    EG4 3000W Inverter - Warning code 19 - Lithium Battery communication failure

    I had similar problem, thanks to this forum for helping me fix it. I am posting just to reiterate the solution and my experience. I have the 3K all-in-one and a single LifePower4 battery. To eliminate the error 19 I needed to switch cables (use the "Pin 1-2" cable!!), setting 5 should be Li4...

    EVE 280AH cell has low voltage after storage.

    To follow up on this thread, the suspect cell, and the battery as a whole, is doing fine so far. I charged, top balanced, charged, and then did a capacity test discharge over about 3.5 days. According to the Overkill BMS the battery provided the full 280AH, although barely (so the entire 100%...

    Can't change setting 21 LV Cut Off in Growatt SPF 3000TL LVM-24P

    Good thought, you were right. I increased setting 12 "voltage point back to utility when SBU or Solar first is selected in setting 01". This was misleading because I selected Utility FIrst in setting 01, but evidently setting 21 is still tied to setting 12 in this case even so. I'm good to...

    Can't change setting 21 LV Cut Off in Growatt SPF 3000TL LVM-24P

    I can't enter my own voltage in setting 21 Low DC cut-off voltage. As soon as I hit the enter button it reverts to 23.0V. I have tried battery type at 05 with both USE and US2 but no joy. What gives? FYI I have a DIY EVE 280AH 24V 8S with overkill BMS and not using communication (not sure if...

    EVE 280AH cell has low voltage after storage.

    They have tapped holes, photo below. Regarding the 2.125V, your response is what I expected. However I already started with Zwy’s suggestion. I have the cells in 8s 24v battery with overkill bms charging with a cheap bench power supply cc limited to 5A. See screenshot below. Cell number 1 is...

    EVE 280AH cell has low voltage after storage.

    I measured directly on cell terminals. Thanks

    EVE 280AH cell has low voltage after storage.

    Ok that’s encouraging that at least there’s a chance the low voltage cell may be ok. I’ll proceed with your advice. It will be interesting to see if the suspect cell can hang with the others under load after top balancing. Thanks

    EVE 280AH cell has low voltage after storage.

    I started building an 8s 24v diy the other day from 8 Eve 280ah cells. I bought these brand new from china 1.5 years ago but unfortunately they have been sitting in storage since I got them and ignored. Voltages are below: EVE 280AH 2/27/2023 3.291 3.291 3.290 3.290 3.287 3.283 3.264 2.125...

    Chinese New Year – or what I call “Where the ^$%^ is my battery shipment? (order now)

    Understood. Although shipping time is important, I was mostly concerned about quality, so at least I got cells that were manufactured and packed up before CNY impacted those steps.

    Chinese New Year – or what I call “Where the ^$%^ is my battery shipment? (order now)

    Thank you for this information. I was oblivious to this issue and your post prompted me to action. I had purchased 8 of the 280ah last summer from Dongguan Billion Electronic Technology and had just decided to get another set (to add) and went to this forum to see the latest advice last Friday...

    Problem paying on Alibaba, help please

    Thanks for the tip! Over the past week or so I had tried 2 different cards, both always failed, and I appealed too many times to count. This morning I bought a cheap 10,000mAH power bank (about $10 + shipping) from a supplier on Alibaba using one of those cards, and it processed successfully...
