Northern Ontario, hopefully faster than NE :P )
  • Post in thread: TechDirect BYD BMS in pre-built units: Can anyone read this Chinese label?

    200mA is not enough to balance it. If you really really really need to monitor, consider buy a new BMS
  • Post in thread: Newbie question: can the 24v pip all in one safely connect to a Tesla module?

    I think it's possible but be aware in the custom settings, the battery cut off voltage is 20V as lowest, when grid available is 22V charging to 90% is about 24V. Tesla battery can go down to about 18.5V, recommend is 20% @ 19V so by using MPP, essentially you can only using <60% of the...
  • Post in thread: TechDirect BYD BMS in pre-built units: Can anyone read this Chinese label?

    Is there any reason you want this particular BMS? otherwise, Daly BMS would fit as well
