If the demand for AC power still increases, the external AC circuit breaker may still trip if nothing is done. This
problem can be solved by the Generator function. If the total demand for energy exceeds the maximum external
power supply, energy can be added to the AC outputs load by means of the inverter
Example
See Fig. 16, Input AC current is still limited to 20 Amps. This is not enough to supply the total load (30A)
connected to the AC output load, and the current form battery (Inverter) will supply the remaining 30 20 = 10A.
This means that the restricted amount of external AC power will be supported by energy from batteries.

CAUTION
For safety unit the transfer relay is immediately switched off when incoming AC power fails in
operation so that there will never be a high voltage on the shore cable inlet when it is not connected.
