I guess we can use standard inverter from different brands on the battery by removing the DC DC by dropping the voltage as normal 😢

Best regards for you wonderful video! I have 2 questions: why use dcdc to elevate voltate to 400V?this not lose efficiency of all system? Second, Have you think is possibile to upgrade 16s 100Ah batteries to 16s 300Ah keeping same electronics?Pack will charged as well?

[@lassdaily8334]

Thank you for this amazing video. I got to know a lot from it. Very informative 👏🏾. So huawei is going smart by this hidden technology. I couldn't find the exact amp and voltage of the battery before watching your video. Count me in your followers now from Africa (Mali)

I'm surprised about the fact taht inside this battery is a ordinary 50 Volt LFP unit. So it might be easy to connect a batterapack with far more capacity in parallel or not? Does the control unit calculate the capacity or does it only protect overcharging or underdischarging?

it is li phosphate from datasheet

Unfortunately, my rule is electrical faulty, is there a way to continue to use the memory anyway?

[@cinelerraeasy]

Would it be possible to connect external Lifepo4s from other brands to the BMS module? is there any communication between bms and cells?

[@sasssassike294]

I see a fan on the BMS board that often makes a buzzing sound on my batteries. Would it be possible to replace it with silent? Can you provide the specifications of this fan? By removing the battery terminals on the BMS, is there also a risk that the BMS will block permanently?

Vynikajúci výklad, perfektná robota, ojedinelé video tohto druhu. Konečne som pochopil funkciu bateriek Huawei - vynikajúci systém!

The big problem of this battery system is the self power consumption. Value of 60-70W are normal, so about 1.7kwh/day of loss are normal! That's a lot more than other battery brands.

Thank you. I was looking for ,thank you again

Спасибо друг!

Wonder if we can find its rs485 protocol so we can connect not-Huawei battery to the chain.

Thank you very much for the great teardown. I have already installed about 30 of these batteries, and it's great to see them from the inside and to see that they are well put together. Huawei says there is a dehumidifier inside the battery. Did you encounter such a part inside the battery? Would it be possible for you to do a teardown from the DC/DC on top of the batterytower?

[@valjuvic]

Thank you for the inside look !

[@sasssassike294]

Also, did you put the battery back together and it worked without any issues?

[@CosminRotaru]

If the battery module also has the DC-DC, what is the controller box doing? I mean the separate box that is needed besides the battery itself...

[@valjuvic]

Do you know if there if there is a spec on the 4 blue external connector ? I'm trying to source a cable Thanks in advance
