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.
We have CE/IEC /ROHS/EMC/MSDS/UL...etc.
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.
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
Yes, we welcome sample order to test and check quality.
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.
Our batteries can compatible with the leading brands in the market, such as Victron, SMA, Goodwe, Imeon, Solis, SAJ, Growatt, Luxpower, Voltronic, Deye etc.
Our Powerbox Pro, PowerDepot H5B, B51100 need to purchase WiFi module, which can realize APP monitoring function of IOS and Android system.
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.
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.
We recommended to use 0.5C rate.
Stop charging
Stop charging and find out the cause of the trouble.
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
Because the charging voltage is too low, you can try to adjust charging voltage at 53.5V or 54V.
Battery data status is abnormal. battery gets into over-discharged protection, you can read the battery information on the monitor.
It could be a power connection short-circuit, you can turn off the battery, check the cause of the short circuit.
Battery capacity become smaller, you can storage battery replacement or add more modules.
May the total voltage lower than 35V, you can check the total voltage.
