Communication between the LiFePO4 battery and the inverter can be beneficial, but even if they do not communicate, they can be used together. You can set battery-related parameters (such as charging voltage, charging current, discharge cut-off voltage, etc.) on the inverter to control the charging and discharging of the battery.
Q: Can battery packs of the same specification purchased at different times be used?
A: and the date of use of the battery, the smaller the difference in charge and discharge characteristics will be. Parallel connection of new and old batteries will inevitably lead to differences in charge and algeria number data discharge characteristics. If there is no significant difference in their usage levels (for example, the difference in time of purchase of the battery is less than three months, and the old battery is not used frequently), they can be used in parallel. If there is a difference in performance after parallel connection, it will not affect the actual use.
Our customer has an example: The customer bought two 48V 200Ah battery energy storage systems and connected them in parallel for several months. At first, their SOC differed by as much as 10%. We recommend that customers continue to use them and fully charge and discharge the batteries every few months to allow the chips to learn more fully. If one battery is discharged and the other has SOC remaining, there is no need to stop discharging. This is because the batteries with SOC remaining will be discharged, and the empty batteries will be charged.
