Dyness

Good day. 4.8kwh battery is 15-strings battery,and the nominal voltage is 48V，5.12kwh battery is 16-strings battery，the nominal voltage is 51.2V. Obviously，These 2 type of batteries have different platform，But the inverter only can output one volatge platform.It will cause one battery overcharge.

Hi Please add my account Whatsapp +86 17625812876 Thanks

Hi I have checked your connection Settings and found that they are all normal. Could you please show me the information of Li-BMS? Thanks

Hi This is Tour from after-sales department of Dyness. 1.What is the SN of the battery? 2.Are there any alarms after the battery is turned on? 3.How long does it take for the battery to turn itself off after it is turned on? You can add my Whatsapp：+86 176 2581 2876 Best regards Tour Shen

Hello,Sir/Madam This is Tour from after-sales department of Dyness. Can you add my account of Whatsapp :+86 17625812876 If you have another contact information,Please provide to me. Best regards

According to my judgment, if your current battery has no other problems, you just need to increase the capacity of the battery to get more power output and the problem can be solved.

Now the reason for your battery alarm is that the load power is too large and exceeds the energy that the battery can output.

The maximum output power of a battery is about 1200W, how much power is your load? Because the battery makes a bibi sound, it indicates that the battery is over-discharged or over-current. According to the voltage and SOC of your battery, it is normal. So I judge that the fault of your battery is an over-current alarm. You should consider adding one more battery or multiple battery packs. , to ensure that the output of the battery can fully guarantee the normal operation of the load.

46V minimum.

Hi You can contact me first，I will communicate your request to our technical director.. whatsapp：+8617625812876 e-mail：[email protected] Thank you

No, this is prohibited, the same model can only be used in parallel with the same model.

Please contact me: Whatsapp：+8617625812876 e-mail：[email protected] 1. What is your battery model? How many batteries are used in parallel? 2. Does it communicate with the inverter? What are the parameters for charging and discharging settings? What is the cutoff value？ 3. What is the voltage and SOC of the battery when the fault occurs?

Hi there.The cut-off value of the battery is recommended to be set to 20%, and the minimum can be set to 15%.Thank you.

Hi ，You can give me your battery SN.If you've never done a firmware upgrade, I'll let you know if you need an upgrade based on the information you provided.

You can see the picture.This is the pin definition of a dry contact.
