for 2 hours after the state of charge (SOC) reaches 100%; and the load ratio
uctuation is less than 10%.
● The UPS has generated no battery overtemperature, overvoltage, or overcurrent
alarm. No generator is connected to the UPS.
● The mains, batteries, charger, and discharger are normal. No overload alarm is
generated.
● The SmartLi has generated no alarms related to lithium batteries.
