Fig 19. On-Grid Supply Function Example
6.5 Separate Supply
With the separate power supply function being selected, when the
SuperCombi is used in areas where grid connection is not allowed, the mains
can only supply power to the
‘Power’
end, if the total load current is greater
than the set ‘Maximum Mains Current’. In this case, the ‘Short Break’ end will
only gain power from inverter to ensure that the mains circuit breaker will not
open.
Fig 20. Separate Supply Function Example
Take Fig 20. as an example, the Max Grid Current Limit is set to be 9A. If the
total AC load is 13A, since the
Separate Supply
function, the relay will turn off
and the Grid will provide 6A to
‘Power’
end and the SuperCombi will work as
an inverter to provide another 7A to the
‘Short Break’
end.
6.6 Wire Compensation
The large current from battery will produce a significant voltage drop during the
cable transmission process.Thus, there is a voltage difference between the DC
port of the SuperCombi and the actual voltage of the battery. As a result, the
