The unit is in ON BATTERY mode; the load is between 75% and the overload limit.
NOTE: In the case of a sustained overload, the Home UPS will be turned off automatically after one minute, and will wait in the fault state for a minute. After that, it will restart again. If the overload still persists, the Home UPS will be turned off again after one minute, and will wait in fault state for one minute and restart again. In the same way, it will try for three restarts. If the overload still persists, it will stay in fault state permanently until the unit is restarted with push button. If the time interval between two consecutive overloads is more than 5 minutes, then the latest overload is considered as a fresh overload and three restart cycle will begin again.
