5. Load Support Mode
And now the other load adds and switches on and the current increases to 11A. This is
•
where Load Support is needed.
The bidirectional converter starts operating as inverter to add 6A to the 5A that is avail-
•
able from the shore-side: Total 6+5=11A, and no overload on the AC supply.
As soon as the load reduces to less than 5A, any current that is left over will be used to
•
recharge the battery.

MODE 2: INVERTER as Priority Support
1. INVERTER Mode:
When the battery voltage is not lower than (B2-10) voltage value, inverter mode takes
•
priority to supply voltage to AC OUT for load consumption.
