6.3 Load Priority
If the power supply of gird is insufficient, the Load Priority function will make
sure the load has the priority to get the power and only the remainder of the
power will be charged to the battery.
Note: If the total load is higher than the limit of AC IN, the gird breaker
may trip, unless you choose On-Grid Supply function.
Fig 18. Load Priority Function Example
Take Fig 18 as an example, the Max Grid Current Limit is set to be 9A, if the
total AC load is 7A, the current to be charged to the battery will be 2A, no
matter how much charge current is set.
Similarly, if the charge current is set to 200A and DC load is 120A, then the
charge current to the battery will be 80A.
6.4 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 13A, if the On-Grid Supply function is enabled, the
SuperCombi will work as an inverter to provide another 4A to the load.
