① After the inverter/charger is powered on for the first time, the battery capacity displayed on the
LCD may be inaccurate. To display the available battery capacity accurately, the below process
of self-calibration and self-learning is necessary.
 When the battery voltage reaches the low voltage disconnect voltage or reaches the float
charging voltage, the inverter/charger calibrates the battery capacity for the first time.
 When the battery goes from the over-discharged state to the fully-charged state, the
inverter/charger calibrates the battery capacity again.
CAUTION
When the connected lithium battery (with BMS) is equipped with a battery capacity
display, the lithium battery capacity will be displayed as per the BMS.
