Inverter Mode (Online UPS)
This mode is usually in use, when grid is very unstable or if a very high quality AC-source is required for sensitive
equipment. To operate the system in this mode it requires to charge the batteries all the time in order to have
enough power available.
In this mode, the load is connected to inverter. In case of inverter failure (low battery, overload, etc.), the AC-
Output switches to grid/mains power. Switch over time is less than 6ms.
If inverter is operating again the load is switched back to inverter power.
