    EVE LF280K 16S JK B2A24S15P-CAN

    Strange, I have not seen that problem on mine ?

    EVE LF280K 16S JK B2A24S15P-CAN

    You can (and should) calibrate the overall voltage and current on the jk bms. What I find is that once you do that the cell reading becomes incredibly accurate. The wire resistance under zero load has no influence on the cell voltage readings. PS: don't overthink it ?

    Newbie from Portugal building a house :)

    Just to finish "stage 1" of my project. The 14 pannels are installed totalling 6.44Kw of panels The Deye 5KW is in and working. The 17x 280Ah EVE LifePO4 with JK BMS are there too. We are living in the house now and averaging a usage of 15KWh per day (heat pump only draws about 1KW to warm up...

    EVE LF280K 16S JK B2A24S15P-CAN

    But if they are qualified by grade A and B based on their capacity and Docan doesn't sell grade A, how do I have 3 cells above 280Ah? I am not sure about that theory... I think there is a big variation between these models of cells and its luck of the draw. I don't believe they are all tested...

    EVE LF280K 16S JK B2A24S15P-CAN

    Not sure I agree with the grade A/B qualification so not sure how to answer? Grade A I guess, bought brand new from Docan. They are the ones with single m6 post on each terminal not like the ones on the picture of this post

    EVE LF280K 16S JK B2A24S15P-CAN

    That is pretty common on the eve LF280k unfortunately. Here are my test results (discharge only to 2.6v but that doesn't make much difference)

    DEYE 5KW hybrid inverter going past set absorption voltage ? HELP

    I am going to set temp compensation to 0 and see if the delta goes away. Thanks, greatly appreciated ?

    DEYE 5KW hybrid inverter going past set absorption voltage ? HELP

    Yes, 17s. No sensor, and temperature is about 18 degC but the battery temperature sensor isnt connected. Temperature compensation is a good call. It is set as per default mV/C/Cell is set to -5 Not sure how to interpret that since the inverter has no information about the number of cells? The...

    DEYE 5KW hybrid inverter going past set absorption voltage ? HELP

    Hi all, I have connected my 17s 280Ah lifepo4 battery to my deye 5kw inverter this week. Today its the first time I am being able to fully charge it due to cloudy days. The inverter is going past the battery set voltages and I cant figure out why. On the Battery settings page I have it set to...

    Newbie from Portugal building a house :)

    yes, but because the house is not completely finish and the electric installations hasn't been signed off we cant register the solar installation.... Portugal... there is always something u need to do to get something else done I have the "solar sell" unticked now

    Newbie from Portugal building a house :)

    Here in Portugal the netmeetering period is only 15 minutes, and even then most people report that it doesn't work, othets report that they count your injection as consumption ? I have set my sistem to zero export because I haven't had inspection yet and if you are not registered as having...

    JK BMS Question

    I am having the same problem as the guy in the video. The bms doesn't accept the name change. I thought u also had that problem from your description on your first post? If so, how did you overcome it? Thanks

    LF280k damaged during shipping, safe to use?

    thanks for the advice, unfortunately Doncan is saying "you need to return the cell". These were ordered from China, so it is more expensive to send this one back than to just order a new one. I understand that they send me good cells its not their fault one arrived damaged, but it is not my...

    LF280k damaged during shipping, safe to use?

    Hi all. Received a new batch of cells, one of them suffered an impact during shipping. Vootage and internal resistance measure fine. Do you think its safe to use?

    应该是电池反冲了 BATTERY RECOIL, BATTERY BACKLASH

    A fuse lets current flow in both directions and doesn't limit maximum voltage, I am not sure how that will be helpful?

    应该是电池反冲了 BATTERY RECOIL, BATTERY BACKLASH

    Thank you, would it be an idea to use a Diode in series to the positive line ?

    应该是电池反冲了 BATTERY RECOIL, BATTERY BACKLASH

    Does this mean one shouldn't just unplug the psu from the mains once charging is finished? I was thinking of using a mains timer but reading this it might not be the best idea?

    Best inverter for setup in Europe

    Why do you say that deye aren't easily available? In you case I would get 2 x 5kw deye A few websites in spain Have them, seen them in france also, I am sure you can find them up there too https://suministrosdelsol.com/en/hybrid-inverter/1522-deye-5kw-2mppt-hybrid-inverter.html...

    24v lifepo4 battery charger recommendation

    Will it not trip out for being at constant max current if charging a lifepo4 from low SOC?
