  • SOC Change Description

    1. How does the SOC change from 99% to 100% when the battery is about to be fully charged?
    When the SOC is greater than 99%, the battery switches to float charging and the charging current decreases gradually. Finally, the SOC reaches 100%.
    2. When the battery temperature is low, the charging power is displayed as about 300 W, but the SOC does not change. Why?
    When the internal temperature of the battery module is low, the internal heating component starts to heat the battery. The heating power is 300 W (typical value). When the heating component is working, the battery is not charged and the SOC does not change. Battery heating helps to keep the cell at a proper operating temperature and prolong the service life of the product.
  • Checking Cable Connection when the Battery Fails to Be Upgraded

    If the battery fails to be upgraded, check the cable connections by referring to Electrical Connection. If the upgrade fails, reconnect the cables correctly and perform the upgrade again.
  • Delayed Upgrade Description

    After logging in to the inverter, if the FusionSolar app detects that the LUNA2000 firmware version is outdated, the app prompts you to upgrade the LUNA2000. You can choose immediate activation or delayed activation. If you choose immediate activation, the LUNA will be upgraded immediately after the firmware package is uploaded. The upgrade process takes approximately 30 minutes. If you choose delayed activation, the activation of the firmware will be performed four hours after you log out of the app.
  • How Do I Recycle Used Batteries?


    The Company does not recycle batteries. Contact local recycling agencies to handle batteries.

    Step 4 Recycling companies handle recycling. The recycled lithium batteries are at the disposal of the recycling companies.
