Issue Category

  • Battery

    • What is so special about these LiFePO4 battery cells?

      LiFePO4 battery cells are among the safest Lithium-ion batteries on the market. The cell chemistry makes a thermal runaway overheating almost impossible. The cells are inherently safe even under extreme conditions and therefore they don't pose a fire risk.LiFePO4 battery are characterised by a high cycle stability which translates into a long lifetime even under intensive load conditions.

    • Which certificates do you have?

      We have CE/IEC/ROHS/EMC/MSDS/UL...etc.

    • The battery is so heavy, will it damaged easily on the road?

      This is also a matter of great concern to us. After long-term improvement and verification, our packaging is now very safe and reliable. When you open the package, you will definitely feel our sincerity.

    • How to solve the technical problem?

      24 hours after-service consultancy just for you and to make your problem to solve easily. You can also write to info@dyness-tech.com

    • Can I have a sample order?

      Yes, we welcome sample order to test and check quality.

  • Configuration

    • Why can't the battery communicate with the inverter in the matching list?

      You can refer to the user manual to change the dial settings, or check whether the communication cable is in poor contact, if still not work, please contact our after-sales team.

    • What are the brands of inverters that your batteries can compatible with?

      Our batteries can compatible with the leading brands in the market, such as Victron, SMA, Goodwe, Imeon, Solis, SAJ, Growatt, Luxpower, Voltronic, Deye etc.

    • Is it possible for Dyness battery to support APP monitoring?

      Our Powerbox Pro, PowerDepot H5B, B51100 need to purchase WiFi module, which can realize APP monitoring function of IOS and Android system.

    • Why the batteries bank losing all the energy to zero SOC?

      It is recommended to perform the following operations:
      ① Set the constant charging voltage of the battery to 53.5V to ensure that the battery can be fully charged to calibrate the SOC,
      ② Set the battery's float charge voltage on the inveterate to 53V to ensure that when the battery enters a fully charged state, if a small power consumption
      current discharge occurs, the battery can start to float charge when the battery voltage drops to 51V, and then calibrate when fully charged SOC.
      In this way, the SOC of the system will remain accurate all the time.

    • How many parallel connections can the battery support?

      The B4850, B3, B51100, and A48100 can support up to 40 units in parallel, while the Powerbox and PowerDepot can support up to 4 units in parallel.

    • What is the charge/discharge rate of Dyness?

      We recommended to use 0.5C rate.

  • Installation

    • What to do if the Charge state is at a high temperature and the alarm indicator is RED?

      Stop charging

    • What to do when the buzzer sounds off?

      Stop charging and find out the cause of the trouble.

  • Connection

    • What to do in case of communication failure?

      You can check these follow possible cause one by one:
      ① The DIP setting of the master is wrong
      ② The battery type of the inverter is wrong
      ③ Communication cable used incorrectly
      ④ The communication cable is incorrectly connected at the battery communication port or the inverter communication port
      ⑤ The battery firmware version is too low to support the inverter

    • Why can't the battery be fully charged to 100%?

      Because the charging voltage is too low, you can try to adjust charging voltage at 53.5V or 54V.

    • Why does the battery have no DC output?

      Battery data status is abnormal. battery gets into over-discharged protection, you can read the battery information on the monitor.

    • Why the power cable sparks once power on and ALM light RED?

      It could be a power connection short-circuit, you can turn off the battery, check the cause of the short circuit.

    • Why the DC power supply time is too short?

      Battery capacity become smaller, you can storage battery replacement or add more modules.

    • What is the reason for the indicator not responding after turning on the power?

      May the total voltage lower than 35V, you can check the total voltage.

  • Other

    • The user manual is lost.

      Please go to the download center of Dyness official website to download the relevant type of online user manual.

    • Are you a factory?

      Yes. We are specialized in the R&D, production and sales of renewable energy storage solutions and Li-ion power battery systems. It currently runs two production factories in China, located in the cities of Yangzhou and Taizhou, both in the eastern province of Jiangsu.

    • How do you ship the goods and how long does it take to arrive?

      7 days for sample; 40-45 days for bulk order. Airline and sea shipping is also optional.

    • Are you able to handle shipment transportation?

      Sure, we can arrange the shipment to most places as required.

    • What is your warranty?

      We offer 10 year warranty or 5 years warranty. we ensure at least 6000 cycle life for the LiFePO4 battery pack.
