11.2 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 oat 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.
11.3 Checking Cable Connection when the Battery Fails
to Be Upgraded
If the battery fails to be upgraded, check the cable connections by referring to 6
Electrical Connection. If the upgrade fails, reconnect the cables correctly and
perform the upgrade again.
11.4 Delayed Upgrade Description
After logging in to the inverter, if the FusionSolar app detects that the LUNA2000
rmware version is outdated, the app prompts you to upgrade the LUNA2000.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 rmware package is
uploaded. The upgrade process takes approximately 30 minutes. If you choose
delayed activation, the activation of the rmware will be performed four hours
after you log out of the app.
