In the off-grid state, the LG Chem battery can only supply power to loads of maximum 5KW
(such as RESU10H_Type_R). For the first operation of the inverter with LG Chem battery,
either PV or grid needs to power the inverter to activate the LG Chem battery.
The SOC limits of Li-ion batteries can be modified via the iSolarCloud App by qualified
personnel.
If the battery has not been used or fully charged for a long time, it is recommended
to charge the battery manually every 15 days to at least 15% to ensure battery life
and performance.
3.3.1 Charge Management

The emergency charge management function is to protect the battery from the damage
caused by long time excessive discharge. The inverter cannot respond to discharge com-
mand during emergency charge. The following tables describe the emergency charge condi-
tions for different types of batteries.
