6.3 On-Grid Supply
By using the On-Grid Supply function, when the power of grid supply is not
sufficient for the load, the SuperCombi will invert to provide enough power to
all the loads together with grid.
Take Fig 19 as an example, the Max Grid Current Limit is set to be 9A, if the
total AC load is 11A, if the On-Grid Supply function is enabled, the SuperCombi
will work as an inverter to provide another 2A to the load.

6.5 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
voltage of the DC port of the SuperCombi is higher than the actual voltage of
the battery poles during charging, which results in a longer charging time;
Otherwise, the voltage of the DC-side port of the SuperCombi is lower than the
actual battery poles voltage during inverting, causing the battery to stop
discharging before it reaches the discharge cutoff voltage. General Speaking,
the charging time is prolonged since the effect, and the capacity of the battery
cannot be fully utilized during discharge either.
If the “Line Loss Compensation” function is selected, the actual battery voltage
can be sensed by the SuperCombi by installing the remote voltage detection
